For their rock is not as our rock; even our enemies themselres being judges.-Hent. xxxii: ill. 

PREFACE. 

The present paper is a revised and enln,rged e~ition of 

Professionn,l Paper 14, 1 published by the United States 

Geologicn,l Survey in 1903. In the 13 years that have 

elapsed since that paper was published there has been 

very noteworthy progress in the ch01nical analysis of 

igneous rocks. This progress is evidc:5nt in the greatly 

increased nmuber of analyses here tabulated, more 

than twice as many hav:ing been published between 

1.901 andl913, inclusive, a period of 13 years, as. were 

published between 1884 and 190'0, inclusive, a period 

of 17 years. It. is also evident in the improved 

quality of the analytical work, and one n1ay venture 

to think that the publication of Professional Papers 

14 and 28 2 encouraged and to son1e extent brought 

about this improv01nent. 

The better1nent in quality is 1nanifested both in the 

gren,ter proportion of more accuTate analyses and the 

n1ore frequent deter1nination of ~he minor constituents; but even now our knowledge of the occurrence 

of the rarer elements in.igneous rocks is· sadly deficient 

for many countries in which .the rock analysts, though 

doing active and accurate work, have failed to determine 1nost of the 1ninor constituents. 

The p~:csent collection 01nbraces the years from 1884 

to 1913, both inclusive. With very few exceptions all 

the analyses ·published in Profession.al Pap·er 14 are r~­

produced here, for that paper is now out of print and 

1nay be inn,ccessible to many. . 

Further search of the .literature has yielded a considerable nmnber of additional ~nalyses that w'ere 

published within the tin1e limits of the first collection 

but which were omitted f1·om it. Several sets of analyses publis~ecl prior to 1884 have also been.incluclecl 

because they seemed to be of special importance or 

because they \vere not incorporated in Roth's Tabel..., 

len, covered by Professimial Paper 28. Among these 

may be mentioned fiawes's analyses of· the rocks of 

Now England and New Jersey, and analyses of rocks 

of the West Indies and of Stunatra, published, respectively, by Cleve and Verbeek. Although the end of 

1913 was :fixed on as the final elate to which the work 

should be brought, yet a nu1nber of analyses published 

t WMhlngton, n. S., Chemical analyses or igneous rocks published from 1884 to 

1900, with a critical discussion of the character and use of analyses: U. S. Geol. 

Survey Prof. Paper 14, 1903.

1869 to 1884, arranged according to the quantitative system of classification: U.S.

subsequently have been included. These ~mbrace 

many which were contributed prior to publication by 

generous friends and which have appeared since, 

as well as a few which, for one or another reason, it 

·seemed to he advisable to include. Professional Paper 

14 01nbraced 2,881 analyses, and this pn.pe~ en1braces· 

8,602, including, as has been said, practically all those 

in Professional Paper 14 but not those from Roth's 

Tabellen,. published in Professional Paper 28. 

The collection is confined to analyses of igneous 

1~ocks, though it .includes some analyses of· ortho~ 

gneisses. Dr. Paul Niggli, of the University of Leip~ 

zig, is engaged, I understand, in the compilation of the 

analyses of ri1eta1norphic rocks, a work which will be 

of great· benefit to the student of these, for the most 

extensive collection of the analyses of these rocks so 

far available has been the selection published by 

Grubenmann.3 The analyses of meteor~tes ];lave been· 

recently collected by Farrington/ who has classified 

the stony meteorites according to the quantitative 

system. He has also recently published 5 a complete 

collection · of descriptions and analyses of North 

An1erican meteorites to January 1, 1909. In this connection may be mentioned the collection of analyses 

of meteorites and of "some terrestrinl peridotites published by Wadsworth. 6 

An aim k.ept constantly in mind has been to 1nake 

the present cqllection as complete and accurate as 

possible and, in a sense, definitive. The search 

through the 1iterature has therefore been very exton-

. sive, systematic, and thorough, the serial publications 

examined having extended frmn 1883 to the final 

date. Its extent may be gathered fron1 the "List of 

publications examined," which is ·to be. found on 

pages 38-44. In this search the extremely complete 

Library of the United Stat·es Geological Survey served 

as a basis and was examined very thoroughly. In this 

connection I take pleasure in expressing n1y thanks 

to Miss Julia L. V. McCord, librarian, and to tP,e other 

officials of the library for their many courtesies and

I have also availed 1nyself of Prof. A. Osann's 

valuable collections 9f analyses/ from which I have 

taken a number that had escaped my notice. ThE1 

many analyses and the bibl~ography given by Iddings 

in volum~ 2 of his Igneous Rocks (1913) have also 

been collated. A collection of analyses of Swiss rocks 

from.· 1900 to 1915 2 reached n1e too late for collation 

with my collection.. The san1e is true .of. a set of 

analyses of Queensland rocks.3 The authors of both 

were so kind as to send me many of the analyses prior 

to publication. · 

Through the kindness of F. W. Clarke, chief che1nis-t, 

the records of the chemical laboratory of the United 

States Geological Survey were placed at my disposal, · 

and the numerous analyses there recorded up to 

January 31, 1914, are included here. I would express 

' my sincere appreciation of the courtesy of Mr. Clar~e 

and the many geologists of the Survey, for whom the 

analyses were made, in thus making available,- much 

of it prior to publication, a great amount of most 

valuable material. 

It is also a pleasure to acknowledge my great indebtedness to many friends and fellow petrologists . 

who have been so kind as to contribute analyses 

prior to publication and whose great generosity is 

deeply appreciated. Among these may be specially 

mentioned Prof. A. Lacroix; Dr. K. Inouye, director 

of the Geological Survey of Japan; Prof. U. Grubenmann, and the Geological Survey of Switzerland; Mr. 

J. J. H. Teall, ex-director, and Mr. A. Strahan, director 

of the Geological Survey of Great Britain; Mr. R. D. 

Brock, director, ana other geologists of the Geological 

Survey of Canada; Drs. G. W. Card, W. N. Benson, 

. J. W. E. David, II.· C. Richards, and· W. H. Twelve:-

G. P. Merrill, L. Milch, E.· W. Morley, P. Niggli, P. 

Quensel, G. W. Tyrrell, and T. L. Watson. The 

lllany valuable analyses contributed by these and 

others have added n1uch to the completeness of the 

present collection. . A nun1ber of hitherto unpublished 

analyses made by me are also included. 

Considerable changes, both additions and omissions 

have been made in the text. The additions consist 

in the incorporation of new matte.r and the expansion 

of the old. The omissions include considerable matter 

relative to the quantitative system, which is now so

the entire discussions of the distribution of magmas 

and the av~rage rock have had to be omitted, as it 

was found to be quite impossible, with the time at my 

disposal, to work up the vast n1ass of data so as to 

~rriv·e at a satisfactory and adequately complete 

treatment. Both of these topics are to form the subjects of sep~rate publications. 

In the tables the separate columns for C02 and BaO 

are omitted and one for the magmatic symbols in the 

quantitative classification is inserted. These symbols 

will be found very useful (mo.re so than the systematic 

names), after a little· experience with them, in giving 

a concise idea of the chemical character of a rock and 

its relations to 0thers. These. symbols are also used 

for the page headings, instead of the magmatic names 

used in Professional Paper 14. 

All the norms of the analyses given in Professional 

. Paper 14 have be.en recalculated. -Indeed I have 

recalculated personally all published· norms, to in~ure 

their uniformity and to verify or correct them. In 

this .connection I would express my thanks to Dr. 

l-1.. H. Robinson, who son1e years· ago very kindly 

calculated for me rriany norms, which, however, were 

not used be~ause· I subsequently decided to calculate 

every norm n1yself. . It can not be hoped that all 

analyses have been collected or all errors. avoided in 

the present compilation. The list of errata on page 

67 of Professional Paper No. 28 is sufficient evidence 

that such a hope is vain.4 :My attention w~s called to 

several such errors, both of omission and conunission, 

by friendly critics, and I trust that the same interest 

will be shown. in regard to the present collection. I · 

would also deeply appreciate the contribution of 

·papers embodying further analytical data, especially 

inaugural dissertations and other difficultly accessible 

literature, for incorporation in supplernents which it is 

hoped to issue in the future. 

·To my friends Whitman Cross and Joseph P. 

Iddings I am deeply ind.ebted for much helpful criticism and·· advice, especially in the selection of the 

1nag1nati~ names. I must also express n1y thanks to 

Prof. M. Kawa1nura, of Kiushiu University, Japan, for 

;his great assistance in reading ·.rnuch of the proof. 

I would express my sense of deep obligation to Dr. 

Arthur L. Day, director of the Geophysical Laboratory 

of the Carnegie Institution of Washingto11, for his gi·eat 

liberality and kindness in allowing me to devote a very 

large part of my time during the last four years at 

·this laboratory to the prosecution of the present work 

and in permitting· its publication by the Geological

CHEMICAL ANALYSES OF IGNEOUS ROCKS. 

By H. s. wASHINGTON·. 

THE IMPORTANCE OF ROCK ANALYSES. 

In the ·first two or three decades of the nineteenth 

centm-y, when the study of rocks as such was being 

differentiated frmn that of minerals and of rock terrn.nes-that is, when the science of petrography was in 

its infancy, little attention was paid to the~r chemical 

features. It is true that a nUm.ber had been analyzed, 

but most of these were of such a character as to lead 

the investigator of those early days to consider theni 

n1inerals, as was the case with the first described 

lherzolite and wehrlite·. In contradistinction to well-. 

defined minerals, rocks were regarded as merely aggregates of minerals, occurring in presumably fortuitous 

cmnbinations, and lacking that definiteness or constancy 

of cmnposition in one n1ass or in different n1asses which 

would justify their chemical study. as a whole. As, . 

however, they became more and more the subjects of 

special research, beginning with the earliest investigations of Cordier, 1 a ~now ledge of their chemical compo-: 

sition assmned gradually increasing interest. The 

great in1portance of this side of the study of rocks was. 

first clearly recognized by ~bich, 2 who pointed out, as 

early as 1841, the necessity of a knowledge of their 

chemical cmnposition for the solution of such problems as their oTigin, n1ode of formatio~, and connection 

with the interior of the earth, as well as the value of a 

cotnpariso.n of their analyses as a proper basis for their 

classification and nmnenclature. To him, therefore, 

is due the credit of introduCing the chemical composition of rocks as a basis for their classification; though 

the good influence of this s~ggestion for their right 

understanding was largely nullifi~d by the coincident 

use of the feldspars alone as one of the main fn.ctors of 

classificn,tion,3 • an idea which has had a deplorably 

retarding influence on the development of syste1natic 

petrog1;n.phy for nutny years, and which even now 

holds 1nany systematists fir1nly in -its grasp. 

For about· 30 years after Abich's publication chemical analyses occupied a prmninent pm:1ition in- petrographical discussions, being mnployed largely for the 

purpose of detennini.ng the probable n1inera~ cmnpositiion of rocks. Abich, in the work just cited, had 

adopted as a 1neans to this end the ratio of the oxygen

of the bases to that of the silica, and was .thus enabled 

to calculate approximately their mineral cmnposition, 

as Ra_mmelsberg and o·thers did later. 

. A modification of this method, known as the "Oxygen-ratio" (Sauerstoffquotient), was introduced by 

Bischof, 4 and was long employed for the correlation of 

rock analyses and for the investigation of the question 

whether or not the various oxides were present in 1:ocks 

in stoichiometric proportions. This ratio for any given 

rock is obtained by dividing the amount of the oxygen 

in an· the bases by that in the silica, and was supposed 

to be characteristic of different broad groups. This 

supposition was eventually found to be unwarranted, 

as rocks of very diverse chemical or mineralogical 

characters were shown to have the san1e or sin1ilar 

oxygen-ratios. It ·is notewm~thy that, although Roth 

himself pointed out this and other. grave objections to 

the use of this ratio/ he giyes it in connection with the 

separate analyses in all his tables-even in the last one, 

published in 1884. He justifies ·this by saying 6 that. 

·it is done "only in the absence of a better n1eans of 

comparison, as well as to make it possible to compare 

the older and newer analyses." 

· It was also shown by Roth and others that rocks 

could not be referred to simple chemical forn1ulre; in 

other words, that the oxides were not present in stoichiometric proportions. This, Indeed, is one of the 

most im.portant results arrived at by Roth from his 

study of ~he analyses collected by him and first pub-, 

lished in 1861. 

Soon after Bischof's suggestion of an oxygen ratio 

there appeared 7 Bunsen's well-known hypothesis of the 

formation of igneous rocks by the Inixtiure of two supposed original magmas-=-the "norn1al trachytic" and 

the "nor1nal pyroxenic." 8 For the application or the 

discussion of this hypothesis, analyses were, of course, 

all impottant. Founded, as the hypothesis was, on 

insufficient data, it had to yield to the evidence furnished by the n1any analyses to which it gave rise. 

With the abandonn1ent of this view of the genesis 

of igneous rocks, and because of the coincident intro4 Bischof, G., I.ehrb. chemischen and physicalischen Geologie, vol. 2, p. 631, 1849.

to contrast "bamltic" with "trachytic," or else ""feldspathic'' with "pyroxenic."

10 CHEMICAL ANALYSES OF IGNEOUS ROCKS. 

· duction of the microscope in the early seventies, 

analyses lost much of their importance. Though they 

were still published, it is evident that they were, as a . rule, inserted perfunctorily in petrographical writings, 

in obedience to custom, as ornamental embellishments. 

Little or no stress was laid on them, and the efforts of 

the petrograph_er were devoted chiefly to the elucidation of the purely mineralogical and textural characters 

· of the rocks described. 

The microscope poured a flood of light· upon the 

mineralogical composition as well as on the texture of 

rocks and rendered easy and certain of ·attaininent 

results which by the older methods, based on analysis, 

had been attained only with difficulty or not at all. 

At the sam~ time the collapse of Bunsen's hypothesis 

left for the time being no general theory of rock formation and genesis in jts place, Durocher's liquation 

hypothesis 1 and Roth's firs~ suggestion of differentiation 2 attra~ting little attention. Petrographers 

were too busy collecting and assimilating the vast 

mass of facts discovered through the microscope to 

be able to devote much of their energies to theoretical 

studies. 

With the opening of the last decade ·of the nineteenth century, however, there arose an interest in 

theoretical petrology in contradistinction to descriptive petrography, which had prevailed since 1870. 

This was started by the work of Lagorio, Teall, 

Rosenbusch, Brogger, Iddings, and others, and 

since that time analyses have occupied a more and 

more prominent place in petrological discussions. 

They are no longer ornamental adjuncts, but essential 

parts of most petrographical publications, on which 

much of the discussion hangs, and from which the 

most in1portant ·conclusions are drawn. The crystallographic and optical properties of the constituent 

minerals and the details of texture are no longer the 

main subjects of investigation, . but are finding their 

place with the chen1istry of rocks and the broad and 

far-reaching physico-chemical studies based on this. 

The microscope is sharing the throne with the balance. 

It is coming to be recognized _by petrologists in· 

general that the study of igneous rocks is in large part 

the study of silicate solutions and their equilibria, 

often co1nplicated by the presence of volatile conl-

. ponents, and is thus to b~ regarded as essentially a 

special branch of physical chemistry. It is true that 

some of the conditions under which th~y ar.e· forn1ed 

in nature are not yet reproducible with the pres- · 

ent laboratory facilities and. that the ·solutions 

involved are of great con1plexity, but these difficulties 

may be and are gradually being overcome, so that it 

would seem that the study of rocks is now being 

phteed on its proper and sure basis. For this rock 

analyses are all-important-indeed, indispensable.

THE CHARACTER OF ROCK ANALYSES. 

GENERAL CONSIDERATIONS. 

With the growing interest in rock analyses it is of 

the utmost importance that they be used intelligently, 

not only in their application to theoretical discussions, 

but, which is of especial interest here, with· a just 

appreciation of their character and applicability to 

the purpose in view. It is a son1ewhat surpi·ising 

and, it must- be-said, a rather saddening fact that the 

critical judgment of petrographers in general as regards rock analyses often seems to be in abeyance or 

wholly lacking. Though there- has been in recent 

years a marked in;tprovement in this respect, yet 

there is still among them now, as there seems 

always to have been, a. tendenoy to place in1plicit 

confidence in· th~ results of analytical work-to accept 

readily whatever figures the analyst may furnish, 

with seldom an attempt at a critical estin1ate of 

the worth of· the analysis or a comparison of it 

with the chemical ·character of the rock itself as revealed by microscopic study. It seems to be taken 

for granted by most petrographers that the analyst, 

like the proverbial king, can do i1o wrong.. This asf:?Umption applies, of course, not to the personal good 

faith of the analyst, but to the analytical processes, 

which, possibly because they belong to one of .the 

exact scien.ces, are for the most part tacitly assumed 

by the petrographer-to be infallible. It is noteworthy 

that this attitude of mind obtains, not only among 

beginners, but among the foremost workers in the 

science. There are, it is true, 1nany examples of the 

application of. expressed· criteria· in the selection of 

analyses in well-known papers, especially in recent 

years, but in all these examples the criteria applied are 

few and qu1te inadequate to the purpose, being confined, for· the most part, to the freshness of the rock. 

Comparatively few petrog;raphers seem· to recognize 

the difficulties and _uncertainties of analytical work 

or to. display. any practical acquaintance with its 

methods. 

It goes without saying that this way of regarding 

analyses is ·totally at variance with the .best interests 

of the science. Analyses constitute .the basis· of much 

of · th~ investigations and discussi<?ns with which 

petrographers and ·petrologists must occupy theinselves, and it is surely not the part of wisdoin to erect 

elaborate structures on foundations of whose stability 

and careful workmanship one is not assured. Tillie 

. and labor will be saved in the mid, and the superstruc- · 

ture, however well built in itself, will have a far better 

chance of · wi thstan'ding the ravages · of time and the 

attacks of critics if all the rotten and unsound blocks 

in its foundation are removed and only the best nnd 

strongest material is retained. 

A consequence of this unquestioning confidence in 

the results of analytical work. is that it. is frequently

intrusted to a student in chemistry, one with little or 

no exper~ence in the analysis of rocks and with no 

appreciation of the cotuplexities and difficulties inherent in this department of quantitative analysis .. 

That the results furnished by such inexperienced and 

to this extent incmnpetent analysts should-be received 

with the greatest . caution is a truis1n to anyone 

acquainted by actual experience with "the difficulties 

and· con1plexities of rock analysis. But Hillebrand 1 

and Pirsson 2 have expressed so clearly and concisely 

the views which I hold that I can do no· better than 

refer to the1n. . It is certainly remarkable and significant that in petrography the most difficult and intricate work is intrusted to novices, and that their re- . 

suits are accepted by nearly all with the same confidence that is given to the work of an experienced 

·analyst. 

This generalla..."'City muong petrographers as regards 

the quality of rock analyses i~ only too painfully evident in the present collection. There is an astonishingly large proportion of poor work, much of it' of such 

a character that it would seem that even a tyro would 

reject the analys~s as hopelessly inadequate for use. 

Analyses are given with sununations over 105 or b.elow 

96. Some analyses of leucite-basanite show 8lkalies 

so low that 10 or more per cent of quartz must be 

present, even though in the calculation all the potash 

is assigned to orthoclase and all the soda to albite. · 

S01ne analyses of rocks Tich in oliVine show 30 per 

cent of alumina and only small amounts of ferrous 

oxide and magnesia. In certain analyses of alkalic 

rocks the alkalies have . not been separately determined.. Rocks with abundant regirite c'ontain no ferric oxide, and son1e with sodalite contain no chlorine, 

to judge fr0111 the figures furnished. 

Lagor~o's long, elaborate, and classical discussion 

of rock Jnagn1as and the relations of phenocrysts and 

groundinass is based on numerous analyses, of which 

scarcely any have been judged by me to be of" superior" 

quality, so that very few of them appear in Part I of 

these tables. Vogt's well-known discussion of eutectics centers largely around five analyses of graphic 

granites in which only five constituents are determined and which n1ust be relegated to the inferior 

analyses of these· tables. 

The chief reason for this low standard of criticis1n 

on the part of· petrographers as regards analysts and. 

analyses would seem to be that, while all of them are 

necessarily conversant with chemistry fr01n the theoretical side, few have knowledge of the theory of quantitative analysis or experience in its methods. The 

· fact is not generally recognized that the complete and . 

adequate analysis of an ·igneous rock is one of· the 

most complex and in some respects one of the difficult problems o~ analytical sci~nce, demanding not

only chemical knowledge and manipulative skill, but 

often the exercise of considerable judgn1ent derived 

fro~ experience in solving the perplexing problems 

which may present themselves. 3 . 

In view of the present greatly increased importance 

of chemical analyses in petrography, it can justly be 

insisted that the ability to 1nake an accurate and 

con1plete chemical analysis of an igneous rock should 

fonn an essential part of the training and equipment 

of every petrographer, for by .such knowledge one 

can best judge the true value of an an3lysis, see where 

'errors haye possibly crept in, . and discrin1inate between what is good an.d worthy of use and what is bad 

and to be rejected. 

In view of this state. of affairs it will.be pertinent 

to discuss at some length the essentials of a good 

analysis, th~ theoretical and practical criteria. by 

which analyses may be judged, and, in a rough way, 

to .estimate the weight which may be given to any 

analysis in theoretical discussions. 

REPRESENTATIVENESS. 

CHARACTER OF THE ROCK 1\fASS. 

An analysis of an igneous rock is of value in direct 

ratio as it fulfills three conditions-that the specimen 

analyzed is representative of the rock mass, and that· 

the analysis itself is accurate and con1plete in its 

determination of the constituents present. We may 

consider these three factors in the order stated. 

The representative character of the specimen depends partly on the character of the rock mass and 

partly on the amount of material taken. If the 1nass 

is uniform or if a single uniform fa~ies is the object of. 

investigation· two courses of procedure are possible. 

A single representative 0 specimen from one ·locality 

may be selected for analysis, or pieces of several specimens collected f.rom different parts of the mass may 

be taken, pulverized, and mixed, and the analysis 

made of this nrixture. The course 'last described 

labors under the disadvantages that the an~ysis can 

not be checked by analyses made by others, and that 

uncertaillty will always exist whether the mixture of 

several specimens really represents the composition 

of the whole better than does a single specimen. 

· Generally it is by far the best plan to select a definite locality, preferably one that can be identified later 

and that is not likely to become inaccessible through 

building or other operations, the rock fr01n which can 

· be considered representative of ·the whole 1na8s, and 

make the analysis of a specilnen frmn this. 

If -there should be doubt as to the general uniformity of the whole ·mass, it is better to take samples 

from different parts, even if this procedure should 

involve considerably more analytical work, for a 1nuch 

more detailed knowledge . will thus b~ .g~ined, and 

a cr. llillebrand, w. 1<~., op. cit., p. 16. 
12 ·cHEMIC~L ANALYSES OF IGNEOUS ROCKS .. 

important features which may otherwise be· overlooked may be rendered evident. 

In making analyses of a heterogeneous mass sue h as 

a stock or dike with marginal facies, it is lik~wise always the wisest plari to have separate analyses made 

of the different facies, even if the determination of the 

c~aracter of the mass as a whole is the only object,in 

VIeW. 

The decision as to the representative character of 

the specimen selected must. be left to the collector 

and it would seem natural that a petrographer wh~ ~ad the a~aly~is of a rock in view and who thought 

I~s analysis might be of value would carefully consider this question in the field and select his material 

accGrdingly. The . evidence is conclusive, however 

that 1nany ·specimens analyz.ed have been collected 

W:it~ ~o reference to· this point, a fact that has greatly 

diminished the value of the analytical work afterward expended on them. · · 

In connection with this subject the question naturally arises whether rock masses are indeed so uniform 

in character that any single specime11 will truly repre..: 

sent the whole, and whether specimens from different 

parts of an apparently uniform mass, even if taken close 

together, may not differ widely in composition. :/1, 

.~u~l treat~ent of this fundamentally important topic 

IS Impossible here, bu~ the outcome of such a discussion would be that, though differences may· be found 

in modally or normatively (but not texturally) eutaxi..: 

tic or schlieric masses, yet a rock mass which is meO'ascopically and microscopically uniform will generally 

furnish specimens that, if examined by two or n1ore 

competent analysts and by reliable methods, will 

yield results that are practically identical. In other 

words, in the terms ~f the new classification, they 

would fall in the same subrang, or very close to the 

same border lines. 

