The Goldfield news. [volume] (Goldfield, Nev.) 1904-1911, 1908-12-12
Strikes and tSructure


Goldfeld is in the vicinity of an old
volcanic eruptive site which broke
through at a point of structural weak
ness along the Nevada fault zones.
After their eruption the rocks were in
turn fractured so that Goldfeld is now
an area of numerous cross faults and
fractures in many directions making
favorable intersections, fracturelets and
other channels for the upward eircula-
ton of the volcanic vapors which con
tinued to ascend long after the coun-
try rock was laid down, and accom-
plished the alteration and mineraliza-
ton of the rocks.
According to Collins, Gin the Combi-
nation, the general course of the silici-
fed zone is northwest southeast, while
the average course of the richer streaks
is nearly north south. These north
south seams do not extend into the
country rock for more than a few feet
beyond the limits of the siliciieation.
Where the lode has been rather more
shattered than usual and has, therefore,
offered a better channel for the miner
solutions, the oresboots may in
elude the whole silicifed material

fragments Of dacite, the inner crust be
ing usually the richer.
1.-THE following minerals have been
observed in the Combination mine, the
names being quoted in the order of
their Importance. In the oxidized zone,
quartz, kaolin, iron pyrite, gypsum,
hydrous ferric oxide, alum, some silvery
scales of a mineral that gave blowpipe
reactions for bismuth oxide, and small
quantities of a tellurite of iron. Near
the water level, ferrous sulphate. In
the snlphide zone, k%aolin, iron pyrite,
marcasite, t~etrahedrite, bornite, bis
muthinite, and very small quantities
of chalcopyrite and zine blende. The
gold is accompanied by a small proper
ton of silver.
"Of these minerals, the tetrahedrite
and the bornite are particularly import
ant as being intimately associated with
the gold. Free gold is often seen mixed
with the cupriferous sulphide, but even
when this is not the ease, and no gold
can be seen under the powerful glass,
the specimen will almost invariably as
say exceedingly rich in gold; from
which it is presumed that the gold is
either chemically combined with the
bornite and tetrahedrite, or else pres
emit in a very fine state of division.
"Gypsum, while not known with
actual sulphide ore, is very abundant
in the altered rocks within 100 feet or
so from the surface, and does occur
crystallized with quartz and pyrite on
the Goldfeld-B Belmont mine, below the
belt of oxidation.
"The brownish, copper bearing min
eral, here Professionally called tetrahe-
drite, contains anthony and sulphur,
as chemically determined by DR.. w. I.
Schaller, and is, therefore, not bornite,
although it goes by that name in the
district. 1t appears so commonly as a
constituent of the best ore that there is
a strong suggestion that it is auriferous,
particularly as the microscope fails in
some specimens of reputed rich ore to
reveal any free gold. Further investi-
CATION of the mineral is in progress.
"The proportion of silver is rather
small, the average of "a assays of rich
ore from the Mohawk mine, made for
j. w. Finch, giving $50 fine ounces of
gold and 46.5 ounces of silver to the
ton.
"Tests and chemical analyses of the
ores made for scientific and technical
purposes nearly all show a little tel
lurium, although no tellurium mineral
has been recognized in the mines close
to Goldfeld.'
The Goldfield news. [volume] (Goldfield, Nev.) 1904-1911, 1908-12-12

"The absence of sulphate from ron
tact ore deposits indicates, however,
that oxygenated sulphur compounds are
not given off directly from solidifying
magmas.
whether the solutions were notably
ferruginous is doubtful. As compared
with other districts, the pyrite at Gold
field is not abundant, and all of that in
the country rock can, as has been
shown, be accounted for without any
addition of iron. There has, in fact,
been an abstraction of iron which may
have been sufficient to form the pyrite
in the actual ore, upon the superstition
that the dissolved iron, like the silica,
migrated toward the assures

phenocrysts of the dacite still retain
their characteristic s~embayed' outline
when the rest of the rock is altered to
quartz alunite and kaolinte.
"Large masses of cooarsely crystal.
line vein quartz are absent from this
district and it seems necessary to con-
clude that the ~ore-bearing solutions
were not only poor insilica, but that, in
spite of their energetic attack upon the
rocks, they were not good solvents for
quartz.
"The quartz set free by the decompo-
sition of the s~ilicates has for the most
part re~crystallized as fine grained az
gregates, constituting the hornstone-
like quartz
The Goldfield news. [volume] (Goldfield, Nev.) 1904-1911, 1908-12-12
The County Rocks

