GEOLOGIC NAMES OF THE UNITED STATES THROUGH 1975

By Roger W. Swanson, Marilyn L. Hubert, 

Gwendolyn W. Luttrell, and Virginia M. Jussen

INTRODUCTION

This report lists most of the rock-stratigraphic geologic names 

in published use in the United States and the major elements necessary for their definition. The format is based on a modified form of 

the Standard Stratigraphic Code adopted by the American Association 

of Petroleum Geologists, Committee on Standard Stratigraphic Coding 

(1967), to which was added other information critical to definition 

of geologic names. The report was prepared primarily from U.S. Geological Survey lexicons (Wilmarth, 1938; Wilson and others, 1957; 

Keroher and others, 1966; Keroher, 1970; and Luttrell and others, 

1981), library research, and data in the files of the Survey's Geologic Names Committee; it also incorporates information supplied by 

State Geologists.

The name usage and accompanying data are based primarily on information published before the end of 1975, but age revisions recorded in the Geological Survey file of accepted usage before the end of 

1975 and published later are included. Compilation is continuing on 

names introduced or otherwise modified since 1975. The interval between cutoff date and publication of this list reflects delay in 

availability of published material, difficulties in reviewing and 

processing the large amount of information, and problems of adjusting 

conflicting data. More recent information on changes of names that 

are in use by the U.S. Geological Survey, and on new names, may be 

obtained from U.S. Geological Survey Bulletins 1U35-A, 1157-A, 1H82- 

A, and 1502-A (Sohl and Wright, 1977, 1978, 1979, 1980).

Because this list has been prepared primarily for the benefit of 

geologists of the U.S. Geological Survey, who will be able to consult 

it via a computer terminal, emphasis has been placed on information 

recorded in the Survey files or obtained by consultation with Survey 

personnel. Where a difference exists between Survey records and data 

more recently published by others, the Survey file may be updated as 

necessary; however, the principal means of updating the Survey file 

of accepted usage is through Survey manuscripts submitted for review, 

wherein the need and justification for change can be documented. The 

authors of those reports, who are familiar with the details of the 

geology involved, can best recommend changes but should be able to 

demonstrate the need to their peers (reviewers) as well as to the 

Geologic Names Committee.

2 GEOLOGIC NAMES OF THE UNITED STATES THROUGH 1975

Official State usage as recorded in recent State reports, geologic maps, and lexicon-type publications is reflected insofar as 

possible. Information was obtained from State Geologists, who responded to the preliminary version of this list, which was distributed to them.

ACKNOWLEDGMENTS

Preparation of this list of geologic names was accomplished with 

the help and guidance of George V. Cohee and, since Mr. Cohee's retirement, of Norman F. Sohl, successive Chairmen of the Geologic 

Names Committee of the Geological Survey. Their helpful advice and 

encouragement have been of great value and are very much appreciated. Many others in the Geological Survey have supplied valuable 

information and counsel, including particularly Claire B. Davidson, 

Rudolph W. Kopf, Marjorie E. MacLachlan, and Wilna B. Wright of the 

Geologic Names Committee staff; the staff assistance of Susan 

Kingsbury is much appreciated.

Preparation of the original computer list of names was accomplished with the help of Linda E. Deiter and Olaf Kays of the Geological Survey. Subsequently, Patricia A. Fulton and Kevin W. Laurent, 

also of the Geological Survey, have been particularly helpful in 

writing programs and providing guidance for the computer manipulation 

of the data in this printout.

CODE OF STRATIGRAPHIC NOMENCLATURE

Geologic names should be established or revised according to the 

guidelines set forth by the American Commission on Stratigraphic Nomenclature (1970) in its "Code of Stratigraphic Nomenclature," hereafter referred to as "the Code." The U.S. Geological Survey has been 

a strong supporter of the Code as a means of achieving a more meaningful application of geologic names to mappable rock units. Application of the Code is not always easy or clearcut, for rocks are 

variable in all dimensions, and the Code does not clearly address 

some problems, but the decisions in selection of names for this list 

have been made with the Code foremost in mind. Though minor revisions 

have been made in the Code in recent years and though a major revision is in progress, this list reflects the Code that was in force at 

the end of 1975.

Many published usages of geologic names are at variance with the 

Code, and the resultant problems must be addressed in preparing a 

list such as this. Some of the differences reflect usages that antedate the Code and have persisted; some reflect problems not fully 

addressed by the Code, or even inconsistencies within the Code; and 

some seem to reflect ignorance of the Code as it might apply to the 

problem at hand.