No investigation appears to have been made especially to decide this point, but the present collection 

furnishes a number of examples that sustain the conclusion just stated. Among them may be mentioned 

the analyses of the Butte quartz monzonite, (No. 5, 

I. 4. 3. 3 and Nos. 6, 7, 8, II. 4. 3. 3), the phonolite of 

the Black Hills (Nos. 10 and 11, I. 6. 1. 4), the essexite 

of Salem Neck (Nos. 4 and 5, II. 6. 2. 4), the keratophyre of Marblehead Neck (Nos. 20 and 21, I. 4. 1. 

3), the leucite banakite of the Yellowstone Park 

(Nos. 10 and 11, II. 5. 3. 3), arrd the Quincy grnnite 

(Nos. 28 and 29, I. 4. 1. 3). . -

The ·specimens should, of course, be taken from 

fresh, unaltered rock, for only such specimens represent 

the chemical character of the magma. In some places, 

however, absolutely fresh material is not to be had; 

but if there is more than a very slight degree of alteration an elaborate analysis is not necessary. We can 

hope to obtain from an analysis of such a rock but a 

general idea of its magmatic character, and, though the .. 

~ai~ constituents should be determined with accuracy, 

It Will scarcely be worth while to determine the 1ninor 

constituents e:x:cept for special purposes, as for the 

study of ro?k weathering. If the alteration is slight 

the proportiOns ?f the main oxides will not be much 

· changed, but those of the minor oxides will be relatively 

much more so. 

·b 

AMOUNT OF MATEiiiAL. 

The amount of material that will adequately represent the rock mass is a matter that deserves the careful 

.consideration of. the petrographer and the analyst. 

For actual analysis at least 10 grams of pulverized rock 

should be av.aila?le, but, in view of the possibility of 

the redeterminatiOn of some or all of the constituents· 

or the determination of some for which large portions 

are needed, it is well to have 20 or 30 gra1ns.1 N 0 

definite rule can be laid down as to the an1ount that 

should be taken, which- depends on the granularity of 

the rock and whether it be porphyritic or llOt. For an 

analysis o! fine or medium-grained, aphanitic or glassy 

rocks, W~ICh are not porphyritic or are only finely so, 

a few: chips, al?lounting to 30 or 40 gr~ms, will be quite 

suffiCient. Of coarse-grained rocks, or those that are 

coarsely porphyritic, much 1nore ·will be needed the 

amount bei.iJ.g dependent on the coarseness of the·~rain. . ~or ne_arly all ordinarily coarse-grained rocks, or those 

In whiCh the phenocrysts are less than an inch in 

diameter, an ordinary small hand specimen, or even 

a smaller fragn1ent, will be quite sufficient the size 

being detern;tined by the judgment of the petr~grapher. I~ the rock 1s. a?normally coarse, as are some pegmahtes and nephehte syenites, much niore must be taken 

perhaps several pounds. At a few places a larO'e rock 

surface must be measured to determine the r~lative amounts of the various minerals, and prop~rtionate 

am.ounts of th~s~ n1ust be taken and mi..~ed for analysis. 

This last conditwn, fortunately, is of rare occurrence, 

and an analysis n1ade of such material n1ust be regarded as only approximate at best. 

If more than 50 grams or so of n1aterial is used it 

is not necessary to pulverize the whole, for a sample 

may be obtained by making successive crushings and 

quartering, as in assay work. Care must be taken to 

do this. prop~rly ~nd systematically, according to 

. methods de~cnbedin any work on assaying. 

lt should be noted that the whole of the small 

amount of chips or_ sample obtained by quartering 

must be pulvenzed. and used for analysis. The rockmaking minerals differ so greatly in brittleness that 

if only a portion of the sample be pulverized it will 

·not represent the true average composition for the 

more brittle minerals, such as quartz and the feldspars, will be reduced to powder first, while the 

toughe.r ones, as hornblende, pyroxene, and mica, will -------- ·1 Cf. Hillebrand, W. F., U.S. Geol. Survey Bull. 148, p. 23, 189i. 
ACCURACY. 13 

need mo~·e crushing and grinding. ·If, therefore, the 

las·t portions, which do not pass easily through the 

silk sieve, are rejected, the analysi~ will' show a 

slightly n1ore salic cmnposition than ~xists in fact. 

On the other hand, owing to the same fact, the fine 

dust lost d1u·ing the operations of crushing, sifting, 

and grinding will be composed chiefly of salic minerals, so that, strictly speaking, all rock analyses show 

a s01newhat niore fernie compositi01~ than they should,· 

though the error 1nust be very slight.1 

1\HCROSCOPIOAL EXAl\HN ATION. 

A microscopical exan1ination of the rock in thin 

section should always precede the chemical analysis. 

~11is examination will not only reveal clearly the 

general composition and freshness of the rock, but 

may indicate its minor constituents, such as zirconia, 

sulphur trioxide, and chlorine. 

~1le petrographer can thus indicate to the analyst 

the minor constituents to be estimated and those for 

which it is .not worth while to ~ook. Some of the 

main analytical processes may also be modified and 

shortened by a knowledge of the gener~l character of 

the rock. Useless labor may thus be saved to the 

careful and thorough hut nonp~trographical .analyst, 

who, in the absence of such indications and in the 

conscientious endeavor to have his analysis complete, 

may spend n1uch tin1e looking for constituents that 

are absent, or present in only insignificant amounts. 

ACCU~ACY. 

DETEH.l\fiNING ]<'ACTORS. 

Assuming that the sample annJyzed is representative of the rock n1ass, the degree of correspondence 

between the figures yielded by the analysis and the . 

true coinposition of the rock is dependent on two 

factors-the accuracy of the analysis and the degree 

of its completeness. 

By accuracy is n1eant the degr~ee of pr~cision with 

which the constituents sought for have been determined, quite apart from the fact whether all those 

present have or have not been determined or separnted one' frmn another .. The n.ccuracy of an anaJysis, 

which n1ay be discussed apart from its completeness, 

depends on the personal ability of the analyst to make 

n,nalysis, on the relin.bility and adequacy of the methods employed, and on the· quality -of the reagents arid 

appar.atus used. . 

The factor. of the analyst has ah·efl.dy been touched 

on in speaking of the practic(;) . of intrusting 'rock 

analyses to students, and the obvious truth that 

' Tho only lnstcmco known to mo where this has been especially Investigated is 

that In S. Ztlloski's study of the amount of quartz in granites (Tschermak's MineraL 

11fltthcll., vol. 14, p. 350, 1895). He shows by.determinations of silica that the 

dust l>roduccd In the pulverization of granites is notably richer in feldspar relatively to quartz and dark minerals than the coarser portion of the powder. 

th~ personal factor is a most important one rn the 

making of analyses .need only be ~tated here. Thus 

the work of a trained and experienced chemist will 

presumably be of far higher character than· that of 

a beginner publishing his first analysis in .an inaugural dissertation or that of a student in chemistry 

to whom the analysis of a rock has been giv(;)n for 

practice. It is true that the man of experience may 

not be a good analyst, or that he may be hampered 

by. bad methods or poor. reagents, and, converse~y, 

the work of the beginner may be, and often is, of 

very good quality; but the fact remains that the 

work of the tyro .will not carry the weight· of that of 

the expert in the absence of confirmation of its character by ·other evidence. 

The employment of reliable and accurate methods 

is of course essential to g.ood analytica1 work. As 

·this paper, however; is not intended to be a treatise 

on the analysis of rocks, the matter can be only 

briefly touched on for the especial purpose of pointing out to the nonana]ytical petrographer some of 

the more common pitfalls that beset the path of him 

who undertakes the analysis of rocks. 

In view of the wide experience of the. chemists of the 

United States Geological Survey, and the uniformly 

high standard of excellence shown by their work, it 

may be recommended that the methods adopted by 

them 2 should be employed whenever possible, at least 

until improvements on them, OI,' better methods, shall 

· have been devised. Too high co:qm1endation can 

hardly be bestowed on their analyses, especially the 

later ones, which stand in a class apart from almost 

all others, as a study of the mat~rial here collected 

will render evident. 

POSSIBLE ERRORS. 

The fact must not be lost sight of by petrographers 

unacquainted with quap,titative ana]ysis that in certain portions of the processes there ~s liability to 

serious error, due either to inherent defects in the 

method or to the necessity for special care in manipulation, such care as can be exercised o,nly by a careful 

and experienced analyst. The most prominent of 

these sources of error will be briefly stated. · 

· Liabqity to error attends the determination not 

only o(the .minor constituent~, which is generally of 

comparatively small moment, but unfortunately that 

of most of the main and important chemical constituents, where it becomes a matter of great importance. 

The determinations which will be discussed are those 

of silica, alumina, ferric and ferrous oxides, magnesia, 

lime, soda, potash, titanium dioxide., phosphorus pentoxide, and manganous oxide.

H. S., The chemical analysis of rocks, New York, 1910. 
14 CHEMICAL ANALYSES OF IGNEOUS ROCKS. 

In regard to silica, Hillebrand, 1 has clearly shown 

that· the methods usually employed do-not yield ac.,. 

curate results, but that two· or more· evaporations, 

alternating with filtrations, together with prolonged 

ignition over the blast, a~e advisable. He also shows 

that silica is not wholly thrown down by ammonia 

·or sodjum acetate along with the aluminum_ and iron, 

and that it is appreciably soluble in meited potassium 

pyrosulphate. But assuming that the silica has been 

corrected for impurities· by evaporation with hydrofluoric acid, as must always be done; it may be said 

that thes·e errors incident to its determination are in 

general of small magnitude and do not seriously affect 

the v-alue of the· analysis, especially. as this constituent is almost invariably present in greatest amount. 

Alumina is, of all·the constituents, the one most 

liable to serious error, the. general tendency being 

almost uniformly toward too high figures. This 

tendency arises in part fron1 the fact that alumina is 

determined by difference, so that the nondetermination of certain cqnstituents raises its apparent amount. 

Increase in the apparent amount of alumina, due 

to imperfect separation of magnesia, is probably the· 

error of considerable magnitude most commonly met 

with in rock analyses, esp~cially in those of the more 

fernie (basic) rocks. It arises from the fact that magnesium hydroxide tends to fall down with aluminum 

hydroxide on precipitation with ammonia. This can 

be prevented only by the presence of sufficient ammonium salts an,d by repeated precipitations, either 

with ammonia alone or with sodium acetate as well. 

These conditions are easily neglected by the .inexpe~ienced analyst, and in compiling the present collection so many analyses have been noted where this 

errpr has certainly been made, and so many others 

where it is strongly suspected but not definitely 

provable, owing to .the insufficiency of the petrographic description·, -that I must add my word of 

warning to those of Hillebrand 2 and Pirsson. 3 

Another error, probably of very frequent occurrence 

but of less magnitude, and hence less readily detectable, 

is that due to the use of ammonia water which is not 

fresh and which has absorbed carbon dioxide from the 

atmosphere. A certain, though generally a small, -

amount of lime will then be precipitated along with the 

alumina and weighed with it. 

A third error, which may be of very considerable 

magnitude, ar!ses from the use of ammonia water 

that has been kept jn_ uncoated glass bottles. The 

glass is invariably decomposed and the ammonia 

water becomes contaminated with impurities, chiefly 

silica, which add to the apparent weight of the alumina 

of the ·rock. This error can r~adily be avoided by 

1 U. S. Geol. Survey Dull. 422, p. 91, 1910, and Jour. Am. Chern. Soc., vol. 24, 

pp. 362 et seq., 1902. 

2 Hillebrand, W. F., U.S. Geol. Survey Dull.176, p. 55, 1900. 

a Pfrsson, L. V ., Jour. Geology., vol. 4, p. 688, 189fi. 

purchasing the reagent in ceresine bottles and, as the 

ceresine stoppers are not usually effective in excludi.tl.g 

carbon- dioxide, by transferring it to a glass-stoppered 

bottle tha·t has been coated internally with paraffine. 

For the same reason it is also well, in the most accurate work, to make the ammonia precipitations in a 

gold or platinum basin. 

In regard to the determination of ferrous oxide, 

Stokes 4 has shown that ferric sulphate exerts a marked 

oxidizmg effect on pyrite, and, starting from this fact, 

Hillebrand 5 demonstrates the unreliability of the 

Mitscherlich method, con1monly employed in Europe 

for the determination of ferrous oxide-that is, decomposition with sulphuric acid in a sealed tube. It should 

also be noted that the glass of the tube is likely to be 

seriously attacked. This method often gives, especially in rocks rich in iron, too high results for ferrous 

oxide. Decomposition by hydrofluoric_. acid in an · 

atmosphere of carbonic acid is to be preferred, which, 

however, in the hands of inexperienced analysts, is 

liable to give low figures for ferrous and correspondingly high figures for ferric oxide,· in consequence of 

the partial oxidation of the ferrous oxide due to careless manipulation. . These errors undoubtedly explain 

a number of anomalous figures for ferrous oxide found 

in the present collection, for these figures do not accord 

with the mineralogical composition shown by the 

descriptions. · 

The error .involved in the determination of ferrous 

oxide through its oxidation. in grinding 6 should also 

· be considered .. Though possibly of in1portance, especially in rocks high in ferrous oxide, if the grinding is 

prolonged and the powder is very fine, I believe that 

it has been exaggerated and that it is negligible if 

the portion of rock powder taken for the determination of ferrous oxide be that used for the 1nain analysis, without furthe'r grinding than that involved in 

preparing· the san1ple for analysis'--a matter of a few 

n1inutes' grinding after crushing.7 

Another possible error in the determination of the 

iron oxides, one -that may be easily made by the novice, 

is that which is involved in the reduction of the solution of the precipitate by ammonia water for determining the total iron. If the current of hydrogen sulphide 

or sulphur dioxide is not continued for a sufficient 

leng.th of time, the ferric sulphate will not be completely reduced to the ferrous state, so that the apparent amount of ferric oxide will be too lo~ and 

that of alumina correspondingly too high. This will 

not, of course, affect the ferrous qxide, as ~his is always 

determined in a separate portion. If r.inc is used for

the reduction of iron, titaniu1n dioxide will also be red:uced to sesquioxide, which will be titrated with potassiuln permanganate, and will add to the appare11:t 

an1ount of ferric oxide. · · 

The source of error in the determination of lime due . 

to the·presence· of calcium carbonate in the ammonia 

wnter has· been mentioned in connection with alu1nina 

on the preceding p_age. 

The error involved in the liability of the magnesia 

to be precipitated in part with the alun1ina, which has 

already beQn noted, will lead to figures that are· too 

low for this constituent. · 

Another error in the determination of magnesia, 

though in general of less 1nagnitude and importance, 

is that involved· in its precipitation as ammonium 

n1agnesiun1 phosphate. Under the conditions usually 

obtaining in this det~rn1ination the.re is .a tender..cy 

toward errors that apparently increase the amount 

of magnesia, owing to the presence of excess of the. 

precipita:J?.t, am1noniun1 salts and free ammonia. 

Since this error is due to the fact that, under these 

conditions, the mnn1oniun1 magnesiun1· phosphate 

contains more phosphorus pentoxide than is called 

for by the ideal constitution, it will not affect other 

constituents but will be positive in its effect, and will 

thus raise the sun1mation, of the whole analysis.- This 

error will usually l;>e sinall, and even if the analyst is 

not expert will be of less Inagnitude· than that involYed in precipitation of 1nagnesia with alumina. 

In regard to the determination of the alkalies, I 

need only add a word in confirmation of the view expressed by I-Iillebrand as to· the advantages of the 

Lawrence S1nith method, both as to accuracy and as 

to tin1e saved. The slight correction necessary for 

the 1ninute mnount of alkalies in the calcium carbonate used is constant and is easily and safely 

. applied; ~hereas the other Inethods of decomposition, 

involving the prelin1inary separation of alumina, iron 

oxides, litne, and 1nagnesia introduce a large element 

of uncertainty and possible error,· owing to the impurities contained in the reagents or taken up from the 

glass vessels. 

The colorimetric meth_od for th~ 'determination of· 

titanium ~ioxide is by far the most accurate and the 

quickest, and should be uniformly used, for the older 

·methods, based on its precipitation by prolonged boiling, are very uncertain unless the conditions are very 

exactly adjusted, especially w4en much titanium dioxide is present, in which case it is .very liable to be 

contan1inated by alumina and ferric oxide. The assumption. which is sometime$ made, that the residue 

loft on evaporation of tho silica with hydrofluoric acid 

represents all .tho titanium dioxide present, is quite 

unwarranted, for this resid110 contains only part of it, 

and also some aluminn., ferric oxide, ri.nd phosphorus 

pontoxide. ' " 

-Beoause of the likelihood of error involved in the use 

of the acetate method, as well as the far greater expo-

. ditiousness of the colorimetric method, manganese 

should always be estimated in a separate portion by 

the latter. 

COMPLETENESS. 

CONSTITUENTS TO BE DETERMINED. 

The ideal analysis should show the percentage of 

every constituent of the rock, and, for practical purposes at any rate, all those that it contains in amount 

sufficient to make their determination a matter of 

interest or whose presence or absence bears on the 

problem for which the analysis is made. 

The amount which may make a constituent worth 

determining and the number ·of constituents to be 

sought will vary, of course, for different rocks. Thus 

for rocks as simple as most granites, rhyolites, and 

anorthosites it is not necessary to determine so many 

constituents as should be determined in nephelite 

syenites .and rocks belonging to the dosalane and 

salfemane classes. But as an analysis should ·truly 

represent the composition of the rocks, as it may, if 

complete, be of use to others for the discussion of 

problems other than the one immediately in hand, and 

as only good ·work should be countenanced in science, 

every analysis shoUld be as complete as it is practicable 

to make it. 

1\:IAIN CONSTITUENTS. 

In every rock analysis worthy of the name all the 

main constituents must be determined. These include 

silica, alumina, ferric and fertous oxides, magnesia, 

lime, soda, .potash,· and water. 

Unfortunately, in manyarialyses the.iron oxides have 

not been separately determined but are given together 

as either Fe20 3 or.FeO or equivocally bracketed opposite both of these. Unless the iron oxides are present 

in very·.small amount-for example, less than 1 per 

·cent-or unless the presence of a considerable amount 

of pyrite or pyrrhotite makes the determinatior1 of 

ferrous oxide v~ry uncertain, this is unjustifiable, as 

the proper separate determination of these two is essential to the complete chemical discussion of the rock 

magma and tlie calculation of the mineral composition, 

either ·normative or modal. This fault and the. error 

involved in the separation of alumina and magnesia 

are the most common defects in r9ck analyses, and a 

surprisingly large number have been rejected from 

Part I of the tables on their account. 

The alkalies are occasionally estimated together (as 

Na20) or determined by the difference from 100 per 

cent. This procedure is followed especially in analyses 

of the more· fernie rocks, but sometimes .in analyses 

of rocks in which the alkalies amount to several per 

~ent. For this form of slovenliness there. should be no 

excuse, except in analyses of rocks composed largely or 
- 16 CHEMICAL ANALYSES OF IGNEOUS ROCKS. 

entirely of such minerals as olivine, magnetite, and 

iln1enite, in which the alkalies can be present only in 

traces at most. · 

The molecular weights of orthoclase and albite are 

so high 1 that in any chemicomineralogical system of 

classification, or in the calculation of the mode, the 

determination ·of both of these oxid_es is of -great importance. Furthermore, the assumption is made that 

the sum of the analysis will be exactly·100 per centan assumption quite unwarranted in view of the great 

rarity of this occurrence, especially when the chemist 

thinks so little of his work as to be unwilling to deterrnine the alkalies properly. 

In some analyses of highly salic or highly alkaliu 

rocks magnesia f).nd lime are not deten:nii1ed but are 

given as "traces." In most of these analyses their 

nondetermination will not seriously affect the results 

of calculation, but it is to be deplored; it shows that 

the work was not first class. In the statement of an 

analysis the term "trace" should indicate strictly and 

uniformly that the constituent has been looked for 

and found, though in negligible amount (0.1 milligram 

or less), but if it is not looked for because it is suppos~d 

to be present in small amount, some such phrase as 

"present., not determined" (p., n., d., not det., or 

undet.) may be employed. The limits assigned to the 

term '·'trace" vary widely, and the present collection 

includes analyses in which this term is used of constituents that are certainly present to the extent of 

1 or 2 per cent or more. This applies especially to 

titanium dioxide. 

MINOR CONSTITUENTS. 

Assuming that the nine main constituents are 

determined, we may now consider those. usu-ally 

regarded as. "minor." Both Clarke 2 and Hillebrand 3 

lay stress upon the importance of their determination 

for the solution of some broad petrological problems. 

Thus the work of the chemists of the United States 

Geological Survey has demonstrated the comparative 

abundance and general distribution of titanium, 

barium, and strontium, and a greater abundance of 

barium along the Rocky Mountain region than in the 

eastern and the extreme western parts of the United· 

States. The presence of vanadium in many .of the 

more fernie (basic) rocks and of molybdenum· in the 

more quaric (siliceous) rocks/ of zirconium in presodie 

and especially nephelite-bearing rocks, and of nickel 

and chromium in very fernie rocks has been discovered by means of complete an~lyses. The correlative distribution of the minor elements has been 

discussed elsewhere. 5 

I One percent of K20 corresponds to 6 per cent of-orthoclase, and the same amount 

of Na20 to 8 per cent of albite. ·

Indeed, Hillebrand has entered so strong a plea 

for completeness in rock anaiysis that little .mor,') 

need be said to convince petrographers of the correctness,of his· position. Since, however, there is a strong 

tendency to regard as adequate for petrographic 

purposes a.rialyE?es in which only the nine main constituents have been determined, further remarks, 

especially in elucidation of son1e special points, 

may not be an1iss. · 

. It is obvious that if a rock carries notable amounts 

of minerals that contain as esse:c.tial ingredients any 

of the minor· constituents, these should &-lways be 

deter;mined. Thus, Cl and S03 shculd be included 

in the analysis if the rock contains sodalite or noselite; 

Ti02, if it contains titanite, ilmenite, hornblende 

augite, or magn.etite; P20 5, if it contains apatite, 

and Zr03 if it contains considerable zircon or eudialyte. 

If these constituents are ·not determined ~he analysis 

will not show adequ.ately the composition of the rock, 

. or, as Clarke puts it, "the petrographer has been more 

thorough than the chemist." 

It is chiefly for -this reason that a microscopical 

study of the rock section should always precede the 

analysis. The conscientious chemist who is not a 

petrographer, and who therefore does not know what 

minor constituents are especially to be looked for, can 

only make sure of the compieteness of his work by 

the determination of everything possible. The results 

of his work will be of value, yet in many analyses part of 

his labor may be quite unnecessary, involving a waste 

of time which would be obviated_ if the petrographer 

furnished with the material ari indication of the minor 

substances that should especially be looked for. 