At Goldfeld the country rocks con-
sist of volcanic intrusions and eruptions
of tertiary age, cutting through and
overlooking a plexus of older sedimen-
taries and surrounded by desert wash;
and at both localities the introduced
gold occurs in kaolinized or Admitted
''porphyries'' of the andesitic family.
The ores of Goldfeld occur in middle or
early tertiary rhyolite, latte, andesite
and dacite. Nearly all of these are ex-
trusive flows, or intrusions.
At Goldfeld the ores are largely in an
intrusive sheet of dacite, a rock species
at the silicious extreme of the andesite,
although Collins asserts that the ores OF
the Little Florence are in andesite. 1t
is very difficult for the layman to dis
tinguish dacite from andesite; in fact,
dacite is merely andsite containing free
silica and, in the classification of rocks,
is near the boundary between andesites
and rhyolites. The field worker in Ne
vada who encounters either of these
rocks intensely altered, as they should
be if they contain gold or silver, will be
lost in distinguishing them, except In
some locality where their aspects have
been pointed out after microscopic
search

The Mineral Alunite

Associated with the quartz in much
of the ore at Goldfeld are soft white
substances such as the miners commonly
call "talc," "kaolin," etc. Chemical
and microscopic tests of the white ma
terial, as made by DIR. Ransome, show
that in most cases it is either alunite or
kaOlinite, or a mixture of the two.
Alunite, a rare and seldom found min
eral, is a decomposition or alteration
product of the feldspars of igneous
rocks, acted upon by hot s~ulphurous vol
canic vapors penetrating the rocks from
~deep-seated volcanic magmas. Alunite
is a hydrous ~sulphate of potassium and
aluminium with the fomula K2O 3Al2O2
4SO3 6H2O. Concering this mineral
Ransome says:

Departure From Precedent
Some of the ways in which the ores
differ from the previously known ore
occurrence are as follows: (1) The ores
do not occur in mountains, but are
found in eroded valleys between the adj
jacent mountains. (2) There are no
strong iron outcrops. (3) Coarse quartz
veins and well defined true assure veins
are conspicuously absent. az The ores
do not outerop strongly at the surface.
(5) 1t is usually difficult, except in ex-
ceedingly "high grade to tell ore
from country rock. (6) 1t is very diff
ficult to detect or tell the average ore
at all, except by panning, and not al
ways by the latter method.
As worked out and discovered by DIR.
Ransome the Goldfeld ores are clear ex-
amples of deposition or replacement in
a favorable matrix by acidic, gold
bearing, so~lfataric vapors, which, pene-
trating the igneous rocks from below
through assures, deposited or dissemi-
mated the gold in the adjacent country
rock coincidently as they altered the
feldspars into %alunite and kaolinite.
As stated by Ransome: "The recog-
milton of ~alunite as a characteristic con
stituent of the Goldfeld ores and the
demonstration of it's genetic relation to
them establishes a new type, that of
'%alunitic and koalinitis gold quartz
veins While the Goldfeld deposits are
too irregular in form to come under the
usual definition of vein, yet they have
the same genesis as what is usually
termed a metasomatic replacement fs-
sure vein, j. e., values disseminated
throughout the country rock adjacent
to the assures The key to the pecu-
liar occurrence of the Goldfeld ores is
the fact that the Undertaking vapors
were acidic and nonferruginous, in
stead of alwaline and ferruginOus, as
in previously recorded instances, result
ing in different aspects of alteration
and alteration products in the country
rock, and the absence of or feebleness
of iron stains.

(By Robert T. Hill in the Engineering
and Mining J~ournal.)
Goldfeld is sui generis in that mo-
where else, not even in Nevada with its
many gold camps, until recently, has
another locality of a similar geological
type of ore occurrence been discovered.
Every natural condition of topography,
outcrop, country rock, and of other Gin
dications' considered by the prospec-
tor, is different from those with which
precendent is familiar. 1t is safe to
say that had not the ores been discov-
cred accidentally a great majority of
prospectors, practical mining men, geol-
ogists and engineers would today pass
over the ground without thinking it
worthy of serious consideration.
The Goldfeld ores are a conspicuous
example of ores occurring in a manner
entirely different from any known pre-
cedent. They are neither true filed fis-
sure veins, magmatic s~egregations, nor
contact deposits. The aspects and
principles of the Goldfcld type of ore
occurrence have recently been worked
out and defnded by DIR. +. Leslie Ran
some, of the United States Geological
survey. These principles are so abso-
lutely different from precedent that we
believe that DIR. Ransome's results and
conclusions, which make one of the
most important contributions to the
geology of ore deposits whoch has APP
peared for years, should be available to