In this effort to prepare the most meaningful list of geologic 

names that is practicable, deviation from the Code is avoided where 

possible. Thus, where a choice in name usage based on more than one 

publication is available, the usage in agreement with the Code is selected. Where such a choice is not available and a problem exists in 

the name, a slash (/) is entered immediately before the name to flag 

the existence of a problem. Problems such as multiple usage, adjec-
GEOLOGIC NAMES OF THE UNITED STATES THROUGH 1975 3

tive in name, improper rank combination, misuse of the term "series," 

rock body terms, and preemption are subject to the slash.

For some names, a rank term has been omitted by the author but 

is clearly inferred, such as a limestone in a formation. Omission of 

the term "bed" or "member" implies one formation within another, 

clearly an error, so the rank term must be added, for example: 

ALBRIGHT,LS [BED] (CONEMAUGH FM). We slash a name that is in violation of the Code and enter one that is appropriate, but all information inserted by us is enclosed in brackets, for example: 

/PLACKSTONE.SER and [BLACKSTONE.GP].

DATA AND EXPLANATION

The format used in this list is based on the recommendations of 

the American Association of Petroleum Geologists, Committee on Standard Stratigraphic Coding (1967). Each line (record) in the list 

represents a separate name usage and is not duplicated by any other 

line. For some name usages, two or more lines are necessary to reflect the geologic age range, and each usage in each State is noted 

separately. A line may contain the following information: State, 

geologic age (coded), geologic name, usage, lithology, color, thickness, type area, reference, and identifier. The last five items before the identifier are noted only for the first line of the typelocality State. The items are explained separately.

State. The State in which the unit has been identified is noted 

by the two-letter U.S. Postal Service abbreviation, as follows:

Geologic age. The geologic age is represented by a three-digit 

number. The first digit represents the erathem, the second, the system, and the third, the series. In addition to the numbers established by the Committee on Standard Stratigraphic Coding, we have 

added 01, OU, and 07 to each of the erathem numbers, except that for 

the Precambrian, to reflect informal subdivisions upper, middle, and 

lower, respectively. To the Precambrian erathem number (1) we have 

added 10, 20, 30, and 10 to reflect the fourfold division of the 

Precambrian (Z, Y, X, W) that was in use by the U.S. Geological Survey in 1975. The time breaks between these intervals are 800, 1,600,

The provincial series coded in this report, flagged above by footnote 

numbers, apply to the following States:

J/ Alabama, Arkansas, western Florida, Louisiana, Mississippi, 

southern Oklahoma, and Texas

2J Alabama, Arkansas, Louisiana, Mississippi, and Texas

3/ New Mexico and Texas

JL/ Arkansas, Illinois, Iowa, Kansas, Missouri, Nebraska, and 

Oklahoma

5/ Illinois, Indiana, Iowa, western Kentucky, Missouri, and 

western Tennessee.

The other provincial series used in the United States have not been 

coded in this report because they are essentially synonymous with the 

standard series.

Where geologic names apply to rocks whose geologic age extends 

into more than one series or system, a separate record is provided 

for each age. A plus sign (+) follows the first or youngest such age 

to alert the reader to read farther for full age information. When 

the geologic age of rocks is so imprecisely known that the rocks cannot be assigned to any one system, it may be possible to identify 

them with the upper, middle, or lower part of an era them. For such 

rocks, the 01, 04, and 07 divisions of erathems have been added.

Age coding of the Miocene, which has boundaries at 22.5 and 5.0 

million years, is based on Berggren (1972). Guadalupian names are 

all coded 313 and Morrowan names are all coded 328, even though some
6 GEOLOGIC NAMES OF THE UNITED STATES THROUGH 1975

Guadalupian units include Lower Permian and some Morrowan units include Middle Pennsylvanian strata.

Geologic name. As stated in the Code, "The formation is the 

fundamental unit in rock classification." In this list, therefore, 

every record includes reference to one rock unit of at least formation rank. The primary unit is listed first, the geographic name being separated from the rank or lithology by a comma. The next larger 

unit, of which the primary unit is a part, is noted in parentheses; 

that notation may include two larger units in order to reflect formation rank. For example, a named bed as the primary unit may be in a 

member that must be part of a formation. If the primary unit is less 

than formation rank, nothing higher than formation rank is noted. If 

the primary unit is of formation or higher rank, the next higher 

rank, of which that unit is a part, may be noted. The name"in parentheses is in the recommended form noted for that name in its primary 

listing, even if that form is in brackets. Abbreviations used 

include:

FM formation

GP group

MBR member

SER series

CGL conglomerate

DOL dolomite

LS limestone

QTZ quartzite

SH shale

SS sandstone

STS siltstone

VOLCS volcanics

MTN has been used for Mountain where space is limited, 

are used for Saint and Sainte.