Although the determination of all constituents, 

even _those which .are present in mere traces, is to be 

desired, yet in practice a compromise must be made, 

generally, between the degree of con1pleteness and the 

time to be devoted to practical analytical work. The 

determination of most of the n1inor constituents takes· 

c.onsiderable ti1J?.e, and if the number of a~alyses to be 

made is great or the time available is short it may not 

be advisable to determine all tl'!e lesser constitue:p.ts, 

but only those essential to a proper understanding of 

the rock. This is· especially true of the rarer substances, such as Zr02, Cr20 3 , V20 3 , F, NiO, CoO, CuO, 

and SrO, as well as S03 and Cl in rocks without the 

sodalite group of minerals~ ·On the other hand Ti02 , 

P20 5 , MnO, BaO, and S, which are now known to be 

commonly present and .widely distributed, should be 

determined in ev.ery analysis that aims at completeness. It is also generally of interest to determine 

Cr20 3 and NiO in the mo~t fernie rocks, expecially if 

olivine is abundant, as they are likely to be present in 

considerable amount. In view of the length· of time needed to make a 

rock analysis and the very considerable addition 

to it involved 1n the. determination qf the rarer 
COMPLETENESS. ·17 

elements the following general procedure seems to me 

to be advisable in investigating a region, locality, or 

volcano where there is much variety in the igneous 

rocks. At least two analyses should be made of each 

of the main rock types, the specimens to be taken from 

different parts of the mass or frmn different flows, and· 

one analysis of each of the 1ninor types. All these 

annlyses should show, besides the nine main constituents, Ti02, P20 5, and Mn.O, but not the rarer elements, 

which need be determined only in two or three of the 

analyses, each representing one of the 1nain types frmn 

tho most salic to the most fernie, as their ainounts and 

variations are small and the verification of their 

presence or absence in the region or in the various 

1nagmas ~s of most iinportance. We would thus 

obtain, with a minimum expenditm·e of time, the 

data needed for a proper petrologic discussion of the 

region in its n.1ain features and a sufficient knowledge 

of tho presence of the rarer elements to permit its 

comparison with others. 

In discussing this tnatter a point to bear in mind is 

that the detern1ination of certain of the 1ninor constituents affects the figures for other and often very 

important ones. 'rhis arises frmn the 1nethocls of 

annlysis necessarily mnployed, in which several constituents are precipitated together in one operation, 

and subsequently son1e of then1 separately cl~tern1ined, 

the :figures for one being represented by the difference. 

Of these those of by far the 1nost influence are titanium 

dioxide and phosphorus pentoxide. These are not 

only ulmost nlways present, often in very considerable 

amount, but their determination affect~ that of the 

highly important ahm1ina. In the course of the 

analysis ahnnina, ferric oxide, titanium dioxide, and 

phosphorus pentoxicle are precipitated together, the 

three last are cletenuinecl separately, and the alumina 

is estimated by difference from the su1n of the four, 

since so far no satisfactory 1nethod has been devised 

for its independent detern1ination. It is obvious, 

therefore, that, if the oxides of titaniun1 and phosphorus are not determined, the figure for alumina 

will be too high. In analyses of all but the n1ost 

sulic rocks the error may be of great moment, for 

these two oxides may be present in a very considerable 

amount, and the alumina is the only n1easure we 

have for the calculation of the runoun t of anorthitemodnl or normative-frmn the analysis. 

Sin1ilarly, the noi1detennination of Zr02 and Cr20 3 

will raise the figm·es for ulumina, since these are also 

precipitated together. In most auulyses, h~wever; the 

error due to these defects will be negligible, owing to 

the minute quantities of these oxides usually present. 

As the vanadiwn is thrown down with the phosphorus as a vanaclomolybdate its amount should be 

subtracted from the P20 5 and not fron1 the alumina. 

Vanadimn also affects the determination of ferrous 

oxide, and if preswnably present in more than traces 

42423°-17-2 

it may be determined and a proper correction applied 

to the ferrous oxide in the most accurate work. 

Fortunately this course will seldon1 be necessary, as 

its amow1t is almost always exceedingly sn1all .. 

As strontia is precipitated with lin1e as oxalate, its 

nondetern1ination will make the apparent an1ount of 

lime too high. But strontia rarely occurs in more 

than traces, so that this error is negligible for all but 

the most accurate investigations. 

Lithium remains with the sodium after separation 

of the potasiun1 as platinichloricle, but has rarely 

bee~1 fo~n.d in quantity great enough to warrant its 

estil~ation. ' 

In Professional Paper 14 the determination of manganese was discussed and the conclusion was reached, 

in view of its usually very sn1all runount and the 

liability to error in alumina involved in the acetate 

method, that its determination was not usually called 

for as essential to good work. Since then the simple, 

accurate, and expeditious colorin1etric 1nethocl for this 

element has been introduced in rock analysis, so that 

it may be said that it is always adYisable to detei·mine 

it. The long list of analyses made by the chemists 

of the United States Geological Survey, as well as 

those made elsewhere, show that, though almost 

nlways present, its amount is Yery small, in general 

little more than a trace. Indeed, it is of interest to 

note iri this connection that Clarke's estimate of the 

average composition of the igneous rocks· of the 

United St~tes shows that the amount of manganese in 

them is only about one-si.."'Cth of that of titanium, and 

is even less than that of phosphorus. In view of the 

great variety of igneous rocks represented by these 

ru1alyses and of the very high character of the ru1alyti-

. cal work, the high figures sometimes found for this 

oxide in analyses a:re to be regarded with suspicion, 

the probability being that in "them the error already 

spoken of has been n1acle. 

That the noncletermination of ma:ngru1ese will affect 

the figures for other constituents is c01·ta~, but to 

what extent is not very clear. If the all.ll;l1ina, etc., 

has been separated with runmonia water, a portion 

will be thrown down and be weighed as alumina. 

Part of that which passes through in the filtrate will 

be thrown clown with calcium oxalate and weighed 

as li1ne. But as manganese oxalate is slightly soluble 

in water, some of the manganese will be till·own down 

as phosphate with the magnesia and weighed with 

this. Little is known of the various proportions of 

the manganese which will thus be distributed, and the 

matter is one that calls for investigation. Hillebrru1d 1 

gives some figures of George Steiger for cru·bonate 

rocks, which .indicate that most of it generally falls 

with the magnesia, ru1 equal or much less amount 

with the alumina, and only a very sn1all portion with 

the lin1e.

18· . CHEMICAL ANALYSES OF IGNEOUS ROCI(S. 

In regard to the determination of water, I am in 

accord with Dittrich 1 and Hillebrand,Z that the rock 

powder taken for analysis should be air dry, and that 

it is advisable (though not necessary) to discriminate 

between combined and hygroscopic water-that is, 

water driven off above and below 110°. The importance of this distinction appears to be much exaggerated, as the amount of "hygroscopic" water driven· 

off is not . constant for any given sample of rock 

powder, but varies with the temperature and the 

time of heating, thus including some of what would 

be called "ignition" water. Furthermore, it is well 

known that a small but perceptible amount of water 

is adsorbed from the atmosphere by rock powder. 

The remarks of Hillebrand on the inadvisability of the 

method for the determination of water by ''loss on 

ignition'' will be concurred in by every experienced 

analyst who has considered the matter, because of 

the oxidation of ferrous oxide and the loss of volatile 

constituents. . 

Except where minerals containing water or hydroxyl, 

as analcite or muscovite, are primary components of 

a rock, the determination of water is not essential to 

a proper comprehension of the rock magma, hut its 

amount, as well as that of carbon dioxide, is of importance as a measure of the freshness of the rock. The 

determination of water must therefore be regarded as 

essenti~l to every rock analysis, and that of carbon 

dioxide also when the presence of calcite or cancrinite 

or the altered condition of the rock demands it: 

In this connection a common practice may be briefly 

alluded to, namely, that of deducting water and carbon 

dioXide when the rock is not fresh, calculating the 

remainder to 100 per cent and assuming that the 

result represents the composition of the original unal-· 

tered rock. Tllis assumption is unwarranted and may 

lead to erroneous conclusions, since the processes of 

weathering or alteration do not usually consist in the 

simple addition of water and carbon dioxide, but in 

the assumption of these concomitantly with changes, 

either additive or subtractive, in some or all o{ the 

other components. We are not yet able to determine 

these with much success. Furthermore, by concealing 

the original ~ummation, such a procedure, like any 

recalculation to 100 per cent, unless the original figures 

are given, deprives others of one of the methods of 

judging the value of the analysis. 

RATING OF ANALYSES. 

METHOD OF RATING. 

We have hitherto considered rock analyses from the 

point of view of the analyst. It remains to discuss 

them from that of the petrographer who wishes to 

use the results, and who therefore needs to have some 

means of judging their reliability. For this purpose 

it is necessary to discuss the features of an analysis on 

1 Dittrich, M., Mittbeil. Badischen Geol. Landesanst;, vol. 3, p. 79, 1894. 

2 Hillebrand, W. F., U.S. Geol. Survey Bull. 422, pp. 65 et seq., 1910. 

which this judgment may be based, and it will also be 

convenient to formulate a mode of expressing concisely the general character of an analysis. The ex-

'pression _of the relative worth of an analysis may 

conveniently be called its "rating," in analogy with 

that of commercial houses. 

The user of the analysis must rely on the judgment 

of the collector and· the analyst that the specimen, 

both as to locality and size, correctly represents the 

rock mass, unless some reason appears to the contrary. 

The analysis in itself rarely gives any decisive indication as to this point. 

Analyses of the groundmass of a rock are, however, 

not uncommon, and may be briefly discussed. For 

the general purposes of petrography su,ch analyses are 

· of little use, ·and they have been excluded from the 

present collection. On the other hand, for the solution of certain special problems they may be of great 

value. It must be pointed out, however, that an essential adjunct to their use is a knowledge of the relative 

amounts of the phenocrysts and the groundmass, unless only a knowledge of the composition of, for example, glassy or microaphanitic groundmasses be 

desired. If the purpose is the study of the order of 

crystallization, or some such thing, a knowledge of the 

quantitative relations is indispensable. 

Unfortunately, this knowledge is wanting in most 

cases, quantitative relations being given only in analyses of the portions soluble and insoluble in acid. This 

is ·another example of the prevailingly qualitative way 

of regarding petrological problems. 

It can scarcely be reiterated too often that the 

science of petrography must become quantitative. 

The time has passed when a simple statement of the 

minerals composing a given rock and a description of 

their physical properties will suffice. We need to 

know in addition the relative amounts of the minerals 

as accurately as may be, with their chemical composition, as well as that of the rock itself, derived either 

from chemical analysis or from determination of the 

quantitative mineral composition. Otherwise many 

of the broadest and most fundamental problems in 

petrology will be incapable of solution, and the science 

will still consist of vague gropings after the truth, 

because some of the most essential facts-the quantitative relations----:remain neglected and unknown. 

ACCURACY. 

EVIDENCE AVAILABLE. 

Assuming, therefore, that the analysis is representative as far as the material goes, we have its acclll:'acy 

and its completeness as means of judging its value. 

The features on which this must rest, as far as accuracy 

is concerned, may be stated as follows:

mTERNAL EVIDENCE. 

Agreement with the mode.-It may seem superfluous 

to state· that the chemical analysis of a rock must 

accord with its quantitative mineral composition as 

determined by the 1nicroscope. Such a statement is 

however, necessary, as a study of the many discordant 

results given in the present collection will clearly show. 

The mode of a rock affords the best Ineans of ascertaining whether or not the analyst has done his work 

well. If the composition and the amounts of the minerals present are la1own, the chemical analysis can be 

easily checked by the calculation of the chemical composition from the mineralogical data. The agreement 

need not be exact, and indeed it seldom is except under 

the most favorable conditions, for the measm·ement of 

the amounts of the constituent minerals seen under the 

microscope can not be of the highest order of accuracy, 

an~ assumptions must often be made as to the chemical composition of some of them. But the result will 

often be sufficiently accm·ate to show whether or not 

notable analytical errors have been made. 

In the great majority of cases, however, only the 

roughest kind of quantitative data are either given in 

the descriptions or conveyed by the present rock 

names, if indeed one is fortnnate enough to have any 

kind of quantitative information as to the mineral 

composition vouchsafed him. Here one can detect 

only errors of a flagrant kind and of magnitudes involving several per cent of certain constituents. 

In considering the possibility of any of the errors 

already mentioned, the judgment of the petrographer, 

based on a lmowledge of the chemical composition of 

minerals as well as on his knowledge of analytical 

work, comes into play. All tJhe chemical features 

must be taken into consideration in connection with 

the description, especially in· the absence of exact 

quantitative mineralogical data. 

Thus high alumina (for example, 20 per cent or 

more) in a rock containing 50 per cent or less of silica, 

and even with low magnesia, 'is presumably, but not 

necessarily, due to error in the separation of alumina 

and magnesia. It may be caused by the ilondetenuination of titani'tl.m and phosphorus oxides, or by 

the presence in abun~lance of anorthite or nephelite, 

which will be indicated by correspondingly high .lime 

or soda. Apparently high soda and low potash in 

a so-called orthoclase rock 1nay arise from an imperfect description or incorrect identi£.cation of the feldspar, which may be in reality a soda-orthoclase. 

It must also be borne ill mind that the microscopical may seemingly be at varianc~ with the 

chemical analysis, flJ..ld yet the chemist may be nndeniably correct. This is especially true of analyses 

of very fLne-gramed holocrystalline or hypocrystalline 

rocks, and not infrequently further, more critical, 

microsqopical study will reveal the presence of a 

constituent which has been overlooked but which is 

manifest only after the analysis has indicated its 

existence. . On the other hand, the most careful 

microscopical study may not reveal the ·presence of· 

certain n1inerals, such as quartz or orthoclase, which 

the analysis shows must necessarily be present. These 

undiscovered constituents have been called by Iddings 1 "occult" minerals. This phenomenon is possibly due in part to solid solution. 

An example of this phenoiuenon is afforded. by 

the kulaite of Phrygia, investigated by me, in which 

·the rather abnndant nephelite was at :first overlooked 

in the partly glassy gronndmass and was discovered 

only when repeated careful chemi~a.l work and calculation of the mode showed thn.t it was necessarily 

present. 2 

Other well-known rocks whose chemical analyses 

do not correspond with their microscopical characters 

are the wyomingite and orendite of the Leucite I-Iills. 

In the wyomingite, although modally the only salic 

, .minerals visible are leucite and noselite, the analysis 

shows a large exce.ss of silica. In the orendite there 

is an excess of· alkalies over alumina, with excess 

of silica in .one case. These discrepancies have not 

yet been explained, but there can be no doubt of the 

high degree of accuracy and completeness of the 

analyses 3 or of the mineralogical determinations. 

Another example is the lava of Grenada, West 

Indies, called "augite and~site" in the first collection 

(p. 353), with the remark that the norm and mode 

do not. agree. Prof. Harrison has kindly informed 

me that a reexamination of. the rock shows the 

presence of considerable nephelite in the glassy base 

(analogous to the base of the kulaite) and that it is 

really a nephelite tephrite. 

The norm and mode are seemingly at variance, 

though the analysis is correct, in many basalt's and similar rocks in the dofemane and salfemane classes. The 

norms of many of these rocks show several per cent of 

quartz, though the presence of this is not mentioned in 

their descriptions; or the rock may even carry a considerable amonnt of olivine. Examples may be fonnd 

in andose (II. 5. 3. 4), hessose (II. 5. 4. 4-5), camptonose (III. 5. 3. 4), and auvergnose (III. 5. 4. 4-5). 

If the rock is holocrystalline, .examination often reveals the presence of small amonnts of quartz, generally as micropoikilitic interstitial patches. Quartz 

also occurs thus with olivines, or it may be occult 

in the gronndmass. Here we· are dealing with the 

fact, established by Bowen and Anderson, 4 that olivine 

crystallizes out-that is, it is stable and less solubleat high temperatm·es, leaving the liquid w1th an excess 

of silica, which appears as quartz if the cooling is rapid. 

If the cooling is sufficiently slow, the olivine will be

reabsorbed, forming metasilicate (hypersthene) with 

the excess silica. · 

But unless there is reason to suspect the presence 

of occult minerals, and unless explanation is afforded 

by the description to account for the peculiarities of 

the analysis we may, in general, assume that errors 

have been made and consider the analysis untrustw:orthy in this respect. 

In this connection it may be well to mention that 

the calculation of the norm of a rock is of great use 

in checking an analysis. Though this calculation may 

appear complicated, it is as a rule really simple and 

easily and quickly made. Some knowledge of the 

relations of the standard and the mafic minerals then 

affords a means of making sufficiently close determinations of the mineral molecules to permit a comparison 

of the mode with the analysis. 

It must not be forgotten, even here, that in the absence of a knowledge of the quantitative relations of 

the component minerals very serious analytical errors, 

may not be revealed by calculation of the mode, in 

this or any other way, from the chemical data. The 

error in one or more constituents may amount to sev-: 

eral per cent, and yet a mode cari be calculated which 

will apparently agree with the description or with a 

qualitative microscopical examination. This fact is 

illustrated by my own first analysis of the ciminite of 

Fontana Fiescoli, near Viterbo. 1 The mode, as calculated from this analysis/ seemingly agreed with the 

microscopical examination, although subsequent" investigation and analysis showed that the alumina and 

the magnesia were, respectively, too high and too low 

by about 3 per cent. 3 • 

Of the very common error involved in the incomplete separation of magnesia and alu~ina, perhaps the 

most noteworthy illustration is found in Doelter's 

analyses of the· augitites of the Cape Verde Islands. 

These analyses show 16 to 24 per cent of Al20 3 and 

only 3 to 5 per cent of MgO. It is significant of the 

common ignorance of possible analytical error that Rosenbusch,4 who gives some of them in his table of 

analyses of augitites, merely remarks, '' ueberraschend 

ist ihr hoher Gehalt an Al20 3 bei niedriger MgO." 

Another example of. the error in the separation of 

alumina and n1agnesia is seen in an analysis of the 

essexite of Rongstock, 5 which shows 46.93 per cent of 

silica, 24.19 alumina, and 2.42 magnesia. Part of the 

high alumina is to be ascribed to titanic and phosphoric oxides, which were not determined; but, even 

after due allowance is made for these, it is evident 

that some of the magnesia has been weighed with the 

alumina. This will clearly appear by comparing the 

analysis with two other analyses of the same rock

mass published by Hibsch, 6 which, with 50.50 silica, 

show about 17.85 alumina and 3.35 magnesia. The 

error will be even greater than that indicated by the 

difference between these figures, for the percentages 

of silica and other constituents shown by the analysis 

published by Lang make it certain that his specimen 

was more fernie than those of Hibsch. · 

Another example of this very common error is the 

first analysis of the monchiquite of Shelburne Point, 7 

which gave 18.06 alumina and only 1.12 magnesia, 

although hornblende and olivine are abundant. Attention having been ~ailed to the manifest discrepancy/ it was reanalyzed by another chemist, with a 

result showing 15.87 alumina and 8.32 magnesia. Although this second analysis is by no means· above 

reproach, yet it is sufficiently accurate to show that 

in the first analysis the greater part of the magnesia 

had been precipitated with the alumina. It is also 

almost certain that the two chief errors in the :first 

analyses had been made in the determination of iron 

oxides-one due to the partial oxidation of .the ferrous 

iron in the course of its determination and one involved 

. in the reduction of the solution containing total iron 

by insufficient treatment with hydrogen sulphide. 

The figures for the alkalies also are very improbable 

and indeed the only figures that have any smnblance 

of correctness in this unfortunate exan1ple are those 

for silica, lime, and water. 

An illustration of the incorrect determination of the 

iron oxides, specimens of the rock being taken as a 

basis of judgment, is furnished by the oft-cited· analysis of the syenite of Biella9

, in which the ferric·oxide is 

given as 6. 77 and the ferrous as 2.02. Here there is a 

large excess of ferric oxide over that needed for the 

maximurn possible amount of magnetite or for the 

augitic molecule Fe2 0 3 • (Mg,Fe)O.Si02 , with no· henlatite in the rock to account for it. We are therefore 

forced to conclude that a partial oxidation took place 

in the determination of ferrous oxide, resulting in the 

erroneous figures reported. 

A striking example of the error due . to incomplete 

precipitation of alumina by the sodium-acetate method 

in separating manganese oxide is seen in two analyses 

of the quartz-syenite of Fourche Mountain, Ark.10 One 

analysis gives 13.45 alumina and 5.29 manganous oxide; the other gives, respectively, 18.15 ·and 1.00, the 

sum of the first pair being 18.74 and that of the second 

19.15. Here it is obvious that in the first analysis 

more than 4 per cent of alumina has been weighed as 

"MnO," and it is almost as certain that the 1 per cent 

of the second is too high from the same cause, for the 

rock is very largely felic (feldspathic), and no manganese-bearing 1ninerals are mentioned as present.

RATING OF ANALYSES. 21 

'Two analyses, by different chen1ists, of a solvsbergite of Port Cygnet, Tasn1ania, given by Paul 1 also 

afford examples of the san1e erroi'. One shows 

18.21 Al20 3 and 2.61 :MnO and the other 20.91 Al20 3 

and 0. 77 MnO. 

Exan1ples of error in the determination of the alkalies are furnished by a large series of analyses by Ricciardi of Italian leucite-bearing rocks. One of these 

rocks is a leucite-basanite of Monte Jugo, near :Montefiascone, which, with 48.30 silica and 15.07 ahin1ina, 

shows only 0.94 soda and 1.73 potash. The ammu1t 

of potash reported in the analysis yields but 7.8 per 

cent of leucite and is certainly far too low .. Tllis 

analysis and others of bas ani tes of tllis region by the 

san1e c.hmnist are so lo,\r in alkalies (especially potash) 

that if they were correct the rocks would necessarily 

carry as 1nuch as 10 per cent of quartz, even on the 

assumption that all the bases took their highest possible quota of silica, yielding orthoclase instead of 

leucite and hypersthene instead of olivine. An analysis of the Monte Jugo rock (both specin1ens coming 

unquestionably fron1 the same small quarry) made by 

n1e 2 shows 47.39 Si02 , 14.79 Al20 3, 1.49 Na20, and 

6.93 K20, and yields a norm that is quite consistent 

with the 1neasured mode of the rock. 

What appears to be an instanc3 of the coprecipita-

. tion of lime with alumina (see p. 14) is seen in two 

analyses of ''albite-oligoclase porphyry," given in porphyrite (p. 1015) and 1.5.2.5 (p. 301). Comparison of 

these two makes it appear probable that much of the 

lime in the first was precipitated with the alumina 

through the use of impure ammmlia water, as there is 

by no 1neans suffici(mt to forn1 enough of the anorthite 

molecule to justify the use of the qualifier ''oligoclase." 

Many more examples of incorrect deternlinations 

could be cited, both of these and of_ nearly all other 

constituents, but the above n1ust suffice to point out 

the ilnportanco of close scrutiny of the analytical figures in conjunction with the nlineralogical data. It 

may be mentioned that in none of the analyses cited, 

and indeed in scarcely any analysis containing ·serious 

error, has misgiving been expressed by the petrographer at the tune the analysis was published as to the 

possibility of error, nor has the1~e been any comparison 

of the analysis and the n1ode, ~o matter how apparent 

tho incorrectness. As a result of some experience in 

judging analyses it may be added that in n1anifestly 

poor work the figures for silica and lime are generally 

tho only ones which may be accepted with some degree 

of confidence as to their approximate accuracy. 

Summation.3-Tho summation of a rock anrJysis 

may be a good index to its character, and should 

always be taken into consideration in rating it. In

• Wnshin~:,rton, H. S., Carnegie Inst. Wnshington Pub. 57, p. 124, 1906. 

o This topic has boon discussed by M. l!~. Connor (Cong. gaol. internat., Comptes 

rondus, p. 888, 1914). · 

discussing the limits in the sumnuttion that are consistent with good work, Hillebrn.nd puts the matter very 

olearly 4 in his remarks to the effect that a summation 

somewhat over 100 per cent is better than one below 

100, and he .also assigns tho limits for good work 

as 99.75 and 100.50. With his reasoning and his 

limits I fully concur, though in practice one may be 

lenient and extend the allowable limits to 99.50 and 

100.75 with advantage. 

Though figures that do not fall within those limits 

are good evidence of error, either of omission or commission, in the analysis, the conv-erse is not necessarily 

true-that figures within these limits are proof of correct-results. Several errors n1ay bnlance one another, 

so that the summation may be .very close to 100, although tho analysis is very poor. At tho same time, 

unless indications appear that the analysis is not good, 

it must be taken at its face v-alue. A good summation 

is ev-idence of good analytical work, as far as it goes. 

On the other hand, very low or very high results prove 

that a.n analysis is incorrect in some particulars, or 

possibly as a whole. 

A low summation may be duo to the nondetermination of some constituent, to poor methods, to oaroless 

manipulation, or to all combined. Tho determination 

of watei· by "loss on ignition" tends to yield a low 

total, owing to the oxidation of the ferrous oxide. 