St. and Ste.

Usage. The primary purpose of this list is to aid U.S. Geological Survey authors in the preparation of their reports. All Survey 

reports that use geologic names are reviewed by the Geologic Names 

Committee for proper usage of names according to records on file. In 

this compilation, the usage approved for a geologic name is noted by 

a "U" in the usage column.

Lithology. Many names of geologic units (formation, member, 

bed, lentil, group, supergroup) do not refer to a lithology. The 

lithology field notes the dominant lithology(ies) for such named 

units. Lithology is omitted from this field if it is not in the 

first usage noted but is shown in a subsequent usage. The space is 

small, so most lithologic terras must be abbreviated. Many of the 

abbreviations used are fairly standard. A few abbreviations do not 

designate true lithologies but serve in lieu thereof. In addition to 

the abbreviations listed above under the heading "Geologic name," the 

following have been used:

NVC novaculite

OBS obsidian

OOL oolite

PCL pyroclastic rock

PHL phyllite

PHS phosphate

in rock description and identification. Abbreviations used in this 

field are as follows:

YL yellow

Thickness. Maximum thickness at the type locality is noted in 

meters, rounded to the nearest second significant figure; five is 

rounded even so that 135 and 145 both become 140. Many units are not 

fully defined at their type localities; where only general or regional thickness is available, that is recorded.

T.yoe locality. The type area/locality/section is identified as 

within one of nine geographical areas of a State; these areas are determined by dividing the maximum longitudinal and latitudinal dimensions of the State by three. The nine areas are designated by the 

abbreviations NE, NC, NW, WC, C, EC, SE, SC, and SW. A rectangular 

State so divided would have nine equal parts. Many irregularly 

shaped States do not have all nine areas represented. Names originating in Canada or Mexico and extended to the United States are 

identified by CAN or MEX.

Reference. A reference, noted by a letter, is included to help 

the reader learn more about the origin of the name and the characteristics of the unit it represents. Almost all the names noted have 

been described in one of the lexicons of geologic names of the United 

States that have been published as bulletins of the U.S. Geological 

Survey. The letters refer to these lexicons as follows:

A Bull. 896, Wilmarth, 1938

B Bull. 1056-A, Wilson and others, 1957

C Bull. 1200, Keroher and others, 1966

D Bull. 1350, Keroher, 1970

E Bull. 1520, Luttrell and others, 1981.

Most names described in A are also described in C; the reference chosen is usually the most definitive. Names in A or C are not repeated 

in B, D, or E.

Identifier. Computer search requires a unique identifier that 

can be used to isolate one record from all others. A four-letter
8 GEOLOGIC NAMES OF THE UNITED STATES THROUGH 1975

mnemonic derived from each geologic name and followed by a two-digit 

sequence number serves this purpose.

The mnemonic has been derived from the geographic part of the 

geologic name according to the "modified Franklin method" (American 

Association of Petroleum Geologists, Committee on Standard Stratigraphic Coding, 1967) by eliminating letters until only four remain. 

Elimination starts from the comma in the geologic name and proceeds 

to the left in the order noted below, but the first letter of each 

word is used regardless of its position in the elimination sequence.

1. A 8. Y 14. L 21. K

2. E 9. Doubles 15. D 22. B

3. I (delete one) 16. C 23. V

4. 0 10. T 17. M 24. X

5. U 11. N 18. F 25. J

6. W 12. S 19. G 26. Q

7. H 13. R 20. P 27. Z 

The mnemonic is always four letters long, including blanks at the end 

where a name is short. The original derivation was accomplished by 

means of the computer, and for this purpose a comma was inserted between the geographic part of the name and the rank or lithology. Insignificant English words (the, on) are omitted, but those of foreign 

derivation (such as La, 0*, De) are kept and treated as individual 

words. Mac and Me are combined with the second part of the name as 

one word, and the first letter of the second part is used in the mnemonic, so that McAfee is spelled MCAFEE and the mnemonic is MCAF.