This error will reduce the apparent weight of water 

and may give an unfavorable summation, though the 

other essential constituents may have been accurately 

determined. 

It must also be borne in mind that a low summation 

can not be ascribed to tho nondetormination of a constituent which is precipitated '\tnd weighed with others 

that have been detetminod, such as Ti02 and P20 5 with 

Al20 3, or SrO with CaO. If it is due to incompleteness, the missing constituent must be sought among 

those which are dotermil1ed independently in the 

course of the analysis, such as C02, 803 , Cl, S, or 

BaO. If the deficiency is marked and the description 

of the rook indicates that none of such constituents 

are present, tho low summation must be held as evidence of error somewhere in the analytical work. 

· It may also be noted il1 this c01mection that if ferric 

oxide is calculated as ferrous there will be a deficiency 

of one-tenth of its weight, due to the loss of oxygen. 

The converse is also true. Consequently, if tho iron 

oxides are given only as FeO, tho total of the ·analysis 

will be too low by one-tenth of the amount of ferric 

oxide really present. And, conversely, if they are 

given as ferric oxide tho sum will be too high by oneninth of the ferrous oxide. If the n.mount of either is 

considerable, as it usually is in very femic rocks, the 

nonseparation of iron oxides may thus give rise to an 

apparently poor or an apparently good su.p1mation. 

• Hillebrand, W. F., U.S. Geol. Survey Dull. 422, p. 27, 1910. 
22 CHEMICAL ANALYSES OF IGNEOUS ROCKS. 

In analyses of rocks containing such minerals as 

sodalite, fluorite, much biotite or apatite, pyrite or 

pyrrhotite, in which chlorine, fluorine, or sulphur· has 

been determined, it must be remembered that an equivalent amou.nt of oxygen is to be deducted to get a 

correct result. If the amount of these constituents is 

considerable, an apparently high summation may 

prove to be satisfactory, whereas one that lies within 

the assigned limits may prove to be too low. 

It is possible that a summation higher than that 

allowable may be due to the determination of iron 

oxides as Fe20 3 only, the excess being attributable to 

the excess of oxygen in this over that in FeO, as just 

explained; or it may be due to the fact that no-correction has been made for the oxygen equivalent to 

chlorine, fluorine, or sulphur, also mentioned above. 

In the absence of these two possibilities, the high 

summation can be attributed only to analytical errors, 

such as impure reagents, poor glassware, imperfect 

washing of precipitates, incomplete ignition, or a dusty 

laboratory. No explanation based on incompleteness 

and the nondeterinination of some constituent will 

apply here, and if the excess above .the allowable limit 

is ·considerable the presumption is strong that the 

analytical work was careless. 

Furthermore, it must be remembered that the excess 

or deficiency in all high or low summations can not be 

distributed among all the constituents, for "it is more 

than likely to affect a single determination." 1 

The importance of the summation in determining 

the rating of an analysis lies in the fact that it is itself 

presumptive evidence of good or poor analytical work 

somewhere in or all through the analysis, so tha,t if 

the sum falls wi'thin th<!limits assigned for good work 

the analysis is presumably good,· provided that no 

marked discrepancy. is evident between the analysis 

and the described mode, that the degree of completeness is satisfaotory, and that there is no other evidenoe 

tending to throw doubt on the results. ' 

On the other hand, if the sum is considerably below 

or. above the limits fixed the evidence is much stronger 

than the apparently slight departure of a fraction of · 

1 per cent from the limits might at first sight seem to 

indicate, as it shows that some error or errors have been 

made, and that· consequently the character of the 

analytical work as a whole is open to suspicion. Thus 

a summation of 99.00 1nay be due to the no.ndetermination of some constituent, but in the absence of evi~ 

dence to this effect we can only conclude that some 

error has been made. This departure of but one-half 

of 1 per cent from the limit of the standard of good 

work may affect either the silica or the alumina, the 

constituents that are present in largest amount, and 

may not seriously affect the value of the analysis; or 

it may affect some constituent present in less amount, 

1 Hillebrand, W.:F., U.S. Geol. Survey Bull. 422, p. 28,1910. Cf. Appendix to 

Fresenius's Quantitative Analysis. 

and thus be of relatively greater ·importance; or it 

may be distributed among several constituents. We 

have no n1eans of deciding the nature of the errors in 

most of such analyses, but we must conclude that, as the 

work is certainly incorrect, even to so small an extent, 

in some particular, it may be incorrect in others, and 

possibly all through. 

Summations somewhat above or below the limits 

fixed are excusable in analyses of complex minerals or 

of meteorites if the material available for analysis is 

scanty or the analytical processes are especially complex or difficult, and the allowable possible limits of 

error are consequently considerably greater than that 

fixed for analyses of igneous rocks. It must also be 

remembered that the analyses of minerals may be 

checked by their agreement with the known calculated chemical composition. For most analyses of 

rocks, on the other hand, we have no such check, as 

adequately exact data as to the relative amounts of 

the constituent n1inerals are seldom given. If, therefore, the analysis of a rock is satisfactorily complete, 

there is no excuse, as Dr. Hillebrand remarks, for a 

summation that does not fall within the somewhat 

liberal limits here assigned. 

In a series of analyses by the same analyst, some of 

the analyses 1nay show summations within the acceptable limits, whereas those of others may be as high as 

102 or as low as 98 (an actual case). The bad summations in such a series of analyses indicate serious errors 

in the whole series and lead one to reject those analyses of the series whose summations are apparently acceptable, for one is justified in assum~ng that the good 

summations resul~ from the chance balancmg of errors. 

In stating analyses it is the almost universal practice to use two places of decimals, a practice justified 

because the last figure, though not very significant, 

expresses the lin1it of accuracy in weighing (0.01 milligram), and because of uniformity. Also, when the 

amount of any constituent is less than 1 per cent, the 

use of but one decimal is clearly not adequate. The 

use of three deci1nals is unjustifiable, for it implies a 

greater degree of accuracy than can be reached in 

practice, and my experience sho·ws that most of the 

analyses thus stated clearly afford other internal evidence of unsatisfactory work. . 

EXTERNAL EVIDENCE. 

Analyst.-Among the factors that may come under 

the head ·of "external evidence" the analyst himself is 

the most important, but for several reasons this factor 

can be used only with caution and subsidiary to other 

criteria. That is, the analyst is to be judged by his 

work rather than the work by the analyst. 2 Though 

as a general rule it may be said that the work of a beginner will probably not be so good as that of an expe2 H. H. Robinson, in a recent paper (Am. Jour. Sci., vol. 41, p. 257, 1916), dis· 

cusses the work oi different analysts on the basis of the summations of their 

analyses. 
RATING OF ANALYSES .. 23 

rienced analyst, yet exceptions occur; so that we 

must not be too sweeping in our judgment of the 

annJ.yses of a student unless they show distinct signs 

of poor work. On th~ other hand, an experienced 

analyst n1ay turn out analyses that are n1anifestly 

incorrect, possibly because of the mnployment of poor 

methods or poor reagents, so. that in the appraisal of 

these the long experience of the analyst will count for 

little, for a rock analysis 1nade by hin1 which can not 

be checked by comparison with .the mode will be 

looked on with misgiving. 

A word n1ay be said of the analytical work of women: 

I know of but three 1 who have made any considerable 

number of rock analyses, and I have found the work 

of nJ.l to be uniformly good. It would seem that analytical work is especially well adavted to fe1ninine 

characteristics, and that rock analysis could be advantageously undertaken by women . 

..i11ethods.-The methods en1ployed in 1naking an 

annJ.ysis are seldom stated· and are therefore not often 

available as a means of judging its value. When they 

are known, however, a petrographer who is experienced 

in rock annJ.ysis can detern1ine the extent to which they 

may affect the vnJ.ue of the analysis. 

· Indirect evidence.-Evidence of an indirect nature is 

sometimes ·afforded by analyses of the sa1ne or similar 

rocks by other annJ.ysts, which lllay either corroborate 

or disc~·edit an annJ.ysis under consideration. Also, as 

noted above, if some analyses of a series show evident 

signs of error the presumption is s.trong that the others 

are also subject to the same error unless they can be. 

checked by con1parison with the 1node. 

001\IPJ. .. ETENESS. 

In order to ascertain fully and accurately the composition of a rock the exact amount of every one ~fits 

constituents n1ust be detennined, so that, in general, 

the 1nore constituents detel'lnined the more closely will 

the analysis represent the con1positi~n of the rock. 

This statement, however, is subject to the limitations 

that so.me rocks are of si1nple c01nposition, containing 

only n. few chemical constituents, and that the statement of figures for all these possible constituents is no 

evidence thn.t they have been correctly determined. 

Assuming, however, that the analysis is accurate and 

that the rock is of complex c01nposition, as it usually 

is, we 1nay briefly discuss the relative i1nportance of 

the -various constituents in the rating of analyses. 

Speaking generally, and bem·ing in mind the possible 

·occurrence of rocks containing large an1om1ts of Ininet·als that are regarded as rare, or that are usually 

only sparingly present, it n1ay be· said that in the 

most satisfactory work every constituent should be 

determined that is present in amount greater than 

traces, as already defined, or the knowledge of whose 

absence or presence, even in 1ninute quantity, is essen-

tial to our study of ·the 1·ock or to the object of the 

investigation. 

This determination will include· the nine main constituents that are almost universally present and whose 

absence would be a matter of interest; that is, Si021 

Al20 3 , Fe20 3 , FeO, :MgO, CaO, Na20, K20, and 1120. 

The iron oxides should be determined separately, or 

the absence of one or the other should be shown, even 

in analyses of the most salic rocks, though it must be 

borne in mind that the influence of this separate determination increases with increase of the femio components. Likewise, the nJ.kalies should always be · 

determined, of course separately, and even in the most 

fernie rocks their presence in traces or their complete 

absence should be definitely proved. CaO and MgO 

should also be determined, even though they exist 

actually as traces, as defined above. H20 should, in 

general, be determined directly, and not by "loss on 

ignition," but the distinction between that below and 

that above 110° is not usually essentinJ., yet is desirable .. 

C02 should, however, be determined if the rock is not 

fresh,' or if ·calcite or cancrinite be present. 

It is next of interest to know the amounts of the 

so-called minor constituents likely to he present in 

notable amount, including Ti02 and P20 5 iri nearly all · 

rocks, except the most salic ones, Cl andJ S03 in rocks 

containing sodalite, noselite, or haiiyne, S in a good 

many fernie rocks, Zr02 in rocks with nephelite, much 

eudialyte, .or zircon, and in alkalic, especially sodic, 

rocks in general, and Cr20 3 and NiO in many dofemanes and perfmnanes. It is also well to determine 

BaO in alkalic and especially potassic rocks. 

Of course any one of these may at times assume the 

importance. of ·one of the ni~~ main constituents, as 

Ti02 in nelsonite and ores produoed by segregation ·or 

differentiation, Cl and S03 in such rocks as taimyrite, 

tawite, and haiiynophyre, P20 5 in the apatite syenites 

of Finlm~d and nelsonites,' or Cr20 3 in many dunites. 

Assun1ing that, as usual, the minor constituents are 

present in only s1nall amounts, the n1ost noteworthy 

are Ti02 and P20 5 , especially the former. Both are 

almost invariably present and are also of special importance, because their estimati01i affects that ·of 

Al20 3 , as already explained. In fact, on this account 

these two should always be determined in any analysis 

that is to be considered gooc~. l\1n0, although. also 

nearly always present, is of comparatively little consequence, and its detel'lnination or nondetennination 

should not affect seriously the rating of the analysis. 

Of the other generally rare or very 1ninor constituents, such as Zr02 , Cr20 3 , NiO, BaO, SrO, little need, 

be said. Except when they assume an in1portant 

role, as already mentioned, they scarcely affect the 

value of an analysis for general purposes. Still, since 

they are or 1nay be of great value for the study of 

certain broad and as ye~ undeveloped problems, and 

as their determination, other things being equal, is 
24 CHEMICAL ANALYSES OF IGNEOUS ROCKS. 

evidence of careful and thorough analytical work, 

analyses in which they are reported must be rated 

higher than those in which they· do not appear. 

RATING ADOPTED IN THE' TABLES. .. We come now to the practical application of the· 

foregoing ren1arks-that is, to a concise expression of 

our judgment of the .value .of any given analysis, 

based on the features described. We have been 

accustomed to express our judgn1ent in a rough way 

by calling analyses good, or poo:r, or bad. ·_: But there 

seems to be a need of making these tenns more precise, of defining their meaning 1nore exactly. 

As a prelin1inary, the fact must be recognized that 

though the features discussed permit a fajrly accurate 

judgment on most analyses, some or all of these features are not invariably available and an ~nalysis 

must often be taken, so to speak, at its face value. 

· Thus it frequently happens, especially with the 

prevalent almost purely qualitative descriptions, that we 

can form little or no estimate of the cor,respondence of 

the analysis with the mode. In a gabbro, for instance, 

of which it is merely known that the constituent nlinerals are labradorite, augite, and magnetite, the anl:l,lysis 

may show high Al20 3 and low MgO. This showing 

may be due to the common error iri. the separation 

of these two; or, again, it may be due to· the fact that 

the rock is very salic, so that anorthite is abundant 

and the mafic 1ninerals present in small amo.unt, 

though the rock would be called a gabbro,' equally. 

with a very fernie one, in the .current vague qualitative systems. In the first case the analysis would 

not and in the second case it would correspond with 

the mode, and the analysis would be, respectively, 

either incorrect or correct. But in the absence of 

some evidence to determine the matter, such as an 

indication of. the quantitative relations of the two 

minerals _in the description, we should have no means 

of deciding the question provided that CaO was high 

enough, with the alkalies, to satisfy the Al20 3, and if 

the analysis were otherwise good we should scarcely 

be justified in rejecting it on this account. 

We must also make the general assumptions, in the 

absence of e:vidence to the contrary, that the material 

analyzed i13 representative of the rock mass and that 

the analyst is ·competent and the methods mnployed 

are reliable. 

Admitting these serious difficulties in judging many 

analyses and the fact that any such concise characterization is necessarily to some extent arbitrary 

or subjective, I venture to propose and have used 

throughout this collection the following practical 

method of expressing the rating of analyses. 

The method is closely analogous to that of Dun 

and of· Bradstreet in rating the ·credit of mercantile 

houses in the United States, which, indeed, suggested 

the present form of the scheme. In commercia.! 

rating the credit of a firm is dependent on two factors-the am9unt of capital invested or at command 

and the personal character and reputation of the 

individuals. The rating or credit will be high as the 

personal character and the capital both approach the 

inaxi1nun1. 

Following out this analogy, our judgment of analyses 

is dependent on two factors-the accuracy and . the 

completeness. For most of the purposes for which 

rock analyses are used each of these n1ay compensate 

the other to a certain extent. ·Thus if the analysis is 

not very complete this fault may be partly compensated for by the accuracy of the d'etern1inations 

which have been made, and, conversely, if the accuracy of some of the determinations is· not entirely 

satisfactory a complete determination of all the COI1-

stituents may partly make up foi· it. This, of course, 

should be within reasonable limits. Furthennore, the 

higher the standard of each factor the n1ore valuable 

will be the analysis. 

To express the degree of accuracy the letters A, B, 

C, D are used, and to express the degree of completeness the fi~ures 1, 2, 3, 4. These are used i11 combinations of a letter and a figure, the letter preceding, 

since, in general, tha degree of accuracy is more 

importt:.:.t.lt than that of completeness. The bases on 

which these are assigned are as follows, the lin1itations 

and the frequently arbitrary character of the scheme 

being understood: 

A is used when the analysis gives evidence of the 

highest degree of accuracy-that is, when it corresponds weU with the mode and when the summation 

is between the limits 99.50 and 100.75. When the 

analyst is of the first rank and when the methods are 

known to be of the best, these facts constitute additional reasons for the assignment of this letter. It 

must be understood, however, that in rating the 

analyses in the collection I have usually refrained 

from considering the personal competence of the 

analyst, as tliis is often a difficult and always a delicate 

matter. .So, except when the 1nethods or general 

results were known to be not very reliable or positively bad, I have generally used only the impersonal 

features of each analysis in deciding its rating. 

B is used when the analysis and the mode correspond and when the sumn1ation is between 99.50 

and 99, or between 100.75 and 101.25. Due allowance must, however, be made here, as elsewhere, in 

considering low summations, for the effect of the nondetermination of certain constituents, as already 

explained, and in considering high summations for the 

correction to be applied in the presence of Cl or S. 

C is. used when the analysis corresponds fairly well 

to Or varies but little from the mode and if the SUlll is 

between 99 and 98.50 or between 101.25 and 101.75. 

D is used when the analysis varies decidedly from 

the 1node in any essential particular, or when the sum 
R-ATING ADOPTED I_N. THE TABLES. 25 

is below 98.50 or above 101.75. It also applies when 

the 1nethods used for detern1ining in1portant constituents are known to be bad, or when an analysis, apparently good, is Jnade up by con1bining parts or the 

whole of two or n1ore poor analyses. 

Analys0s stated in one or three decin1al places have 

been consistently rated 1 degree less as Tegards accu-

·racy than they would have been had they been. stated 

in two decimals, as it has been found that they are generally of inferior quality. Analyses stated in only one 

decimal place fail to confor1n with the weighings of 

the analysis and do not adequately show the amotu1ts 

of the minor constituents. For these and other reasons 

I differ with the recent usage of Prof. Milch.1 This has 

been discussed elsewhere. 2 

1 is assigned when the analysis is perfectly or 

nearly complete, as when, in addition to ·all the .n1ain 

constituents and those of secondary itnportance, 

Zr02 , Cr20 3 , NiO, BaO, SrO, and the liEe, or several 

of thmn, are determined. in rocks not containing notable 

amounts of n1inerals having these as essential components. In general :MnO should be detern1ined for this 

rating, but not necessarily, and the saJ.ne is true of the 

separate determinatioi1 of combined and hygroscopic 

water, though the detenninatioJl ·of water as "loss on 

ignition" renders the application of this rating doubtful. The iron oxides 1nust be separately determined 

in all analyses to which this figure can be applied. 

2 will be used when all the 1nain.constituents, including both oxides of iron, have been determined, as well 

as the constituents of secondary in1porta11ce, including 

Ti02 and P20 5 in neaJ.·ly all rocks, Cl and 803 in those 

that contain abundant minerals of the socialite group, 

and so on, as has been explained. The minor constituents, Zr02 , BaO, etc., are not determined in analyses 

rated with this figure. 2 will be used also for analyses 

of very snlic rocks in which the iron oxides are present 

in snuul amount (up to about 2 per cant), but have 

not been separated, and which are otherwise.so complete as to fall under 1. 

3 applies to analyses in which the main constituents, 

including both oxides of iron, have been determined, 

but not Ti02 , P20 5 , Cl, etc. (or the minor constituents), 

unless 1ninerals rich in these are so abundant, or, as 

regaJ.·ds Ti02, the rock is so fen1ic, as to n1ake their estimation of the saJ.ne in1j>0rtance as that of the main 

constituents. 3 also includes- analyses of rocks low 

in iron oxides, in which these have not been separated, 

but which are otherwise complete according to the 

requir01nents of 2. · 

4 is to be assigned to analyses of all rocks except 

those very low in the iron oxides when these oxides 

ha,7"e not been sepaJ.·ated, when the alkalies or other 

constituents are d~termined by difference from 100 

per cent, when the alkalies are not separated, when 

I :Milch, J ... , N.J. D. B., 15, p. 111 (note), 1902. 

~Washington, H. S., Chemical analysis of rocks, p. 30, New York, 1910. 

any constituent of the first importance is not determined, when the analysis has been made of ignited 

material (not including drying at 110°), or when it is 

given, without the original figures, as having been 

recalculated on a water or carbonic-acid free basis. 

Under the working plan already described, one of 

these factors compensates for the other to a certain 

extent. Thus a less degree of completeness is conlpensated for by a greater degree of acctrracy. We would 

then judge, for exaJ.nple, an analysis of rating A2 and 

one of rating B1 to be of about equal value for many 

purposes. This is, confessedly, only true within limits 

and must be used with judgment and with a recognition of its empirical character. 

To express, then, the various ratings of .equal value, 

we can ·employ five series of terms as follows: Excellent or first rate, good or second rate, fair or third rate, 

poor or fourth rate, and bad or fifth rate. Their meanings, in terms of the symbols chosen, will be seen in the 

subjoined table, ratings of the same value falling on 

the saJ.ne horizon tal line. 

First rate (I) ..... Al ........ ......... Excellent.) 

Second rate (II~ .. A2· Bl ......... Good. Superior. 

Third rate (III .. A3 B2 01 Fair. 

Fourth rate (IV) . A4 B3 02 Dl Poor. ( ..... B4 03 D2 )Inferior. Fifth rate (V) .... -···· 04 D3 )Bad D4 

In other words, analyses of the rating A1-those 

that are perfectly satisfactory both as to accuracy and 

completeness-would be called "excellent" or ":first 

rate (I)," the two terms being synonymous. An 

analysis to which is assigned the rating either A2 or 

B1 would be spoken of as "good" or "sec~:md rate 

(II)''; one with either of the three ratings A3, B2, or 

C1 would be called "fair" or "third rate (III)"; one 

with the rating A4, B3, C2, or D1 would be ".poor" 

or ''fourth rate (IV) ''; and one worse than these 

would be "bad" or "fifth rate (V)." 

In any case, it must be remembered that accuracy 

should count rather more than completeness, since 

often an approximate correction can be made for 

constituents not determined, as for Ti02 and P 20 5 

affecting Al20 3 • Consequently, though of the smne 

general rating, an analysis rated as A2 is worth rather 

n1ore than one rated as B1, and those rated as A3, B2, 

and C1 should be similarly appraised in the order of 

merit. 

As a mnemonic convenience it may be useful to 

note that, if the letter indicating accuracy in any 

rating be replaced by the figure representi11g its phwe 

in the alphabet, the sum of this figure and the figure 

indicati11g completeness will be one unit greater 

than the rating of the analysis. Thus in a first-rate 

analysis, of rating A1, the sum will be 2; in a secondrate analysis, of rating A2 or B 1, the sum will be 3; in a 
26 CHEMICAL ANALYSES OF IGNEOUS ROCKS. 

third-rate one, of rating A3, B2, or 01, the sum win 

be 4. In the rating of fifth-rate analyses, however, 

the sum may be greater than 6, as for instance, in 

the rating D4, where it wiU be 8. 

As will be seen presently, analyses of the first three 

ratings-that is, excellent, good, or fair-are worthy 

of use in petrological discussions, whereas those of 

the fourth or fifth rate-that is, poor or bad-are of 

little or no use. In order to be able to distinguish 

between the two it will be well to have some short 

terms expressing the difference. It is suggested, there-· 

fore, that excellent, good, and fair analyses be spoken 

of collectively as superior, and that poor and bad ones 

be called inferior. 

. It may be desirable to indicate a higher degree of 

accuracy or completeness than is generally implied by 

A and 1. Thus, though A will apply to the general 

run of excellently accurate analyses, we might wish· 

to distinguish some of a still higher order~ as the best 

of those which Drs. Hillebrand, Stokes, Steiger, and 

Mingaye have made. These may be distinguished by 

the use of A*. Similarly it may be useful to discrimi- · 

nate analyses having the completeness found in Hillebrand's analyses of the rocks of the Leucite Hills, in 

which everything possibly present has been determined, from those in which some but not all of the 

rarer constituents have been estimated. This discrimination would involve the use of 1 *. A combination of A* and 1 * might be called ''perfect," the 

word being used subject to human limitations. There 

does not yet seem to be much need of this distinction, 

though it will undoubtedly be more needed in the 

future than a discrimination between degrees of bad .. 

ness. 

It should be remembered that these ratings indicate the general character of an analysis. Some features may justify us in calling an analysis as a whole 

either poor or bad, and yet it will be of use in a limited 

way. Thus, the iron oxides may not be separated, 

or the common error may be made in. regard to 

alumina and magnesia, so that the analysis must be 

rated as fourth or fifth rate, taken as a whole, yet 

the lime and alkalies, for instance, inay have been 

correctly determined, as well as the silica, so that 

for purposes in which only these determinations are 

needed the analysis may be useful to this extent. 