Because the same mnemonic may be derived from different names, 

because the same name may be used for different rock units, and because the same rock unit may be represented many times (once for each 

usage and each age in each State), a two-digit sequence number has 

been added to complete the unique identifier. These six characters 

are recorded in the list for the benefit of a user who might wish to 

assemble a similar computer list or who might have access to this one 

on the computer and desire update information.

This method of identification is a modification of the one submitted by the Committee on Standard Stratigraphic Coding in that it 

derives every mnemonic strictly according to the rules noted. No 

modification is made when the same mnemonic represents different 

names; instead, a sequence number is added to differentiate between 

otherwise duplicate identifiers. No number is used in this list to 

identify rank or other definitive characteristics of a rock unit.

PROBLEMS AND DISCUSSION

Some geologic names are classified as informal by an author, 

even though he may define them just as carefully as he would a formal 

name. These names have been omitted from this list until they are 

given formal status. Many other names must be considered informal 

because of the ways they are introduced. These include names used 

only in charts, figures, map explanations, tables, and abstracts, or 

in text without any definition or description. If an author capitalizes some names (a practice recommended by the Code for formal names) 

but does not capitalize others, we assume that the uncapitalized 

names are informal and omit them. Where there is reasonable room for 

doubt as to formal intent, however, a name is likely to be included 

if it can meet the principal requisites for formal usage.
GEOLOGIC NAMES OF THE UNITED STATES THROUGH 1975 9

Names that have been abandoned and that have not been used subsequently are omitted, but most names that continue in use after 

someone abandons them are included. Names that have been long unused 

and that do not appear to serve a meaningful purpose are likely to be 

omitted, particularly if other names are in active use for the same 

rocks in that area. Morphologic, economic, paleontologic, time, tectonic, facies, and other terms that do not meet the requirements of 

rock-stratigraphic names are also omitted.

Group is defined in the Code (Art. 9) as "the rock-stratigraphic 

unit next higher in rank than a formation; a group consists of two or 

more associated formations," and (Art. 9, remark a) "A group consists 

wholly of divisions defined as formations," but an exception to the 

above seems also to be provided for: "In some reconnaissance work, 

the term 'group' has been applied to stratigraphic units that appear 

to be divisible into formations but have not yet been so divided." 

Does the exception really signify approval or does it merely cite an 

example of unfinished work that holds promise of division wholly into 

formations to provide a valid group?

The exception noted above creates problems, for an undivided 

group is not really a group of formations but simply a group of unnamed rock units. The formation is defined as the fundamental unit 

in rock-stratigraphic classification, but a group without formations 

lacks any fundamental units. Many rock units were called groups before the Code came into existence and therefore were not established 

under the umbrella of the exception, yet after many decades they remain undivided. Should they continue to be called groups?

Any rock unit called a group can also be called a formation, and 

in the absence of division of those rocks, that procedure would provide for a fundamental unit. This list was prepared on a State-byState basis, and the State lists were then combined. In order to 

identify those groups that have unnamed formations within them, or 

those groups that lack two or more formations within a State and so 

are not groups in reality, a slash has been inserted before the name 

and a record has been inserted in brackets, calling the unit a formation. These notations will alert a subsequent worker to take steps 

to clarify the problem.

Article 6 in the Code concerns names at formation rank, and remark J concerns "Complex. If a mass of rock is composed of diverse 

types of any class or classes or is characterized by highly complicated structure, the word 'complex' may be used as part of the formal 

name instead of a lithologic or rank term." The phrase "instead of" 

indicates that a lithologic term should not be used with the word 

"complex." Accordingly, where "complex" is used together with a 

lithologic term, the name has been preceded by a slash, and a usage 

without lithology has been added in brackets.

In the review process, wherein some usages of a name were selected for inclusion in this list and others were omitted, the emphasis 

in selection was accorded to State or Survey usage or to identification of a lithology if one seemed dominant. Where the member is of 

the same lithology as the formation, the lithology is omitted before 

the word "member" to save space and to avoid redundancy.
10 GEOLOGIC NAMES OF THE UNITED STATES THROUGH 1975

This list does not include reference to subgroup or megagroup 

names, for these terms are of very limited use. It also omits reference to sequence, cyclothem, or names for units of less than formation rank that are not part of a named formation.

Hyphenated names are usually derived by combining the geographic 

parts of two normal names. The hyphenated name does not reflect a 

geographic name, so it is invalid and is accordingly slashed.