But, notwithstanding this, in view of its evident errors, 

the analysis can not be regarded as satisfactory. 

The question now arises as to what ratings are of 

practical use. Leaving. out of account conditions· 

such as those just mentioned, in which utility attaches 

to some single· determinations, it may be held that, 

for general purposes, only first or second rate (excellent or good) analyses should be countenanced or used 

by petrographers. The high standard set by the 

chemists of the United States Geological Survey 

should be adopted by all, and the chemical side of 

petrology should be established on as firm and satisfactory a basis as the microscopical. 

At the same time an otherwise good analysis in 

which the more important of the 1ninor constituents 

have not been determined, ·such as Ti02 and P20 5 , 

.niay be of use for some purposes, as for the classification of the rock. Third-rate or." fair" analyses may 

therefore be considered usable, especially if of. high 

rate as to accuracy, since in many of them approximate corrections may be applied for constituents 

which have not been determined. 

Excellent, good, and fair- (superior) analyses may 

therefore be considered usable, but poor or bad 

(inferior) analyses should be rejected in any inquiry 

or discussion, unless the only question at issue is the 

elucidation of a special point for which some of the 

reliable determinations may serve. 

THE TA~LES. 

DIVISION INTO PARTS. 

It was desired to arrange the analyses embraced in 

the collection according to the quantitative system of 

classification. Fpr most analyses such an arrangement 

was perfectly feasible, but a critical study of all of 

them showed that only a part ·could or should be 

thus arranged. In a surprisingly large number the 

iron oxides, for example, had not been determined. 

Though this is of ·comparatively small importance in 

analyses of persalanes, where these constituents fonn 

only 1 or 2 per cent, it becomes a most serious matter 

in analyses o'f other classes of rocks. Indeed, ·if the 

iron oxides amount to more 'than about 2 per cent 

and are not determined separately it is generally 

impossible to classify the rock with certainty, for 

some assumption must be made as to the real state 

of oxidation of the iron, and this !1Ssumption 1nay 

not accord with the facts. 

If the iron is assumed to be present as ferric oxide 

alone, this must generally be calculated as hematite to 

find the norm, thus freeing an an1ount of silica equivalent to the ferrous iron, which will alter the relative 

amqunts of the other minerals, changing lenads into· 

polysilicate feldspar ~r olivine into hypersthene. On 

the other hand, if all the iron is assumed to be ferrous, 

which is the rule followed for the sake of uniformity, 

an amount of silica will be needed which would not be 

used if part of the iron were ferric, and this would have 

the reverse effect on the other normative minerals to 

that just mentioned. It will, of course, probably be 

equally at variance with the true composition of the 

rock to make any other intermediate assumption-for 

instance, that ferric and ferrous oxides are present in 

equal molecular amount, the iron being thus assumed 

to be only in the form of magnetite. 

We are therefore compelled to reject nearly all such 

analyses for the purpose of classifying the rocks of 
THE TABLES. . 27 

which they have been 1nade, as has been already stated. 1 

Along with thmn must go a large number in which it 

is certain that the alumina is much too' high and the 

1nagnesia correspondingly low, or in which we know that 

there 1nust be a very notable amount (several pei· cent) 

of Ti02 which has not been detern1ined, and which 

consequently serves to raise the apparent amount of 

alumina. In these analyses the salic lime, and therefore the norn1ative anorthite, ·will be too high and thB 

classificatory position of the rock conseque~tly false. 

A ve~·y large nun1ber of analyses ~re obviously so 

bad in other respects that they are almost or wholly · 

worthless. It is needless to cite exan1ples, for they 

may be found throughout the whole of Part IV. 

Al1alyses of tuffs and of rocks so badly decomposed 

that the analysed do not represent their original composition were also found in abundance. Though 

many of these are analyses of the highest ratings, yet 

they were obviously of no use for purposes of classification, and hence could not logically be correlated with 

analyses of n1assive or unaltered rocks. 

Analyses of volcanic ashes offer a peculiar :problem. 

In Professional Paper 14 they were relegated to Part 

II, on thQ grou~1d that the ·ashes presumably undergo 

a sorting or winnowing in their progress through the 

air, so that their eventual con1position as analyzed 

would be more or less adventitious and not be representative of that at the place of ejection. Further consideration and study of n1any analyses of ash, however, has 

led 1ne to assign less weight to the influence. of such a 

process, especially when the ashes are collected near 

the eruptive center, and consequently in this paper 

analyses of volcanic ashes are included in Part I if of 

superior quality, not obviously dec01nposed, and not 

~oliected very far fr01n the place of eruption .. 

In Professional Paper 14 all the analyses were 

placed in two parts. Pm1

t I conta~ed all the superior 

analyses (ratings I, II, and III) of fresh rocks and 

a few analyses of inferior quality or of rocks that were 

not quite fresh, which were inserted chiefly because 

they "were deen1ed to be of especial interest and 

importance or \Vere almost the only exan1ples available 

for illustrating the chemical and mineralogical composition of the divisions into which they seemed to fall." 

In Part· II were placed the inferior analyses and 

analyses of altered rocks, tuffs, etc., even if of the 

highest rating, except the few admitted to Part I. 

This arrangement seemed to be unjust to tP,e makers 

·Of excellent or good analyses of altered rocks, for, 

though the rating syn1bols were given, the analyses 

·were naturally associated with those which were bad. 

There were also included in Part II a number of 

analyses that were good as to most of the constituents, 

but that could not be classified because of the nont Cross, \Vhitmnn, Iddings, J. P., Pirsson, L. V., Washington, H. S., Jour. 

Ooology, vol. 10, p. 6<16, 1902; nlso The quantitative classificntion of igneous rocks, 

·p. 190, 1903. 

determination of some one constituent, most often 

that of both irion oxides, though they were usable 

otherwise for many puTposes. 

It has therefore been decided to arrange the analyses 

in four parts, which will be constituted as follows: 

In Part I are placed all the superior analyses of fresh 

rocks-those which are excellent, good, and fair-except those which can not be properly classified in the 

quantitative system because of the nondetermination 

of one constituent. It does not include analyses of 

any tuffs or of rocks which are more than very slightly 

altered (weathered or metamorphosed). In general 

the presence of more than about 3 per cent of water 

in an analysis has ~xcluded it from this part, except 

analyses of evidently fresh glassy pitchstones and 

like rocks or of analcite rocks (such as monchiquites), 

where this mineral is considered to be of primary 

origin. Also, in general, the presence of one-half 

of 1 per cent or more of carbon dioxide has excluded 

the analysis from this part, except a few analyses in 

~hich calcite is apparently taken from surrounding 

limestones, as in some Ontario rocks, and in which 

it has been allowed for and not brought into the 

norm; or unless cancrinite is apparently primary. 

Analyses of rocks in the dedcriptions of which chlorite, 

epidote, zeolites, kaolinized feldspars, or other alteration minerals are mentioned as present in more than 

very small amounts are of course excluded. Analyses 

of volcanic ash are included, in general, if of superior 

quality, not obviously decomposed, and not collected 

very far from the volcano. 

The number of analyses has increased so greatly that 

the qualifications for entering Part I have been much 

stricter than those requu·ed in Professional Paper 14, 

and a great many that were put in this part must now 

be sought elsewhere, On· the other hand, a few have 

been transferred from Part II of the first edition to 

Part I of this. In spite of this increased strictness, 

ahnost every systematic division in Part I now 

contains several times as many analyses as before. 

In Part II are placed the superior analyses-generally good or fair-which were not deemed to be properly classifiable in the quantitative system, because 

of the nondetermination of some one constituent. 

Most of them are placed here because of the non-· 

determination of one of the iron oxides, with analyses 

of a few of the more fernie rocks in which Ti02 was not 

determined. Analyses of the more fernie rocks which 

do not show both iron oxides and titanium dioxide 

have been placed .i.:n Part IV. They are arranged ill 

the order followed in Zirkel's Lehrbuch, soniewhat 

modified to accord with Iddings's "Igneous rocks." 

In Part III are placed the superior analyses of tuffs 

and of weathered or otherwise altered rocks and 

analyses of some ashes. When possible a reference is 

given in the last column headed "Remarks" to the 

analysis of the fresh form of the altered rock. · 
28 CHEMICAL ANALYSES OF IGNEOUS ROCKS. 

In Part IV are placed nearly all the analyses deemed 

to be poor or bad. This part and Part III embrace 

many analyses formerly placed in Part I. 

BASIS OF ARRANGEMENT OF ANALYSES. 

ATTEMPTED USE OF CURRENT PETROGRAPHIC SYSTEM. 

"When this collection was first started, more than 

15 years ago, the analyses were c.lassified ·according to the system of Rosenbusch. Generally the. 

name given by the author to the rock was adopted, · 

but many rocks seemed to me to have been wrongly 

nan1<::d, so I took the liberty of renaming them, but 

put the author's name in brackets. As the collection 

progressed this renaming became frequent, as is by 

no n1eans surprising in view of the loose and often 

c?ntradictory principles, the subjective and qualita- · 

tive character, and the vague definitions prevalent in 

~he sys~ems in v~g~e. It furnished a most striking 

Illustratwn of thmr illogical, inconsistent, and unsatis-. 

fac~ory cha~acte~, ~nd was a most. cogent argument 

against thmr continued use. It indicated, indeed 

that there was in reality no one system to which 

one could turn for guidance, but that each petrographer had set up his own standards to some extent 

made his own definition of many of the terms i~ use, ~r assigned his own limits to them, which might 

or might not correspond with those .of others-in· a 

word, had partially made his own classification and 

n?menclature. ·Each was a hodgepodge, made up of 

bits taken from this or that authority or evolved 

from the individual author's own ideas. There was 

seldom if ever any broad principle which one could 

apply throughout, and the result was a clashing of 

principles, inconsistencies everywhere, and a lack of 

harmonious and even development. If a petrographer 

had been working on a· certain group of rocks his 

classifica~ion in that group would be very detailed, 

whereas In other groups the names he gave would be 

few, and the classification of some authority would be 

used with no critical estimate of its applicability and 

no thought of its logical consistency with the other 

more detailed and familiar parts of the scheme. 

Everyone has recognized this state of affairs more 

or less ~learly; but it is forced most strongly upon one 

who makes a large collection of rock analyses and a 

careful comparison between the descriptions and 

analyses and the names applied to rocks by the different writers. 

Roth 1 has expressed somewhat similar views and 

is inclined to think that no one system will ev~r receive general acceptance. I am less pessimistic, for I 

1 Roth, J., Chern. Geologie, vol. 2, p. 41, 1883. Cf. Cross, Whitman, Jour. Geology, vol. 10, p. 4i3, 1902 .. 

regard the lack of any universally adopted system of 

classification as due less to difficulties caused by the 

characters of the rocks than to the general lack of 

appreciation of the necessity for logical and consistent 

principles, and to a natural disposition to patch up the 

old r~ther than to substitute something totally ne'Y, 

even If better. 

ADOPTION OF THE . QUANTITATIVE SYSTEM. 

While this early collection was being made I became 

interested, with Cross, Iddings, and Pmson, in the 

working out of the system of classification and nomenclature of igneous rocks which has been proposed by 

us. In the course of this work the growing collection 

of analyses was continually referred to, the modes of 

many of the analyses were calculated, and they were 

r~~rranged from time to time to test the various propositwns or suggested lines o.f classification until agreement with any system at present in use was lost. 

After having arrived substantially at the system 

of classification which we finally adopted, we saw that 

the collection if arranged in accordance with .this 

system would not only be its best exponent, but would 

be an indispensable foundation for purposes of nomenclature, the ~onsideration of which was· taken up only 

after· the main features of the classification had been 

disposed of. 

The collection was therefore finally made as complete as possible and arranged in accordance with the 

new system,2 and we decided to publish it in that form. 

The same course has been followed in this edition. 

FEATURES OF THE TABLES. 

. Geographic ~rrangement.-In eaoh of the subrangs 

m Part I and 1n eaoh of the rock groups in the other 

parts the arrangement is geographio. The primary 

step is by oontinents, North and South Amerioa ooming first, then in order, Europe, Africa, Asia (includinO' 

the Malay Archipelago), Australia and New Zealand0 

Polynesia and the scattered islands of the Pacific In~ ~an, and South Atlantic ooeans, and finally An~arc­ twa. The States and minor divisions are arranged in 

zones running from north to south (except in Germany, where it is from west to east), and in a rough 

way looalities have the same general order. At any 

one locality the analyses are arranged aocording .to 

decrease in silica, or, if this should be the same in two 

analyses, aocotding to deoreasing alumina. 

The general scheme is shown in the annexed list. 

The soattered islands are not included. Though this 

order is followed in general, yet in places it has been 

inadvertently departed from.

In this connection attention may be called to the 

striking gaps in our knowledge of the chemistry of the 

igneous rocks of v-arious parts of the globe. Though 

s01ne countries hav-e been very thoroughly studied in 

this way and are represented by numerous superior 

analyses, others have been n1uch neglected or are quite 

unrepresented. The long line of gigantic Andean 

volcanoes show an inadequate number of analyses, 

and most of these of not very .satisfactory quality. 

Other very '\vell known regions, of which the Eifel, 

Siebengebirge, Schemnitz, and Etna may be Inentioned, are represented by few analyses other than 

those of early date,. so that we know little about 

them chemically. The vast expanses of India, Tibet, 

and China are represented by a surprisingly small 

number of analyses, and few of these are very good. 

Not a single analysis was found of the igneous rocks 

of such large and well-known islands as Cuba, Porto 

Rico, and Jamaica. 

}lumbering of analyses.-For purposes of referenee 

each analysis is numbered, the numbering beginning 
30 CHEMICAL ANALYSES OF IGNEOUS ROCKS. 

anew with each subrang in Part I and with each 

general group in the other parts. ·In referring to any 

given analysis thenumberwill be used with the symbol,. 

not with the subrang name, as in the first edition. The 

number is repeated on the right-hand page. · 

Rating of analyses.-With the number is given the 

rating assigned to the analysis by me, according to 

the principles already described. The letters and 

numbers which indicate the degree of accuracy and 

completeness are given, with a Roman numeral to 

express its general rating, as shown on page 25. Thus, 

A 1. I means that the analysis is excellent or first rate, 

being highly accurate and complete, A 3. III that· it is 

fair or third rate, being of high accuracy, but only 

moderate as to completeness. 

The rating of some analyses has been difficult. The 

criteria for judgment outside of the analysis itself are 

often lacking or insufficient, but I have endeavored to 

be judicial and unprejudiced, and the rating generally 

expresses my frank opinion of the value of the analysis. 

Where I have had serious doubt as to the accuracy of 

the work, yet have been unable to assign any definite 

reason for the doubt, I have settled it in. favor of the 

analyst, so that I look with suspicion on some analyses 

that are here rated as superior and that appear in 

Part I, though I have no· positive proof of their 

inferiority. An interrogation point ( ~) after a symbol . 

indicates that the rating assigned is one degree higher 

than that which I suspect it deserves. 

I 'may repeat that each individual analysis has been 

the object of careful consideration and that many of 

the ratings given in the first edition have been revised 

in the light of increased knowledge, so that I feel con-· 

fident of the correctness, according to the standards 

adopted, of nearly all of them. 

Time was lacking for a critical study of the num-. 

ber of analyses assigned to each of the several ratings, and of the progressive improvement in quality-. 

such a study as was made for Professional Papers 14 

(p. 65) and 28 (p. 15). This study will be made, 

however, and will form the subject of a separate paper. 

A general survey indicates, as would be expected, 

that the improvement since 1900 has been steady, so 

that probably 75 or possibly 80 per cent ·of the analyses 

made since then are superior, against the 65 per cent 

of those made between 1884 and 1900. 

Oonstituents.-The main constituents are given in 

horizontal rows on the left-hand page. This is the 

arrangement employed by Roth and by Osann, and 

it was adopted here rather than an arrangement in 

vertical columns, because it facilitates reference and 

for typographical reasons. With the chief constituents are included Ti02 , P20 5 , and MnO, since these are 

iu goneral the most important of the minor constituetts, and the two former are present iri all excellent 

and good analyses and in many that are rated fair. 

C02 and BaO have been transferred to the column 

headed "Inclusive," partly for spatial reasons, partly 

not to magnify their importance,. and partly because. 

most of the rocks that contain C02 are not fresh and 

have been transferred to Part III. 

In analyses in which the iron oxides are not sepa- . 

rately determined, the figures are given under Fe20 3 or 

FeO, according to the statement of the original analysis. 

When, however, there is no indication as to this point 

in· the original, the t~o oxides being connected by a 

bracket, I have assumed that they really represent 

Fe20 3, as this is the form in which they are weighed. 

This may not always correspond with the facts, but 

their nonseparation greatly lessens the value of the 

analysis, and this seemed the most reasonable assumption to make in order to calculate the norm, so that 

this course has been uniformly followed in the absence 

of information to the contrary. 

When they are so stated in the analysis, combined 

and hygroscopic water are both given, but no attempt 

has been made to discriminate between the various 

temperatures at which the hygroscopic water has been 

·determined. Usually this is 110°, but often 100° or 

105°, and occasionally 120° or 130, 0 • The difference in 

the result is so small and unimportant that it seemed 

to be not worth while to indicate the exact temperature. 

Nor is indication given as to whether the water has 

been determined directly or as loss on ignition. This 

is a defect in the collection which is regretted and 

which would have been corrected were time and opportunity at my disposal. It arose from the fact that 

a very considerable number of analyses had been collected before publication was decided on, and in these 

the discrimination had not been made. As a matter of 

uniformity, the same course was adopted in the analyses collected subsequently. It may also be remarked 

that most analyses as originally published give no 

'hint as to how the water was determined, so that even 

if special attention had been paid to this point, decision 

would have been impossible as to very many analyses. 

The molecular numbers of the main constituents are 

given below the figures showing percentages. Those 

given in the first edition have been gone over and corrected where necessary, and all those of other analyses 

have been calculated by me, even though they were 

given by other authors. In calculating these, the tables · 

given .in the puplication of the quantitative system 1 

have been used. In taking the figures from these 

tables, when the second decimal of the percentage was 

4, 5, or 6, and there was a gap of two units between the 

tabulated ratios above and below, the figure chosen 

was that midway. Thus, with 4.84, 4.85, or 4.86 per 

cent of CaO, the ratio given is 0.087.

FEATUR.ES OF THE TABLES. 31 

If the iron oxides have not been separated and are 

stated in the analysis as Fe20 8 only, the molecular 

number of the ferric oxide as stated is given, and the 

equivalent of this number reckoned as that of FeO is 

gi,-ren in parentheses and used in calculating the norm. 

If the alkalies are in excess of Al20 8-that is, if normative acn1ite i~ present-the appropriate n1olecular 

amOlmt of Fe2

0 8 is given m1der this head and the rest 

of the iron calculated as FeO. It may be noted that 

the n1olecular ntuuber of FeO equivalent to Fe20 8 is 

obtained by doubling that of the latter. 

The 1ninor constituents, except Ti0 2 , P20 5 , and MnO, 

are placed in the colunu1 headed 11 Inclusive" and their 

n1olecular numbers are on1itted. 

In checking the sumn1ations a number of errors in 

the original figures were detected. Each of these errors has been corrected by giving the proper summation above that given ·in the original paper, which 

appears below in parentheses. 

· S1Jecijic g1·avity.-The specific gravity of the rock is 

given if it could be ascertained fron1 the original paper. 

The te1nperature at which it was determined is generally Oinitted, as it is but rarely of value. 

Symbols.-The symbol which represents the magmatic position of each rock 1 has been given in Part I, 

with cert11in modifications introduced later 2 to indicate :i.ntel'lnediate and transitional positions. I have 

introduced a further refinement, the symbol ". In the 

original publication parentheses ()were used to indicate 

a transitional magma. This device is retained here. 

'rhe symbol 1 was used to indicate that the magma 

was intennediate, this term including both transitional 

magmns and those that fall between these and those 

that stand in a central position. 3 For indicating the 

distal position no provision was 1nade, though Iddings 4 

uses 1 uniformly for this ptu·pose. As this is a subdivision of the intenuediate position· represented by 1

, 

the sec-ondary symbol 11 , used for seconds or ~ches, 

seems nppropriate, and I haye used it consistently in 

this sense in several recent papers, though unfortunately without explanation. 

For rocks of persalane, dosalane, dofemane, and 

perfemane classes only the symbol of the preponderant sulic or fetn.ic portion is given, as the other is subordinate or negligible.5 In those of the salfemane class 

the sy1nbol for the salic portion is given first in full 

detail, and belo\y (in italics) that of the fernie portion, 

which .is about equal in weight to the other. If the 

position is centrnJ in all respects the symbol 0 is

added, lack of it implying that only the generaZ symbol 

for the subrang or subgrad is intended. 

Norm.-The norm is given for each analysis in 

Part I, which includes all those that have been classified according to the quantitative system. As has 

been stated, the norn1 of every analysis which is found 

in the first edition, and whioh is here found in ·Part I, 

has been recalculated by me, and carried out to 

the second place of de~imals, which is generally the· 

significant figure. A number of errors in norms 

haYe been thus detected, for in the old norms the 

stated a.n1ount of magnetite frequently included the 

ilmenite, and MnO was also not generally reckoned in 

with FeO. The correction of these errors has necessitated a few changes in classification position. 

The norms of all other analyses here included have 

also been calculated by me, no norm being accepted 

as published. Here, again, son1e errors have been 

detected, some of them very serious, and generally 

due to a misunderst.anding of the principles on which 

the calculation is based. 

The norms have been scrutinized in the work of 

copying the analyses in the n1anuscript and many have 

been collated with those given by Iddings;4 so it is 

believed that few errors have been made and that 

they can be accepted as here given, though it is too 

much to hope that they. are all free from error. 

In calculating the norm, molecular amounts down 

to 0.001 have been recognized, especially of P20 5 and 

MnO, a lower percentage than 0.10 of the former and 

0.07 of the latter having been neglected.. The molecular ampunt of MnO has ·been reckoned in with that 

of FeO and, when necessary (as when hematite is 

present), has been assumed to form magnetite and 

ilmenite. BaO and SrO have been reckoned in with 

CaO when they a1nount, molecularly, to 0.002 or more~ 

When the rock contains cancrinite C02 has been ·calculated as N a2C08 , and this is regarded as salic. 

Cl has been calculated as N aCl (halite) and 808 as 

N a2S04 (thenardite), in accordance with the modification of the quantitative syste1n proposed in 1912.6 

In accordance with a later modification based on . ' researches in the Geophysical Laboratory, and for 

other reasons/ the akermanite molecule, 4Ca0 3Si0 ' 27 has been replaced by the calciun1 orthosilicate molecule, 2CaO.Si02 •. The new equations used for the 

calculation will be found in the appendix. Changes 

in position due to this modification are very few and 

of slight importance. Great care has been exercised 

in distributing FeO and MgO in the same proportions 

between diopside, hypersthene, and olivine, a slide 

rule proving very useful for this.

In stating the norm the salic and fernie molecules 

are kept separate, and are denoted by the symbols 

adopted for them. A list of all symbols used is given 

in the table of abbreviations on page 46. 

Locality.-The names of localities are those. given 

by the author, though lack of space necessitated the 

omission of some details. such as distances and quarry 

names. With some exceptions, such as the use of the 

name commonly accepted in English, the names of 

countries and localities are those which were in use 

prior to the present war. The name of the country 

is omitted if the State, province, or district is given 

and is well known, though it is inserted if the locality 

is small or little known, and if the province or other 

geographic division is not furnished by the original 

paper. The endeavor has, however, been n1ade to 

look up doubtful localities, Stieler's Atlas (1906) being 

used, so as to determine the province or district. 

The orthography of the geographic names conforms with the decisions of the United States Geographic Board so far as they extend. When these 

were not available, in case of doubt, Lippincott's 

Gazeteer (edited by Heilprin, 1906) was the accepted 

authority. I must disclaim responsibility for the 

omission of the apostrophe in such names as Pikes 

Peak, Lands End, and St .. Davids Head, which is in 

accordanc-e with the ruling of the United States Geographic Board. I may add that I thoroughlydisapprove of the omission as grammatically incorrect. 

With the exception of a, c;, e, e, :ii, o, and ii, diacritical 

marks are omitted from letters both in locality names 

and in the references. 

Analyst.-The name of the analyst precedes that 

of the author of the paper, because this is a collection 

of analyses and because the analyst is a useful factor 

in rating analyses. When known, the initials of the 

Christian names are inserted, but, as some were not 

given by the author and were unknown to me they 

are perforce omitted. If the analyst is· quite disregarded by the author I have had to rest content with 

the phrase ''not stated." 

Reference.-The aim has been, in the column headed 

"Reference," to indicate the author by whom and 

the place where the analysis was first published. Subsequent publication, whether by the same author or 

by others, has been as a rule disregarded. Many 

analyses, however, made for authors who are connected with Government surveys, notably the United 

States Geological Survey, have been first published 

in papers appearing in unofficial journals or pro-

. ceedings of societies, and only subsequently in 

official reports. For such analy.ses there is given in 

the column headed ''Reference'' the place of the first 

(unofficial) publieation, and under ''Remarks'·' is 

noted the place of the first official publication. This 

seems just to the Survey, for the analyses were made 

by official chemists. 

• 

In general, such publications as "Report of w9rk 

done," "Summary of progress," even though official, 

in which the analysis appears without a description 

of the rock, are neglected unless this is the only reference available. In the case of analyses made by 

the chemists of the United States Geological Sm·vey 

and published in unofficial jom·nals but not in official publications prior to 1914, only the place of 

first publication is given, not Bulletins 148, 168, 

228, 419, 591 of that Survey, in which they may 

appear. Reference to one of these five bulletins indicates that the analysis has been found only in that 

bulletin or elsewhere as a citation fr01n it. In such 

cases the ''author" cited is the petrographer who 

furnished the description for the bulletin. 

The page number 1 given in the reference is that on 

which the analysis occurs, not that on which the 

paper commences. The date given is the year of 

publication, not the year for which the report is 

issued, this being placed in parentl?-eses (). In dissertations the university name is given, not that of 

the place of publication. A number of analyses were 

found in the Refer ate of the N eues J ahrbuch, which 

have been published in papers inaccessible to me, and 

which would, therefore, otherwise have escaped incorporation in the collection. The pages on which these 

analyses appear are not mentioned in the Referate of 

the J ahrbuch, so I give only the name of the author 

and a reference to the N eues J ahrbuch. 

I have, unfortunately, been obliged to omit many 

analyses that have appeared in journals published in 

languages with which I am unacquainted, notably· 

Russian, Bohemian, Magyru·, and Japanese, for the 

impossibility of understanding the context left me in 

ignorance as to the occurrence or character of the rock. 

I have to thank Dr. H. Backlund for his help in 

obtaining a number of analyses of Russian and 

Siberian rocks through his kindness in translating 

the Russian text. I must also aclmowledge the 

assistance of Dr. E. W. Posnjak, of the Geophysical 

Laboratory, in a similar way. To Dr. S. Kozu I an1 

indebted for a series of analyses of Japanese rocks 

published about 1884. 

In the interest of the general scientific world, 

whether geological, zoological, botanical, physical, 

chemical, or other,· I desire to register a protest 

against the publication of scientific 1natter in such 

languages, whether by. official enforcement or not, 

even though it be ameliorated by the addition of an 

abstract in one of the languages-English, French, 

German, or Italian-With which every scientific 

man is supposed to be acquainted. National p1~ide 

or other feelings should not impose such extra and 

unnecessary burdens on the man of sci~nce. For 

my own part I an1 forced to regard analyses or other

COMMENTS ON SYSTEMATIC NAMES. ~33 

scientific data that are published only in such languages, which are unknown to the great body of 

scientists, as so nearly unavailable and lost to science 

that they n1ay be considered as unpublished. 

The nmnes of organizations and journals are given 

in abbre-viated forms, which have been nutde as concise as see.med consistent with clearness, and it has 

been an aiin to establish son1e standard for1ns of 

abbreviation for the use of petrographers. In this 

I have been aided by, and have partially followed, 

the lists in Dana's Systmn of Mineralogy (1892) and 

the Geologisches Centralblatt (I, 1901), though I 

have n1ocli:fied their abbreviations in many particulars, chiefly in the direction of still further condensation. A list of the abbreviations generally adopted 

will be found on pages 45-46. 1 

Boclc n((/me.-The nmne of the rock which has been 

designated by the author of a paper cited is given 

under the heading ''Rock name." A few minor 

changes have been 1nade in these names, notably the 

replacement of eleolite or nepheline by nephelite, and 

the occasional shortening of son1e nan1es c01nposecl of 

those of several 1ninerals, as pyeoxene-aridesite for 

hypersthene-augite-andesite. A few different names 

that have been given to the same rock by others 

appear either under this heading or in the last column. 

Rmnarlcs.-The colmnn headed "Re1narks" contains infor1nation for which there is no place elsewhere in the tables· or re1nar~s on certain features 

of the analysis of the rock. Here, also, attention 

1nay be cnlied to features of the analysis which 

1nay be regarded with suspicion. This information 

is of necessity stated very concisely, or it may be> 

omitted, since any discussion is out of the question 

in the s1nall space available. An ·analysis that has appeared in the first collection is indicated here by the 

phrase "In ,V. T.," with page nu1nber, so that its 

eo.rlier and present positions 1nay be readily compared. 

I:f the elate of the analysis is prior to 1901 and the 

analysis was not included in the fil'st collection, the 

phrase "Not in vV. T." is used. 

COMMENTS ON NORMATIVE NAMES. 

Since the publication of the :first edition a considerable nun1ber of new nan1es have been given to various 

su brangs and other divisions of the quantitative systmn, and a few more have been given and changes 

made in the present work. There has been some 

duplication of names, the systematic position of some 

newly named divisions has been incorrectly calculated, 

the speci1nens of rock on which other names were 

based lutve not been fresh, or the analyses have been 

inferior. 

1 Owing to tho considomblo length of time over which tho writing or the manuscript o..'Ctondod tho uso or tho abbreviations is, unfortunately, not perfectly uniform. 

42423°-17--3 

A short list of new names was published in 1912, 2 

but without extended comment. In the 'original publication of. the quantitative system only a few suggestions were made as to the formation of new systematic names. It may therefore be appropriate to 

discuss here briefly the general principles of nomenclature and the laws of priority applicable to the 

acceptance .or rejection of new names. Comments 

will also be made on some systematic names, including some given in th<;) original publication and some 

proposed subsequently. Tllis matter has been discussed with the other authors of the quantitative system, and the views here expressed in general meet 

with their approval. It may be confessed that the 

subject is in places somewhat complex and that some 

inconsistencies may possibly appear in the choice of 

names in the present compilation. 

The rules that were :finally suggested for adoption 

and that are followed in the present work are stated 

below: 

1. N an1es based on rocks ";hich are obviously or 

have been shown to be nonigneous or metamorphic, 

or are certainly or possibly of meteoric origin, have 

no standing. Thi$ rule excludes such names ·as 

kodurose and boiranose, sitkose, and many names proposed by Summers, based on australites, moldavites, 

and other possibly or pi·obably meteoric but not certainly igneous bodies. The subrang names applied 

to meteorites by Farrington,S though appropriate for 

them, should not be appli eel to con~esponding te?"Testrial 

igneous rocks. 

2. Names should not be applied to divisions regarded 

as negligible in the original publication of the quantitative system. This applies especially to subrangs 

of percalcic rangs·, such as caledonose and ouenose. 

3. If the assigned position of the rock on which the 

divisional name is based is incorrect because of faulty 

calculation of the norm or because of other errors, 

the name is to be regarded as doubtful. This has been 

found to be the most frequent cause of uncertainty in 

determilling questions of nomenclature, and a certain . 

amount of latitude must be left to the systematist in 

accepting or rejecting a name so assigned. If the 

assigned position is not already preempted, and no 

very serious error of calculation has been made, the 

name may be allowed to stand as originally applied. 

Such a case is that of palisadose or of kakoulimose. 

If, on the other hand, no very serious error in calculation has been made, and the correct position is not 

named, the new designation may be transferred to the 

division to which it properly applies, as was the na1ne 

pienarose. If, however, a very serious error ~as .been

made in the assignment, as by inadvertently stating · 

that a rock is· dopotassic when it is dosodic; and when 

its proper position is already named, the new name 

should be dropped. Craigmontose is a case in point. 

The. names to which rule 3 applies are the most numerous, those which have caused most perplexity, 

and which have given rise to most inconsistencies. 

The attempt has been made in this publication to 

treat them with justice and with due regard to the 

stability of the terminology o~ the system, and the 

prevention of confusion, in so far as possible, to future 

systematic terminologists. 

4. A new name should not be based on the analysis 

of a rock which is obviously not fresh, however good 

the analysis may be. l\1ainare, lermondose, and 

washingtonose are cases in point. 

5. A name based on an analysis which is clearly 

seriously inferior, either in accuracy or completeness, 

. as to the major constituents, is not entitled to recognition. Taurose and vulcanose are examples. 

6. The application of names whose roots are taken 

from small localities to the larger divisions, such as 

class or subclass, is to be deprecated, as well as of 

names whose roots are likely to be misinterpreted. 

Examples of these are gorduniare, rhodare, and 

piedmontase. 

7. Names should not be based on rocks that occupy a 

transitional position, that is, very close to the border 

of another division. This rule applies to many names 

already published within the original tabulation and 

subsequently, as study of the syn1bols given in the 

following pages will abundantly show. They have 

been allowed to stand, but it is to be hoped that in 

the future names thus based will not be bestowed. 

On the other hand, examination of the magmatic 

symbols in Part I will show the extreme rarity of 

rocks that are central as regards all the divisions. In 

practice, therefore, a name may be based on a rock 

whose symbol includes distal (cf. p. 31) signs ("), 

but not transitional, indicated by parentheses ( ) . 

8. The generally accepted laws of priority, such as 

are enunciated by Dana in his System of Mineralogy, 

are supposed to hold good as to duplicated names. 

9. Other things being equal, it is preferable to b.ase 

the name of a systematic division on the nan1e of a 

rock according to that given it in the qualitative sys-

. tern, if such a name be available. 

In Part I of the present edition, and in the tables 

given in Appendix 2, will be found, in their appropriate systematic positions, all the names which have 

been proposed up to the time of its compilation, and 

which are deemed worthy of acceptance under the 

rules stated. A number of these names will now be 

'discussed. AU known names have been collected and 

collated, and the questions of priority and of the acceptance or rejection of names have been discussed, 

so it is hoped that the present work may serve the 

future tern1inologist as a definitive point of departure. 

In the following pages of commentary, which embraces only those names which seen1 to require con1-

n1ent, names that have been rejected are printed in

analysis of a type specimen falls in II. 8. 2. 4. 

II. 8. 2. 2. VESUVOSE (C.' I. P. W., 1902). This 

nmne should have been applied to II. 7. 2. 2 BRACOIANOSE, in which n1ost of the analyses of Vesuvian lavas 

fall. 

II. 8. 2. 4. MELFOSJ~. New name, represented by 

an unpublished analysis of typical hauynophyre of 

Mel:f:i, Monte Vulture. 

III. 3. ATLANTARE (C. I. P. W., 1902). Nan1e very 

badly chosen and objectionable. Represented only by 

duplicate analyses of one small specimen. Hibernare 

would have been better, as Ireland is not represented. 

III. 5. 1. 4. PrENAROSE (H. A. Brouwer, 1910). 

Name incorrectly assigned to III. 6. 1. ;4 through 

erroneous calculation. 

III. 5. 5. 4-5. Ouenose (A. Lacroix, 1911). Name 

rejected under rule 2, subrang name not needed. 

III. 6. 1. 2. Washingtonose (F. L. Ransome, 1908). 

Name rejected, as the rock is not fresh.

III. 6. 1. 4. Prr..ANDOSE (Washington, 1914). New 

name to replace Brouwers's pienarose, incorrectly 

applied, which really falls in III. 5. 1. 4. 3 

III. 6. 2. 2. KAJANOSE (H. A. Brouwer, 1909). 

Name omitted from list of C. I. P. W., 1902. 

III. 6. 4. Amargase and III. 6. 4. 4-5. Amargose. 

(F. L. Ransome, 1910.) Names rejected, as the rock 

analyzed is not fresh (cf. p. 921). 

III. 6. 4. 4-5. PAPENOOSE (Lacroix, 1910). The 

rock analyzed falls in IV. 2. 2. 2. 2 (MONTREALOSE, 

Adams) but is very close to the border of Class III 

(cf. p. 721), so that papenoose is accepted in place of 

· amargose (F. L. Ransome, 1910), based on a weathered 

rock. 

III. 8. 1. 5. Tavose.(V. I-Iackman, 1905). Rejected 

as based on a very bad analysis (cf. p. 1133). 

In the dofemane and perfemane classes, in accordance with a recent publication,·! the rangs are now 

based on the ratio :Mg0+:fe0+Na20": CaO, instead 

of on the ratio MgO + FeO + CaO" :N a20", as originally 

used. 

In the present work, therefore, in these classes the 

rang name is consistently that of the earlier section of 

rang name (with the "i" omitted), which had the same 

.name root. 

IV. 1. 2. QuEBECIARE (J. A. Dresser, 1909). Has 

priority over Hawaiiare (R. A. Daly, 1.911). 

IV. 1. ·2. 2. · 2. PALISADOSE (J. V. Lewis, '1907). 

Lewis's olivine diabase falls transitionally in IV. 1. 2. 

1. 2 (HrLOSE, R. A. Daly, 1911),· but the name is 

accepted as having priority over this and hudsonose 

(G. S. Rogers, 1911) and thiose (A. Lacroi.-x:, 1911), 

the last falling in IV. 1. 2. 2. 2. 

IV. 2. 2. PAULIARE, IV. 2. 2. 3. PAULASE, and IV. 

2. 2. 3. 2.' PAur..osE (C. I. P. W., 1902). In original 

publications incorrectly spelled paoliare, paolase, and 

paolose (p. 583). 

IV. 2. 3. 3. 2. NAKETOSE (A. Lacroix, 1911). 

Analysis incorrectly placed by Lacroix. In uvaldose, 

IV. 2. 3. 2. 2. Tulamose (C. Camsell, 1913) is rejected, 

as serious errors were made in ·the calculation~ the rock 

falling in IV. 2. 2. 2. 2, and naketose has priority.

incompletely given as IV. 4. 1. 1, the subrang symbol 

having been omitted.

worth, which has priority over the name harzburgite of 

Rosen busch. 

V. 1. 4. I-IELVETIARE (I-I. S. Washington, 1916). In 

accord with rule 6 this is adopted in place of Grubenmann's gorduniare (1908), which bases a subclass 

name on .that of a small valley. It is also appropriate, 

as most of the known analyses falling here are of rocks 

in or near Switzerland, a country hitherto unrepresented· in the nomenclature. Grubenmann's name 

root is preserved in rang V. 1. 4. 1. GoRDUNASE, and 

subrang V. 1. 4. 1. 1. GORDUNOSE. The form.er name 

is objectionable as liable to confusion with gordo'nase 

II. 3. 5. 0, now rejected (cf. p. 35) .. 

V. 1. 4. 1. 2. KAKOULIMOSE. The analysis falls transitionally in GUINEOSE V. 1. 5. 1. 2 (cf. p. 741). 

v. 3. RHODARE (C. H. vVarren, 1908). This name 

is accepted, though it is objectionable because it is 

based on the narne of a State and because the name 

suggests the Island of Rhodes rather than the State of 

Rhode Island. Warren's name root is adopted in V .. 

3. 5. 1. RHODASE and V. 3. 5. 1. 3. RHODOSE. 

V. II. 2. Mainare, V. II. 2. 3. Mainiare, and V. II. 

2. 3. 1. 2. Lermondose (E. S. Bastin, 1908). These 

names are rejected as based on an analysis of a 

pyrrhotite peridotite which was not fresh and in which 

the two iron oxides had not been determined (cf. p. 925). 

V. II. 5. 3. 3 . . Lovingstonose (Watson and Taber, 

1913). The name is rejected as being only provisionally proposed and based on an analysis of a not 

fresh rock, which falls in a transi~ional position. 1 

THE MAKING OF THE COLLECTION. 

It may be of interest to give a few details regarding 

the actual making of the collection, as it has gro~ to 

proportions so large that such an undertaking will not 

probably be attempted again in its entirety. For this 

reason, in forming the present collection, the aim hae 

b~en to make it as complete as possible, within the 

time limits set-that is, from 1884 to 1913, inclusive. 

For this purpose the excellent library of the United 

States Geological Survey was thoroughly examined. 

This library contains about 100,000 volumes and over 

100,000 pamphlets, and has a growth of about2,600 volumes a year, all relating to geology and allied sciences. 

"It has ahnost complete sets of the publications of 

national and State geological surveys, both of America and foreign countries, and sets of all serials devoted 

to geology. It contains practically all the literature 

of geology, paleontology, and mineralogy." 2 The only 

geological library that possibly surpasses it is that of 

the Geological Society of London. 

Every serial,3 whether published by a survey, society', 

or other organization, which might conceivably con1 Cf. Watson, T. L., and Taber, Stephen, Virginia Geol. Survey Bull. III-A, p. 

127, 1913.

Washington, 1914. 

s The Ermuterungen zur geologischen Karte Preussen has not been examined 

since 1900 as the subsequent volumes all arrived together just as the work was being 

finished. 

tain petrographic n1aterial was examined volume by 

volume. This exan1ination embraced publications for 

the years from 18S3 in to 1914 or 1915, though the end 

of 1913 was decided on as the final limit. The last 

number of each one from which analyses were collected 

will be found in the list of publications examined. 

Such nonpetrographical publications as the Paleontologica Indica and the reports of the geological surveys of such States as Ohio, Iowa, and Alaba1na, which 

would presu1nably contain no petrographic descriptions of igneous rocks, were neglected. Purely technical journals, like the Engineering and Mining Journal, Mining World, and Berg- und hiitten1annische 

Zeitung, were only cursorily examined, as they would 

presumably contain little material of value for the 

purpose in view. The large collection of 1nore recent 

separates, dissertations, and other pamphlets was also 

gone ov.er, as well as my own collection of separates. 

· In addition, many books on the geology of various 

regions, books of travel, and other volumes were 

searched for analyses. 

The analyses found were copied on cards directly 

from the publications, with the requisite data as to 

reference and other necessary features. The make-up 

of these cards has varied fron1 time to time, and the 

form finally adopted is shown in actual size in figure 1, 

giving the obverse and reverse of one as actually 

filled out and the calculation of the norm. 

These cards were first arranged geographically, by 

countries and localities and percentage of silica. In 

this way duplication and different places of publication of the same analysis were detected. They 

were then gone over carefully to determine the 

rating and general quality, after which the norms 

of those whiQh were deemed to be fresh and of superior quality were calculated and the symbols noted. 

All the cards of . the superior analyses were then 

arranged according to the quantitative .s~yst.e.m, after 

which they were copied on large sheets which bore the 

column headings and ruling shown in the tables. A 

careful reexamination was made of the analyses 

rejected from Part I, to distribute them among Parts 

II, III, and IV, during which a few were restored to 

Part I. On the other hand, during the writing of the 

manuscript of Part I, reconsideration of a number of 

analyses led to their relegation to other parts·. 

Fortunately nearly all the cards used for the preparation of the first edition had been preserved, and these 

were carefully collated with the analyses published in 

the first edition and the missing ones copied off, so 

that all those there given are reproduced here. Appropriate changes were made in the references, 

especially for the analyses made in the Survey laboratory and published in Bulletins 148, 168, 228, and 

419. Many of these have since been republished, in 

connection with the papers for which they were made, 

in other later Survey publications. Through the 

kind1iess of F. '\'V. Clarke, chief chemist, I had access

to tho records of the laboratory, anQ, with the kind 

pe:nnission of the geologists of the Survey for whon1 

they were made, I have incorporated in this collection 

nutny analyses which are not yet published or which 

are appearing frmn tin1e to tin1e. The r~cm~ds were 

ex111nined up to January 1, 1915. 

It 1nay be of interest to give some figures regarding 

the thne 11ctively employed in 1naking this collection, 

including that devoted to the search through the literl1turo, copying off the 11nalysis, calculating the norn1,

periodicals available in the libraries visited. In the 

list arranged by authors there are some papers in 

serial publications that contain so many analyses or 

are otherwise so important that they have been 

deemed worthy of separate citation by authors' names. 

Neither list is quite con1plete, for some serials and 

books have been omitted because they were of minor 

i1nportance or for other reasons; but the two lists

expected to -contain rock analyses. 

The serials are arranged alphabetically by countries. 

Under each country the publications of the official 

surveys are given first and are followed by journals 

and publications of societies in general alphabetical 

order. In the second column is given the last ilumber that has been examined, and in the third the 

abbreviation that has been adopted and generally used 

in the tables. The second · list is arranged alphabetically by authors and the name of each book or

ADDENDA TO NORMATIVE NAMES (page 35). · 

II.7.1.5. ANTANGAINOSE. Name proposed by A. Lacroix (personal communication); represented by a rock from Madagascar 

(p. 581). 

II.7.2.3. BAWEANOSE. Name proposed by J. P. Iddings (personal communication); represented by a rock from Bawean !Aland 

(p. 581). 

III.9.1.1. MADUPOSE. Name originally applied to III.9.1.2. 

The single analysis is transitional as to subrang (p. 701). Transfen·ed to 'this position.(perpotassic), as it actually falls here and 

because it thus harmonizes better with orendose (III.5.l.l) and 

wyomingose (III.6.1.1). Also, III.9.1.2 is not represented by an 

analysis. 

IV.2.3.1. Texase. Rejected·and replaced by UVALDOSE, to conform with a modification of rules for nomenclature suggested by 

C.I.P.W. (Jour. Geology, vol. 20, p. 553, 1912).

APPENDIX 1. 

THE QUANTITATIVE CLASSIFICATION OF IGNEOUS ROCKS. 

INTRODUCTION. 

As the original publications 1 on the quantitative 

·systmn of classification and on some modifications of 

it, as well as some more recent descriptions, 2 may not 

be readily available to 1nany readers, a concise account 

of it is given here. More complete details are given in 

those publications ns well as in published. discussions 

of the classification. 3 

GENERAL PRINCIPLES. 

The system is a quantitative chemico-mineralogical 

one: The chemical composition of igneous rocks is 

regarded as more fundamental than their mineral 

cmnposition or their texture, so that a~i igneous rocks, 

irrespective of the commonness or rarity of their 

occurrence, are classified pri1narily according to their 

chemical composition, with the object of grouping 

.together rocks of like chemical composition, with_\n 

lin1its. · Tllis phase alone of the classification concerns 

us here; mineral .composition and texture, wlllch are 

regarded as of subordinate ·importance, will not here 

be considered. · 

The chemical character of a rock is expressed in 

terms of the molecules of certain minerals that are 

capable of crystallizing 'on the solidification of a 

magma of a given chemical composition. The expression of the relations of these molecules is quantitative. For this purpose a selection is made of the 

n1olecules of the rock-makiJ:ig minerals wlllch agree so 

far as ·is possible (and in fact do so to a very large 

extent) with the actual rock-making minerals. These

mineral qi.olecules are known as standard, the minerals 

that actually make up the rock being called modal. 

For a proper comprehension of the system of classification it i& of the utmost ilnportance to be-ar the distinction in mind, and to grasp the fact, that the standard 

mineral molecules used are molecules and not minerals. 

This point was not sufficiently· emphasized in the original publication, and the neglect to state it explicitly 

has led to sonie misunderstanding and consequently 

some unjustifiedly adverse criticisms of the classifi~ 

cation. 

The modal aluminous pjroxenes, amplllboles, micas, 

garnets, and melilite (called collectively alferric 

minerals), being very complex and variable in composition, are not included in the standard 1ninerals and 

are not regarded in tills phase of the classification, 

for reasons of practicality given in the original papers. 