The U.S. Geological Survey endeavors through the review process 

to assure that all usage of geologic names by Survey authors is accurate and timely. The files of Survey usage of names are built and 

updated primarily from manuscripts submitted for publication, but 

changes are also made when new reliable information is received from 

outside sources. Many rock units in this country have not been studied by Survey geologists and therefore are not indicated by a "U" in 

the usage column. Because other units have not been studied in recent decades, Survey files may not be up to date, though a concerted 

effort has been made in preparing this list to update these files 

where new data have demonstrated the need. Absence of a "U" in the 

usage column should not be construed as unacceptability of a name by 

the Survey only that the name in question has not yet been adopted 

for use by a Survey author.

Some names that have not been used by Survey authors in recent 

years are still shown in the Survey files in their old form and may 

now be out of date because of changes in the Code since their last 

Survey usage. If that usage is now in violation of the Code or 

otherwise is not in good form, the name is flagged by a slash, as is 

any other improper name, to alert the next Survey author to make the 

required changes. A suggested use that would correct the problem is 

shown in brackets. The fact that geologic names are not used everywhere at the same rank or lithology may lead to differences between 

Survey and State usage. For example, Survey usage may be at formation rank in one part of a State, and State usage may be at member or 

group rank in another part of the State.

A significant problem exists in use of the same name for different rock units (preemption, Art. 3 of the Code). In the Appalachian 

States, for example, the same name has been applied to several different rock units in sequence. Such usage is called "informal" in 

the Code (Art. 10 h). Though recent literature has corrected many of 

these multiple usages and so has reduced the problem, some of the repetitive names have continued in formal usage. Where the problem 

still exists and the names were established by the same author, the 

name of the unit stratigraphically lowest in the sequence is herein 

shown as acceptable because that unit would have been described first 

in the text; the other names are preceded by a slash. If the names 

were not described by the same author, the rule of priority (Art. 11 

of the Code) has been applied in determining which names to slash.

Many duplicate names have been applied to totally unrelated rock 

units. The rule of priority has been applied to these, also. An exception is allowed in the Code (Art. 11 c) for units whose "geographic and stratigraphic separation preclude confusion." Geographic 

separation was probably intended to refer to units in States far removed from each other and in different geologic provinces. In this 

list, the assumption is that at least the States should not be adjacent. Therefore, the more recent of two uses of the same name in the
GEOLOGIC NAMES OF THE UNITED STATES THROUGH 1975 11

same or adjacent States (adjacent is here determined by including all 

States in which the respective units are identified) is marked by a 

slash to denote preemption. To satisfy the spirit of the Code, the 

separation should be greater. For example, Delaware and Pennsylvania 

involve some markedly different geologic provinces but are adjacent, 

whereas Maryland and New Jersey have much similar geology in the same 

provinces but are not adjacent. Duplication in any areas so small 

should be avoided.

Coal beds have been included where it is clear that the State 

uses the name formally as a rock-stratigraphic name; otherwise they 

are omitted as economic (Art. 1 f). Oil sands are omitted unless 

they are clearly used as rock-stratigraphic names.

Names of intrusive rock bodies are not considered geologic names 

by the Code (Art. 10 i). By analogy, a lava flow is here considered 

a rock body, and usage of the word "flow" in a name is slashed; where 

the dominant lithology is known, the term for it is entered in brackets in place of the word "flow"; where lithology is not known, the 

term "lava" is used.

Most rock units occur beneath the surface somewhere. In general, their concealed distribution is not as well known as their surficial distribution, but in areas of much drilling for oil and gas, the 

opposite may be true. One of the weaknesses, perhaps the greatest, 

perceived in this list of names is inadequate representation of the 

subsurface distribution of named geologic units. This inadequacy is 

particularly true for those parts of the country where structures are 

very gentle and topographic relief is very low. In such areas, only 

a few formations may be identified at the surface though the column 

of sedimentary rocks is 5,000 to 10,000 m thick. The names of many 

subsurface units are based on additions supplied by State Geologists.

In the interests of brevity and usability, this list is necessarily selective; it would be impractical, cumbersome, and confusing 

to record every name usage. Some selections may not be the most appropriate, and future work will show need for other changes and additions. For future listings, we hope to pick up changes as they are 

reported in the literature, but we would much appreciate having our 

attention called to errors or other needed changes based on information already in the literature.

This list of geologic names is maintained in the computers of 

the U.S. Geological Survey at Reston, Va.; Denver, Colo.; and Menlo 

Park, Calif. It can be consulted by persons having access to the 

computer to obtain lists of names sorted from this list for special 

purposes, for example, the names of Lower Devonian rocks in the Appalachian States or of Miocene rocks in California.