The con1position of the roc~ expressed in terms of 

the standard mineral molecules is called th(;) norm, 

and the actual mineral composition, expressed quantitatively, is called the mode. The nor1n may or may 

not correspond with the mode, but as nearly all the 

standard molecules actually express commonly occurring rock · n1inerals (mixtures of isomorphous 

inolecules, ~s in the feldspars, being taken into account), the norm and the mode correspond very 

closely· with each other in very many, if not the 

n1ajority, of holocrystalline rocks .. 

CONSTRUCTION OF THE SYSTEM. 

'rn the construction of the system as outlined above, 

two considerations, involved in the characters of 

rocks, are of paramoimt importance. These are the 

number of variables that must be dealt with and the 

unbroken continuity. of gradation between all the 

factors of the same category involved in the problem. 

The constituents that may- enter. into the chemical 

composition or into the norm of a rock are numerous, 

. the number of chemical constituents to be considered 

in a superior analysis being scarcely ever less than 10 

and possibly reaclllng 20, and the number of standard mineral molecules about 30. The fact is now 

generally recognized that there are no sharp or "natural" divisions between igneous rocks, as these grade 

into one another in every respect, whether of chemical 

composition, mineral composition,· or texture, the last 

including either crystallinity, granularity;· or fabric. 

It has been found that the best if n<;>t the only 

practicable way . of dealing systematically with the 

1151 
1152 CHEMICAL ANALYSES OF IGNEOUS ROCKS. 

numerous variables of the norm is to treat them 

dichotomously~that is, to divide them into a series 

of pairs of contrasted variables, each successive pair 

expre$sing characters of successively. l~ss generality 

or magnitude and of correspondingly greater particularity and definiteness. · 

The use of percentages to express the relations of the 

two variables is preferable to the use of ratios, which 

were used in the original publication, because the use o.f 

ratios involves the consideration of hyperbolic. curves, 

thus tending to conceal the true relations.1 'Statement in percentages is commonly .used for the graphs 

of physical chemistry. · 

The continuous gradation in the character of rocks 

and the absence of natural divisions n.ecessitate 

arbitrary divisions, in making which, furthermore, the 

fact must be considered that in any pair either one of 

the variables may be present to the exclusion of the 

other. fu the present system of classification this 

arbitrary division is accomplished by selecting five 

center points, which -seem to be those that are ·most 

obvious and practical in .showing the relations of two 

variables in any pair. These center points are indicated below, the relations· being expressed both in 

percentages and ratios: It should be noted that 

these and all subsequent percentages here given express 

only the sum of the amounts of the two v3.riables 

contrasted. They are not percentages of tfie ri.orm 

(except in classes) o:r of the rock. 

Two center points are used where one variable, A orB, is present 

to the exclusion of the other. A=lOO, B=O; or A=O, D=lOO. 

A :B=1 :0 or 0:1. 

One center point is used where ~oth variables are. present in 

equal amount. A=50, B=50. A: B=1: 1. 

Two intermediate center points are used where .the amount of 

one. variable is three times that of the other. A=75, B=25; or 

:A=25, B=75. A :B=3 :1 or 1':3. 

The limits of the divisions of a series marked by 

these center points are where the percentages are as 

follows: A=87.5,· B=12.5; .A=62.5, B=37.5; A= 

37.5, B=62.5; A=37.5, B=62.5;· A=12.5, B=87.5. 

The corresp<;mding ratios are A: B = 7: 1, 5:3, 3:5, 1:7. 

If one of a p~ir of variables is present in amount equal 

to or greater than 12.5 per cent of the two it is said to 

be notable, but if its amount is less than this it is said 

to be negligible. 

These general divisions are nun1bered and defined. 

as follows, the prefix being annexed that indicates the 

relation in the nomenclature. 

1. A is extreme over B, B being negligible. Prefix per, applied 

to A. 

2. A is dominant over B, both being notable. Prefix do (dom), · 

applied to A.

OUTLmE OF THE SYSTEM. 

DIVISIONS. 

The divisions made in accordance with the prineiples sta-ted and the terminations that distinguish the 

divisions are as follows: 

Class (-ane). Subclass (-one). 

Order (-are). Su'!:>order (-ore). 

Rang (-ase). Subrr..ng (-ose). 

Grad (-ate). Subgrad (-ote). 

"Sections" of any of these are indicated by the insertion of "i" between the root and the regular termination. , 

Of these divisions, class, subclass, order, suborder, 

rang, and subrang are of chief interest ·here. The 

classification presented in this collection has not. been 

. carried as far as grad and subgrad, so that these will 

be treated very briefly. 

For the pl,ITpose of carrying out this classifiqation 

the standard mineral molecules, 2 in terms of which the 

norm is calculated-the .normative mole~mles, are 

first divided into two groups. The first group of 

molecules called salic, characterized in general by the 

presence of silica and alumina, includes the molecules 

of quartz, corundum, zircon, orthoClase, albite, anorthite, leucite, nephelite, and a few others of minor 

importance. The second, called fernie,· characterized 

by being nonaluminous and in general by the presence 

of magnesia and iron o:Xides, includes the molecules 

of acmite, diopside, hypersthene, wollastonite, olivine, 

calcium orthosilicate, magnetite, ilmenite, hematite, 

.apatite, and a few others of minor importance. In the 

· course of the classification each· of these two groups 

will be further subdivided into parts and these into 

still smaller divisions. · · 

A diagrammatic scheme of the classification is shown 

in figure 2. This is necessarily incomplete and expresses in detail only the chief successions of divisions, 

which, however, include most of the igneous rocks. 

sA list of the standard mineral molecules will be found on p. 1163.

CLASSES. 

The. classes are based on the relative amounts of the 

collective salle and fernie molecules in· the norm. 

There are five classes: 

Class I "(persalic). The salic molecul~s are extreme over the 

fernie. Center point: sal:=lOO, fem=O; sal:fern=1:0. Limits: 

sal:<I00>87.5; fem:<0>12.5; sal; fem=1:0. 

Class II (dosalic). The salic molecules are dominant over the 

fernie. Center point: sal=75, fem=25; sal:fem=3:1. Limits: 

sal-:<87.5>62.5, fem:;:12.5<37.5; sal:fem-:<7:1>5:3. 

Class III (salfemic). The salic and fernie molecules are equal 

or nearly equal in amount. Center point: sal=50, fem=50; 

sal:fem=1:1. Limits: sal:<62.5:;:37.5; fern :;:37.5:<62.5; sal:fem 

:<5:3:;:3:5. . 

Class IV (dofemic). The fernie molecules are dominant over the 

salic. Center point: sal=25, fem::=75; sal:fem=1: 3. Limits: sal 

<37.5:;:12.5, fem>62.5:<87.5; sal:fem<3:5:;:1:7. 

·Class V (perfemic). The fernie molecules are extreme. over the 

salic. Center point: sal=O, fem=100; sal:fem=O: 1. Limits: sal 

<12. 5:;:0, fern>87.5"<:100 . 

. · In subdividing. the classes as ·far down as and including subrang, only the ·salle molecules are considered 

in Classes I, II, and III, and only the fernie in Class~ 

IV ·and V. In Class III the amount of the fernie 

mole~ules :p:tay equal or even exceed (up to the limit) 

that of the salic molecules; but here the fernie group 

1s treated .as subordinate for reasons give~ in the 

original publication and also by Iddings.1 

SUBCLASSES • 

The subclasses are based on the relative amounts of 

certain parts into which the salic and fernie groups are 

divided, as follows:. 

Sal {Part 1. Quartz (Q), feldspars (F), feldspathoids (L). 

Part 2.· Corundum (C), zircon (Z). 

l

Part 1. Pyroxenes (P); olivines and calcium orthosilicate 

F · · (0); magnetite, hematite, ilmenite, rutile, titanite, 

em perofskite (M). 

Part 2. ,Apatite, fluorite, .pyrite, etc. (A). . . · 

In Classes I, II, and· III the division is fivefold and 

is made on the basis of the relations of the two variables (Q +F +L) and (C +Z). In Classes IV and V 

it is likewise fivefold but is made on the basis of the 

relations of the two variables (P +0 +M) and (A). 

rrhe center points and limits are identical in position 

with those of the classes. In Subclasses II, III, IV, 

and V of Classes I, II, and III _the relative' amounts of corundum (C) and zircon (Z) may be recognized 

by sections formed by contrasting these two variables 

in the same way, the division being threefold in Subclass II and fivefold in the others. 

As most ign~ous rocks belong to Subclass I of any 

class, the· succeeding. description of the classification 

· will pertain only to Subclass I of each Class:

1154 CHEMICAL ANALYSES· OF IGNEOUS ROCKS~ 

ORDERS.r 

The orders are based on the relative amounts of the 

subparts of mineral molecules th_at constitute part 1 

of the salic and part 1 of the fernie group .. 

In Classes I, II, and III the division is based on the 

molecules .of part 1 of the salic group. To carry this 

div.ision out rigidly Q should l;>e contrasted first ·with 

(F + L), expressing thus the degree of excess of silica. 

Bu.t as was pointed ·out by Zirkel 1 quartz ·and the 

lenads 2 (leucito and nephelite) are incomp~tiblethat is, they never coexist in igneous rocks, so far as 

known, and as the feldspars may· occur with ·either, 

thes.e three variables are treated serially-that is, as 

a combination of two pairs of variables,. quartz mole-. 

cules being contrasted with feldspar molecules, and 

these in turn, without a break, with lenad · (feldspathoid) molecules. The division is doubly fivefold 

and these orders are defined as follows, tho positions 

of the center points· and limits being the same as with 

classes. · Orders of Classes I, If,· and III. 

Order 1 (perquaric). Quartz extreme over feldspars. 

Order 2 (feldoquaric). Quartz dominant over feldspars. 

Order 3 ( quarfelic). Q.uartz and feldspars equal. 

Order 4 (quardofelic). Feldspars dominant over quartz. 

Order 5 (perfelic). Feldspars extreme over quartz or lenads. 

Order 6 (lendofelic). Feld&pars dominant over lenads. 

Order7 (lenfelic). Feldspars and lenads equal. 

Order 8 (feldolenic). Lenads dominant over feldspars. 

Order 9. (perlenic). Lenads extreme over feldspars: 

In Classes IV and V the· division is based on tho 

molecules of part 1 of the fernie group. These ·are 

molecules. of minerais that are not incompatible in 

igneous rocks, so that the division is not serial, as 

before, but fivefold and in two steps. For this purpose the silicate molecules of pyroxene~ (P) and olivines (0) are first contrasted \vith tho nonsilicates (M) . 

This procedure is carrie.d out as in the prec~cling divisions, the positions of the center points and limits 

being the same. 

Orders of Classes .IV and V. 

Order 1 (perpolic). P+O extreme over M. 

Order 2·(dopolic). P+O dominant over M. 

Order 3 (polmitic). P+O and M equal. 

Order 4 (domitic) .. M dominant over P+O. 

Order 5 (permitic). 1~ extreme over P+O. . 

The relative amounts of the metasili~ates (P) and 

the orthosilicates (0) are expressed analogously in sections of an order. ·In' orders 1, 2, and 3 the division is 

fivefold and analogous to. the preceding cases. 

Section 1 (perpyric). P extreme over 0. 

Section 2 (dopyric). P dominant over 0. 

Seetion 3 (pyrolic). P and 0 equab 

Section 4 (domolic). 0 dominant over P. 

Section 5 (perolic). 0 extreme over P.

"Hiorvo~ ist bis jotzt eino Ausn::thmo nioht gofundon, so dass d!es zur Zeit als ein 

wirklicbes Gesetz gelton muss, allord!ngs fast das einzige diescr Art." 

2 Lcnad is a term used to replace feldspathoid. 

In order 4., as .the factor P+O is subordinate, 

though notablej;: :the division is threefold,· as follows: 

Section 1-2 (prepyri_q:). · P preponderant over 0. 

Section~ (pyrolic). 1.P and 0 equal. ·· 

Section 4-5 (preolic). 0 preponderant over P. 

In order 5, as the factor P +0 is negligible, there is 

no subdivision. 

SUB,ORDERS. 

The classification .into suborders involves a consideration of the different acidic radicals that may be 

present in the molecules so far considered and is based 

on their relative amounts. In Classes I, II, and III 

suborders are called for only in orders 7, 8, and 9, where 

they are based .on the relative amounts of the silicate 

·molecules .(leucite and nephelite) and the chloride and 

sulphate molecules. (halite and thenardite) in the norm, 

the relations between the last two being brought out 

in sections of these suborders. In orders 3, 4, and 5 

of Classes IV and V the suborders are based on the 

relative amounts of the hemic molecules containing 

Fe20 3 (magnetite and: hematite) and the tilic molecules 

containing Ti02 (ilmenite, titanite; perofskite, rutile). 

As illustrating the extended possibility of classification in this system, it may be pointed out that the last 

four variables may be classified, if called for, by making 

subsections based on the contrasting of noncalcic 

ilmenite and rutile with calcic tita:p.ite and perofskite; 

· each of these pairs being easily divided dichotomously 

in the same way~ 

- As the need of the. recognition ,of ~ub.m;ders seldom · 

arises, ~nd as they· are formed quite analogously to the 

:other divisions, th0y need not be further described.

RANGS. 

The ~ost general and the acidic characters ~f the 

. 'preponderant molecules having been used in making . 

: the preceding divisions, the relations of the basic 

radicals of the· normative mineral molecules are next 

considered for further divisions. These n1inor divisions are called rangs and subrangs, and in these divisions oxide molecules and not mineral molecules are 

dealt with. Rangs are established on the general 

· character of the basic oxide .. 

I~ the orders of .Classes I, II, and III the rangs are 

· based on the relations of total salic alkalies to salic 

lime-that is, the 1{20' +N a20' and CaO' of normative 

feldspar and lenad molecules. 

Salic alkalies comprise only those that enter into 

the molecules of normative orthoclase~ albite, leucite, 

· nephelite, kaliop.hilit~, halite, and thenardite; denoted 

:by K 20' and Na20'.· The K20 of Si0~ and the 

' N a20 of acmite and N a2Si03· are fernie and are denoted 

by K20" and N a20u. Salic lime (CaO') is only that 

which enters into the normative anorthite molecule. 

The lime (CaO) of normative 'diopside, wollastonite, 

c~lcium orthosilicat~, apatite, titanite, and perofskite

is femic (CaO"). · Stress n1ust be laid ·on this dis tine-: 

tion, as it has been overlo~ked by some ge.ologists, 

who have· in consequence incorrectly determined the 

classificatory positions of some rocks. 

In orders 3, 4, 5, 6, 7, and 8 (Classes I, JI, and III), 

the division is 'fivefold and is carried out with the same 

center points and limits as before. In order 3 the 

quartz is fLxed in composition, so that the division is 

applied to ·the chemically variable feldspars and 

lenads. In order 2, with subordinate .feldspar, the 

division is only threefold, but rocks that fall here are 

very rare. The divisions are defined as follows: 

Ra.ng 1 (peralkalic). Salic alkalies extreme over salic lime. 

Ra.ng 2 (domalkalic). Salic alkaiies doiD:inant over salic lime. 

Rang 3 (alkalicalcic). · Salic al:mlies a.nd salic lime equal. 

Rang 4 (docalcic). Salic lime dominant over salic alkalies. 

Ra.ng 5 (percalcic). Salic lime extreme over salic alkalies. 

In the orders of Classes IV and V the rangs are based 

·on the relations of total magnesia, ferrous oxide (not 

including Fe20 3 calculated as FeO), and Jemie alkalies 

(practically always N a20'') to Jemie lime, a practice in 

accord with a recently published modification of the 

classification.1 The divisions are as follows: 

Rang 1 (permiric). MgO+FeO+N~O" extreme over CaO". 

Rang 2 (domiric). MgO+FeO+N~O" dominant over Ca011 • 

Rang 3 (calcimiric). Mg0+FeQ+Na20" and CaO" equal .. 

Ra.ng 4 (docalci.c). CaQ" dominant over MgO+FeO+N~O". 

Rang-.5 (percalcic). Ca011 extreme over MgO+FeO+Na20": .. 

· .SUBRANGS. 

rrhe subrangs are based 01~ the relations of the oxides 

forming the. cmnpound to ~ne o_f the two contraste.cl 

variables that· are used for rangs. · In Classes I, II, and 

III these are salie soda (N a20') and salie potash 

(K20'). In rangs 1, 2, and ·3 the division is fivefold, 

as follows: .... 

· Subra.ug l (pet;potassic). K20' extreme over Na20'. 

Subrang 2 (dopotassic). K2 0' dominant over Na20'. 

Subrang 3 (soq.ipotassic). K20' and Na20! equal. 

Subrang 4 (dosodic). Na2<;Y dominant· over K20'. 

Subrang 5 (persodic). Na20' extreme over .1\20'. 

. In the docalcic rangs of Classes I, II, and III the 

division is threqfold. 'j. 

Subrang 1-2 (prepota.ssic). K20' preponderapt over N:a20'. 

Subr~ng 3 (sodipota.ssic). K20' and Na20' e·qual. 

Submng 4-5 (prosodic). Na20 1 prepondera.nt over K20 1 . 

In the. percalcic rangs 5 there is no division into 

subrangs; as the alkalies are l{egligible. 

· In Classes IV and V the contrasted factors are 

MgO and FeO +N a20". In rangs 1, 2,.and 3 the division is .fivefold, as follows: · · 

Subrang 1 (permagnesic). MgO extreme over FeO+Na20". 

Subrang 2 (domagnesic). MgO dominant over FeO+Na20 11• 

Snbrang 3 (magnesiferrous). · MgO and FeO+Na20" equal. 

Subrang 4 (doferrous). FeO+Na~O" dominant over MgO. 

Subrang 5 (perferrous). FeO+Na20'' extreme over JHgO.

. ·: In'the docalcic rangs 4' the divisiml. 'is ·threefold,' as 

described abo-ve·; and in the percalcic 1·angs 5 there·is 

no division into stibrangs.. . . 

· Ih ·a very few rocks the 'amount of fernie soda is so . 

great that recognition of the relative· amounts of FeO 

and N a20" is called for and is expressed in sections of 

subrangs, FeO preceding.: 

GRADS. AND SUBGRADS. 

In the divisions c'alled grads and subgrads and in 

sections of them are expressed the successively more 

detailed character of the subordinate normative molecule group in the various classes; the fernie in Classes . 

II arid III and the salic in Class· IV. These divisions 

are established precisely· as are the divisions frmn order 

to ~ubrang incl~sive, though not with the same detail, 

as the variables dealt with are· subordinate. In 

Classes I and V grads 'and subgrads are not called for, 

as the subordinate ·group is present in negligible 

:amount. Grads and subgrads are disregarded in this o 

Gollection of analyses, except that the symbols of the 

subordinate fernie divisions are given in Class III, 

Salfen1ane. . NOMENCLATURE. 

The nomenclature of the normative divisions of the 

classification is ,treated very briefly here. The names 

: consist of a root and· a· termination, the termination 

inP.icating the relative position of the named division 

in the system. The·terminations for the divisions are: 

Class (-ane). Subclass (-one). 

·order.(-are). , Suborder (-ore). 

Rang ( ... ase). S~brang (-ose). 

·Grad (-ate). Subgrad (-ote). 

· Sections of any of these divisions are indic~ted by inserting an "i" between the root and the termination. 

The roots of classes are mnemonic of the contrasted 

factors on which they are based, and the names of 

· the five classes are as follows: 

Class I. Persalane. Sal extreme over fern. 

Class II. Dosalane. Sal dominant bver fern. 

Class III. Sa.lfemane. Sal and fern equal. 

Class IV. Dofemane. Fern dominan~ over sal. 

Class ,V. Perfemane. Fem extreme over sal. 

The names for subclasses that were originally proposed '(persalone, dosalone, salfemone, ·dofemone, 

perfemone) are clearly incorrect and· unsystematic, 

and they must therefore' be rejected. They are ''in·-

correct and not properly mnemonic in that they are 

not based on the variables used to form subclasses, 

namely, (Q+F+L) and (C+Z) in Cla~ses 'I, II, and 

III and (P + 0 + ~1) and (A) in Classes IV and V; they 

are not precise in their applications, and they are unsystematic because other subclasses of the same class 

can not be formed analogously. Mnemonic systematic names, precise in their application, can be devised 

for subclasses, but they would be awkwardly long. 
1156 CHEMICAL ANALYSES OF IGNEOUS ROCKS. 

For example, adopting quafel as mne!llonic of QFL 

and corz as mnemonic of CZ, the name. of Subclass 

I of persalane would be perquafelpersalone; that of 

Suhclass III of persalane (cf. ·p. 325) wouid be quafelcorzpersalone; and that of Subclass II of salfemane 

(cf. p. 703) would be doquafelsalfemone. Subclass 

II of Class IV (p. 732) would thus be named dopomdofemone~ Similarly formed. mnemonic names for 

divisions below a subclass would become still more 

complex and unrqanageable; thus the . order cari.a-

. dare might be systematically and mnemonically 

called perlelperquafelpersalone. 

As the known representatives of subclasses . other 

than Subclass I are still very few, it will be as well, 

for the present, not to name subclasses. 

The names of most of the orders and suborders are 

based on the names of _countries and nations, 'and 

occasionally such roots are used for lower orders, 

but most of the roots of the rangs and· subrangs are 

o based on smaller geographic units. Many of the 

roots of the common rock names are also used. 

LIMITS AND SYMBOLS OF THE DIVISIONS. 

Figure 3 1 shows the p·ercentages and decimal ratios 

that determine the limits of the different divisionscentral, intermediate, distal~ and transitional-and 

the symbols that indicate them· as they have been. 

-'used in Part I of the ·collection (pp. 49-747). In 

Classes I, II, and III the ·perlelic order _5 is of the 

same extent as the other orders, but as it intervenes 

between qmp.:dofelic order 4 and lendofelic m:der 6, 

this particular division should be twice as long as 

it is represented on the scale, the scale being continued 

to include the succeeding orders.2 Any misapprehension of this· point can be obviated l?Y considering 

that the lenadic half of order 5 in Classes· I, II, and 

III is represented ~n the figure by ord~r I, order 6 

by order 2, order 7 by order 3, order 8 by order 4, 

and order 9 by the scalar half of order 5. This applies only to orders in Classes I, II, and III. 

It may be well to· give illustrations of 'the meanings 

of the several terms and· symbols that are used to 

indicate the relative position of a roc~· in a division 

of the quantitative system, reference being made to

CALCULATION OF THE NORM. 

INTRODUCTION.· 

Inasmuch as the exposition of the calculation of 

the norm in ·the quantitative system of classification 

and the tables of molecular numbers and percentage 

weights as originally published 1 may not now be readily accessible to all who use this collection of analyses, 

it has been thought that it would be useful to furnish 

these data in this volnme. 2 The republimttion of this 

matter is the more advisable because the original statement of the calculation· is very concise and because 

some changes have. been suggested since the matter 

was first published.3 A very clear and detailed state- · 

ment of the methods of calculation, illustrated by many 

examples and accompanied by the numerical tables, 

has lately been published .by Finlay.4 . . 

In the present wbrk considerable change has been 

made in the presentation of the calculation, though 

without altering its general principles, and the tables 

have been to some extent rearranged so as to make 

them more convenient forth~ ready calculation ofthe 

norms ·of the great majority of rocks. Some seqtions 

have been expanded and some contracted, ·as dictated 

by much· experience, and a few errors have been corrected. 

In the calculation of the norms of thousands of. analyses I have found that the formal way of setting down 

the data in columns, as proposed in the original publication followed by Finlay and generally used, in-

. volves ~orne needless repetition and waste of time. 

Thus in calculating th.e feldspars and lenads there is 

no need of repcuting for Al~03 the figures for K20, 

Na20, and CaO; or ill calculating magnetite of setting 

down the figures for FeO and Fe20 3, as they are necessarily identical. Mter several trials I have adopted 

and u~ed for some years the arrangement ~hown in 

figure 1 (p. 37). By adopting such an ar~angement, 

not putting down more figures ~han ~re .necessary, 

and with a little practice and experience, 1t will be found

. tativo classification of igneous rocks, pp. 180-203, 236;-259, 1903. •

thorn Prof. A. Lacroix, of Paris, and Prof. A. Johannsen, of Chicago.

that the calculation of a norm takes but little time. 

For most rocks five minutes should suffice, but when 

readjustments have to be made (as because of deficiency in silica) the ca1culation may take ten minutes, 

or fifteen at the outside, in the most complicated 

norms. 

The term molecular number 5 is adopted here, instead of the commonly and previously~ used molecular 

ratio, molecular proportion, or the term mol number, 

suggested by Wright and Van Orstrand,~ because of 

the following ·considerations: The word number is prefm·able to ratio or proportion because the result obtained by dividing the weight percentage of any given 

constituent by its molecular weight is a number which 

is independent aU:d irrespective of the other results 

similarly obtained. ·Thus, the result is not a ratio or 

proportion between such numbers. For rock analyses the· term molecular is preferable to mol, as the 

quantities involved are molecules and are not rel~ted 

to· any system of weights such as the definition of the 

term :inol implies. 

It is premised that in calculating the norm certain 

considerations should be borne in mind. The norm is 

the exp~ession of the chemical composition of the rock 

in terms of standard mineral molecules, a list of which 

is given on page 1163. Some of the constituents enter 

only into "fixed" molecules, which are so called because they are incapable of change, whatever be the 

gen·eral chemical character of the rock. Thus Zr02 

enters. only into. zircon (Z) as a, standard mineral, 

P20 5 into apatite (ap), 01 into.halite (hl), and so on. 

Other constituents may enter different mineral molecules according to the amounts of other constituents 

in the rock. Thus K20 rriay enter orthoclase, leucite 

or kaliophllite; and N a20 into albite or nephelite, ac-. 

cording to the amount of available Si02 • 

·As regards Al20 3, except when it is in excess of the 

sum of the alkalies and lime .C the excess forming the 

co.rundu1n molecule), it is invariably present in the 

ratio of 1: 1 with K20, N a20, or CaO in the salic minerals orthoclase, ·leucite, kaliophilite, albite, nephelite, 

and anorthite. Consequently~ where molecules of 

these miner~ls are considered in the following pages 

5 This term is used also by Finlay. . 

6 Wright an~ Van Orstrand, Wash. Acad. Sci. Jour., vol. 3, p. 223; 1913. 
.. i: · CALCULATION OF· TH.E NOR1\!J:. 1163 

n.ny mention of K20, Na20, or. :CaO implies the con-· 

sideration of an' equai molecular :amount of Al20 3 • 

$tress must also be laid on the fact that only the CaO 

which with an equal amount of Al20 3 .enters ·anorthite 

is salic. The excess of CaO over this is fernie. 

The adjustment of the Si02 is one of the most important features in the calculation of the.norm. The 

general principle followed involves· a recognition of the 

so-called a·flinity of the different bases for Si02 and of 

the relative proportions of Si02 to base which each 

base can bind.1 The order ?f affit?-ity for Si02 , by. 

whic4. the distribution of this constituent is determined in c~culating the norm, is as follows:, 

K20 >Na20 >CaO >MgO >FeO. 

It should be noted that this order is not arbitrarily 

chosen but is founded on experience in petrography 

and mineralogy, supported by laboratory experiment, 

and. that it acco):ds in general with the occurrence of 

minerals in igneous rocks. · 

Stress must also be laid O.t;l the fact. that· the socalled standai·cl minerals are undm~stood to be molecules and not actual minerals. The misappreciation 

of this point. has apparently led to some· confusion of 

mind in tegara to the norm. . ·

In solubility need not bo discussed hero. A general discussion of this subject and of 

tho norm will form tho subject or a separate paper. · 

Of· these molecules quartz, corundun1, sodium and 

pot~"Lssium metasilicates, he1.11atite, and rutile are what

. an excess of some ~onstituent over the .amount which. 

1nay be used to form other constituents. 

THE CALCULAT:ON. 

The fo.llowing statement of the rules .. for calculating' 

the norm is based on the original presentatio~, but is 

n1odified in substance to accord with certain suggested 

minor changes and is modifie~ in, f~rm so fa~ as to 

r~prese~t the procedure adopted by me in calculating 

the norn1s .found in Part I of the tables. In the 

description the word "amount" should always pe . understood to n1ean the molecular am,oun~ or the 

·molecular nun1ber obtained by dividing the percentage· 

weight of the constituent by its molecular weight. 

. 1. The molecular number (amount) of each constituent is determined by reference to the table of 

molecular numbers, given on pages 1166-1170. ·If the 

result is less than 0.002 it may be neglected. 

2. The amounts of :MnO and NiO are to be added to 

that of FeO, and those of BaO and SrO to that of c~. . . The minor fixed molecules are first to be clisposed of. 

The. order in which this is done (3a-3i) is generally 

immater~al. · · 

pa. All amount of CaO equal to3.33 that of the P205 

· is 8llotted for apatite. .. 

3b . .An amount of .N a20 equal to that of ~he Cl2 is 

allotted for halite. 

3c. An amount of N a20 equal to that of -the 803 is 

allotted for thenardite. It must be remembered here 

that the 803 stated in· the anfllysis often really repre-· 

sents the S of pyrite, so that rule 3c is applicable only·. 

when the rock contains minerals of the hauyne group. 

3}1. An a1nount of FeO equal to half that of S (or the. 

S of erroneously stated. 803 as above) is allotted for 

pyrite. 

. 3e. An amount of FeO equal to that of the Cr20 3 is 

allotted for chromite. 

· 3f. An amount of FeO equal to that of the Ti02 is 

allotted for ilmenite. If there is an excess of Ti02 an 

equal a1uoun~ of CaO is to be allotted to it for provisional titanite, but only after the allotment of CaO to 

Al20 3 for anorthite (Rule 4d). If there is still an 

excess of Ti02 it is calculated as rutile. . 

3g. An amount of CaO equal to half that of the F 

in excess of what is needed. for apatite (th~t is, the 

0.33 of. CaO of 3a) is allotted for fluorite. 

3h. If .the rock is not decomposed and contains· 

earicrinite, an a:rp.ount of N a20 equal to that ·of. the 

C02 is allotted· for soclium carbonate, which is to be 

con~~dered as salic.1 If the rock contains calcite, an 

amo'unt of CaO equal to 'that of the C02 is B;llotted 

for calcite. If the modal calcite is primary, this 

normative calcite molecule is to be regarded as fernie; 

1 'l'his is a recent modification, seep. 31. 
1164 CHEMICAL ANALYSES OF IGNEOUS ROCKS. 

if the modal calcite is secondary or ·due to the assimilation of limestone, the calculated calcite molecule· is 

to be disregarded as not forming part of the. norm. 

. 3i. An amount of Si02 equal to that of the Zr02 is 

· allotted for zircon. . 

Of the allotments under Rule 3, only a ~nd f are 

generally and b, c, and i occasionally necessary; the 

others are rarely milled for. 

4a. An amount of Al20 3 equal to that of the K20 is 

allotted for provisional orthoclase. 

4b. If there is an ·excess of K20 over Al20 3 (an 

excess extremely rare), it is calculated as potassium 

metasilicate. _For the Na20 see Rules 5a and 5b. 

. 4c. An excess of Al20 3 over the K20' is· allotted to 

an equal am9unt of remaining N a20 for provisional 

albite. If there is insufficient A120 3 , see Rul~ 4g. 

4d. If there is an excess of A120 3 over the K20 + 

Na20 it is allotted to an equal amount of remaining· 

CaO for anorthite. 

· 4e. If there is an exoess of Al20 3 over this CaO it is 

calculated as corundum. 

4f. If there is ~n excess of CaO over this Al20 3 of 

4d it is fernie and reserved for diopside and wollastonite. (See Rules 7a and 7b.) 

4g. If· in 4c there is an ·excess of N ~0 over Al20 3 

it is to be reserved for acmite and possibly for sodium 

metasilicate. (See Rules 5a and 5b.) There is then 

no anorthite in the norm. 

. 5a. An amount of Fe20 3 equal to that of the excess 

of N a20 o.ver A1 20 3 (see Rule 4g) is allotted to acmite. · 

· 5b. If there is still ·an excess of N a20 _over Fe20 3 

(a rare excess) it is calculated as sodium metasilicate. 

5c. If,· as usually happens, there is an excess of 

Fe20 3 over Na20 it.is assigned to magnetite, an equal 

amount of FeO being allotted to it out of what remains 

from the formation of pyrite, chromite, and ilmenite. -

(See Rules 3d, 3e, 3f.) 

5d. If there is still an excess of Fe20 3 it is calculated 

as hematite. 

6. All the MgO and the FeO remaining from. the 

previous allotments (see Rules 3d, 3e, 3f, and.5c) are 

added together and their relative proportions are ascertained (most easily by the use of a slide rule). 

·7 a. To the amount of CaO from 4d is 'allotted provisionally an equal amount of MgO + FeO · to form 

diopside, the relative proportions of these two being 

preserved .. 

· 7b. If there is an· excess of CaO it is reserved for 

pr0visional wollastonite. 

7 c. If there is an excess of MgO + FeO over that 

needed for diopside (7a) it is reserved for provisional 

hypersthene. 

All the oxides except Si02 have now been assigned 

to actual or provisional mineral molecules and we have 

next to consider the distribution of the silic·a. 

Sa. The sum of the amounts of silica needed to form 

zircon from Zr02 (Rule 3i, 1 :1), titanite from CaO 

(Rule 3f, 1 :1), acmite from exce~s Na20 (Rule 5a, 4:1),. 

potassium and sodium metasilicates from excess ~0· 

and. Na20 .(Rules 4b, 5b, 1 :1), and provisional orthoclase from K20 (Rule 4a,· 6:1), albite from Na20 

(Rule 4c, 6:1), anorthite from CaO (Rule 4d, 2:1), 

diopside from CaO + (Mg, Fe)O (Rule 7a, 1 :1), wollastonite from excess CaO (Rule 7b, 1 :1), and hypersthene 

from (Mg, Fe)O (Rule 7c, 1 :1) is subtracted from the 

total Si02 • 

Sb. If there is an excess of Si02, as there commonly 

is, it is calculated as quartz. 

Sc. If there is a deficiency of silica in Sa the Si02 

allotted to hypersthene (Rule 7c) is subt.racted frorn 

the general sum of Sa and the remainder subtracted 

from the total Si02• If there is here an excess of 

Si02 it is allotted to the (Mg,Fe)O of 7c to form 

hypersthene and olivine, and is distributed according 

to equations (1) and (2): 

Let x =.the number of hypersthene molecules and 

y=the number of olivine molecules, then-

(1) x+y=the amount of available (Mg, Fe)O and 

(2) x+~=the amount of available Si02 • 

In this operation the relative proportion of MgO and 

.FeO determined. in 6 and used in forming diopside 

(Rule 7a) is to be preserved. The fixed and provisional molecules of ·Rule Sa are calculated into· their· 

·percentage weights. If there is not enough silica to. 

equal half the amount of (Mg, Fe)O of Rule 7c, all the 

(Mg, FeO) olRule 7c is calculated as olivine, Si02 equal 

to half its. amount being assigned to· it. 

Sd. If there is a deficiency of Si02 in 8c, the Si02 

allotted· to titanite (3f) is subtracted from the general 

sum of Sa, and the CaO + Ti02 calculated as perofskite. 

To follow strictly the order of affinity for Si02 

stated on page 1163 we should now distribute Si02 

between wollastonite ~nd calcium orthosilicat~, but 

as calcium orthosilica~e is represented modally-that 

is, among actual minerals-in igneous rocks only in 

the very rare melili~e, which also always occurs in 

rocks containmg little Si02 and abundant nephelite, 

little albite, and often considerable leucite, we next. 

take up the distribution of Si02 between albite and 

nephelite as representing most closely .the facts of 

actual mineral occurrence. 

Se. The sum of the Si02 needed to form the molecules of Sa is deducted from the total Si02, except that . 

olivine is substituted for hypersthene, and perofskite 

for titanite, and that albite is not included. If there· 

is an excess of m?re than twice (and, of course, less. 

than six times) that of the Na20 for the provisional· 

albite .of Sa this is distributed between albite and . 

nephelite according to equations (3) and (4): 

Let x =the number of albite molecules and y =the. 

number of nephelite molecules, then- · 

(3) x+y=the amount of available Na20, and 

(4) 6x+2y=the amount of available Si02• 
CALCULATION OF THE NORM. 1165 

Sf. If there is still a deficiency of. Si02-that is, in 

:se, not enough to equal twice the amount of available 

'Na20-all'this Na20 is allotted to nephelite and the 

K:aO is distributed between orthoclase and leucite, as 

follows: The sum of the Si02. needed for the molecmes 

in· Sa is subtracted from .the total Si02, olivine being 

·substituted for hypersthene, perofskite for· titanite, 

and 'nephelite for . albite, and orthoclase being disre-

.garded. If there is an excess of more than four times 

(and, of course, less than six times) that of K20 it is 

distributed between orthoclase and leucite according 

to equations (5) and (6) :· 

Let x=the number of orthoclase molecules andy= 

the number of leucite molecules, then-

(5) x+y=the.amount of available K 20, and 

(6) 6x+4y=the amount of ava~lable Si02 • 

Sg. If there is still a deficiency of Si02:_that is, m 

Sf not enough to equal Jour times the· amount of 

K 20-we have to distribute the CaO of wollastonite 

and diopside between these t~o and calcium orthosil-

. ' icate, and the (Mg, Fe )0 of diopside between diopside 

and olivine, according to the available Si02 • This 

distribution is made as shoWJ1, below. 1 There are two 

possible cases; either there is sufficient wollastonite to 

reduce to orthosilicate or there is not. 

The most frequent case is that in which there is no 

wollastonite or its amount is .insufficient to satisfy 

the deficiency in Si02• Here, after allotting Si02 to 

form leucite,. nephelite,. anorthite, acmite, olivine of 

rule 8c, and possibly zircon and sodium metasilicate, 

the amount thus used is deducted from the total 

Si02 , the residue being the·" available silica." Letting 

d =the number of new diopside molecules, f =the 

number of new olivine molecules, and c =the number · 

of calcium orthosilicate molecules, we have the equa-. 

tions-

(7) 2d+f +c=the amount of available Si02• 

(S) d +2f =the amount of (Mg,Fe)O (of provisional 

diopside). 

I Washington, H. S., Wash. Acud. Sci. Jour., vol. 5, p. 346, 1915. 

(9) d + 2c = the amount of CaO of provisional diopside 

and wollastonite. o . 

These equations can be sOlved, of course, in several 

ways, but that which I ·have adopted is as follows: 

Subtracting (7) from the sum of (8) a~d (9) we get the 

value of f + c; substituting this in .(7). d is found, and 

then from (8) and (9) f and c are found successively. 

In the second case, where there is sufficient tentative 

wollastonite to meet the deficiency of Si02 , the total 

amount of Si02 in the rock is subtracted from the sum 

of the Si02 which has been allotted to leucite, nephelite, 

anorthite, acmite, diopsid·e, olivine, and to tentative 

wollastonite. The deficit is the number of molecules 

of necessary calcium orthosilica te, and also the amount · 

of Si02 to be assigned to it. This requires twice as 

much. CaO. The rest of the CaO remains in wollastonite and takes an equal amount of Si02, while the 

diopside remains unchanged. 

8h. If, as may ~ery rarely happ~n, there is not even 

enough Si02 _to form leucite, we must assume the 

presence of the kaliophilite moleGule in the norm and 

distribute the K20 between this and leucite. For this 

the sum of the · Si02 needed for nephelite, anorthite, 

acmite, sodium metasilicate, olivine, calcium orthosilicate, and zircon is subtracted from the total .Si02 , 

and the amounts of leucite and kaliophilite are calcu~ 

lated according to the followiJ?.g equations (10) and 

(11) :' 

Let x~the number of ·leucite molecules and y=the 

number of kaliophilite molecul'es, then-

(10) x + y =the amount of K20, and 

(11) 4x+2y=the amount of available Si02 • 

9. Having thus adjusted the amounts of the Si02 , • 

and all the other constitu'ents between the fixed molecules and those with differing· ratios of Si02 (the provisional becoming actual molecules), they are calculated into the percentage weights of the mineral molecules of the norm by the use of the tables on pages 1172-

THE INDEXES. 

PREFATORY NOTE. 

Bocu.uso of the typographical arrangement of tho 

tables a page reference to the part of this work that 

is covered by therri implies also the opposite page, · 

hoth pages bei11g considered together. The odd-

~nrmbered (right-hand) page is the one generally 1'(rf'erred to, as on this page apPear the rock name, 

locality, reference, and other details. 

The title "Index to new rock names," formerly used, 

l.lfl.S been changed to "Index to normative names" to 

emphasize the fact that the names of the divisions of 

tJ·.o quantitative systen1 are not names of rocks b~t 

dosignate the chemical and standard mineral characters that are embraced in the term "normative." 

Also the word old has been omitted from the former 

title "Index to old rock names," as this adjective is 

inapptopriate in view of the present general use of 

these names and because such names are now being 

given to rocks a.nd will doubtless continue to be given 

to them in the future. · 

'rhe "Index to the text," which ·includes the index 

to the appendixes, has been made very detalle.d, possibly too much so; ·but it has been thought better to 

err on the side of including too much rather thai1 too· 

little. The· "Index to normative names" includes 

all names· that have been proposed, so far as k11own, 

up to 1917 ... Those that have been accepted and ar~ 

used in Part i of the tables are followed by their symbols, which show _their n1agmatic positions. Those 

that have been rejected and not so used are printed 

in italics. They aro discussed on pages 34-36. 

In tho "Index to rock names" and the "Index to · 

localities" the page numbers that refer to Part I. of 

the tables are separated by a dash (-) from those 

th~t refer to the other parts. Tho page numbers that 

ref or to Part IV (inferior analyses) are printed in 

italics. It may be well to mention that if a rock or 

locn.lity name is not found on tho page given in the 

index it n1ay possibly be found on the succeeding (oddnl.unbered) pag~. 

In the "Index to rock names" mineral qualifiers 

have been omitted where the qualifier would Imply 

no especially important or interesting magmatic or 

mineralogic character. Thus biotite. midesite and 

hon1blende andesite are to b.e looked for under andesite. 

Olivine basalt and olivine gabbro are indexed under 

basalt and gabbro, respective~y. Granitite is to ·be. 

looked for under granite. If, however, the mineral 

quulifier indicates a peculiarly interespi1:g or unusual 

mn.gmatic or modal character, or if the mineral mentioned is of rare occurrence, the qualifier is retained,\ 

as in the names of aegirite granite, analcite basalt,· 

cancrinito syenite, magnetite basalt, and quartz basalt. 

The mineral qualifier is of course retained in such names 

as nephelite syenite and quartz diorite. , Textural qualifiers are usually omitted fro¥' t)le.i:hdex;· for example, 

andesite porphyry will be found,undAr andesite', though 

·granite porphyry and diorite p(~rph'Jry are retained. 

In using this index the existence of many synonyms 

s};tould be borne in mind. Thus some rocks that mightbe called liparite may be found under rhyolite, some 

dolerites under 'basalt, and vice versa. The French 

labradorites are also indexed under basalt. _The usage 

of the terms" porphyry" and" porphyrite" in the liteta ture has not been uniform, and the two are frequently 

interchanged. In the index these names imply that 

~o mineral qualifier is used by the describer· or that the 

qualifier is the name of a cmnmon mafic mineral, such 

as augite, biotite, or hornblende. ·Quartz porphyry 

is retained in tho index. Such textural terms as 

obsidian and pUmice (indexed alone) imply that no 

qualifier has been used by the describer· of the rock. 

A "trachyte obsidian·" or "rhyolite ·pumice" is to be· 

'found under these full terms, respectively. 

Inclusions (such_ as "segregations" and "secretions'') and schlieren are indexed both under the name 

of the inclosing rock and under the terms "inclusions" 

and ".schlieren," as ·they may be of special interest fot 

some investigations. The few analyses of rock frag-

:rp.ents brought up from the ocean floor are ·also 

indexed collectively under the term" dredged blocks." 

The "Index to localities" has been the subject of 

considerable thought and consultation. The convenience of the petrologist, rather than cons.istency, 

has been the. chief consideration. The attempt has 

been made "to keep together., so far as possible, page 

references ·to analyses of rocks that occur in the same 

district or analyses that are given in the same paper. 

Arrays of figures such as are given in the first edition 

under Italy, California; and Mo-ntana, and sw:~h as 

would be very much n1ore numerous in the present 

work, which contains three times as 1nany _analyses, 

would be inconvenient and of ve.r;y little use, consuming 

. much time in looking up an analysis and hiding_ many. 

petrographic or bibliographic relations. To obviate 

this objection the present index -has been prepared 

in much greater detail, and i:Jl. general a distriet or 

locality is ·indexed separately if it is represented on 

three or more pages. · 1181 
1182 CHEMICAL ANALYSES OF IGNEOUS ROCKS. 

The primary grouping is by. countries, colonies, and 

detached or oceanic islands. Under countries and 

colonies the arrangement is to a large extent by States, 

Provinces, and such political subdivisions, thougl?- here 

the selection. is n.ot always that of a present-day 

political division, such as Scania in Sweden and 

Auvergne and Brittany in France. ·The colonies 

. that fo)'m the Australian Federation are indexed 

under Australia, but those that now form the Union 

of South Africa are ind.exed separately. 

For some countries-such as G~rmany, Italy, and 

Sweden-there is a primary subdivision into 'both 

political divisions and petrographic districts· on an 

. equal footing. The political divisions and geographical nomenclature of Germany especially are so complex, and the ·analyses of rocks from that country are 

so numerous, that. it has . required special treatment. 

A district or a .mountain group that lies wholly ~thin 

one German State is . treated as a subheading under 

that State, as, for example, the Hegau and the Kaiser~. 

stuhl, which are subheadings under Baden. On the 

other hand, such districts as tlie Harz, Lausitz, and 

Odenwald, which border on or form part of several 

provinces and -are petrographjcally important and· 

well known,· are given separate main headings. The 

Vosges are .referred to France and the Erzge birge to 

Germany. Some countries and States proved to be 

no.t "readily subdivided or are represented by too few· 

analyses to justify their subdivision. A further· subdivision of States or Provinces into petrographic or 

mining districts is n1ade if it seems to be called for in 

assisting reference. · 

If a country or State is subdivided-~nto districts, tho 

districts are given in alphabetic order, closing with 

the heading ''Miscellaneous,''· under which are placed 

. the page references to analyses from localities not thus. 

separately grouped. As fll.Y detailed knowledge of 

many regions is inadequate, ·and as time was lacking 

for reconsultation of many papers, it may be well for 

a petrographer who is seeking all the analyses of a 

district to consult also the "Misc'ellaneous" list. 

The treatment of the islands offered some peculiar 

problems. In general, islands that lie near the coast 

of a country to which they belong politically are indexed- as subheadings under that country. Thus, the 

. Channel Islands, The Isle of Man, and the Orkney 

Islands are subheadings under Great Britain; Corsica is a subheading under France; and the Aeolian 

Islands, Capraia, Elba, Sardinia, and Sicily are sub-

.headings- under Italy. Pantelleria and Linosa, however, are indexed separately. The islands in the. 

Aegean Sea, whatever their. past or present political 

status, are indexed under Greece, with the subheading 

Aegean Islands. 

Oceanic islands and those that are widely detached 

from the country to which they belong (such as the 

Bermuda, Galapagos, and Juan Fernandez islands) 

are indexed separately. The name of the ocean in 

which they lie is added when they are small or are 

little kno~, to facilitate-study. of petrographic provinces. Th~ ·small islands of the Malay Archipelago 

(such· as Ambon, Bawean, Flores, and Timor) are 

also indexed separately, on an equal footing with 

Borneo, Celebes, Java, and Sumatra, the term "Malay 

Archipelago" being appended to them.
