DESCRIPTION OF INDIVIDUAL DATA ITEMS AND CODES IN CRIB

By Eleanor K. Keefer and James A. Calkins

ABSTRACT

The U.S. Geological Survey's Computerized Resources 

Information Bank (CRIB) is being made available for 

public use through the computer facilities of the University of Oklahoma and the General Electric Company, USA. The use of General Electric's worldwide 

information-services network provides access to the 

CRIB file to a worldwide clientele. This manual, which 

consists of two chapters, is intended as a guide to 

users who wish to interrogate the file. Chapter A contains a description of the CRIB file, information on 

the use of the GIPSY retrieval system, and a description of the General Electric Mark III Service. Chapter 

B contains a description of the individual data items in 

the CRIB record as well as code lists.

CRIB consists of a set of variable-length records on 

the metallic and nonmetallic mineral resources of the 

United States and other countries. At present, 31,645 

records in the master file are being made available. 

The record contains information on mineral deposits 

and mineral commodities. Some topics covered are: 

deposit name, location, commodity information, description of deposit, geology, production, reserves, potential resources, and references.

The data are processed by the GIPSY program, 

which maintains the data file and builds, updates, 

searches, and prints the records using simple yet versatile command statements. Searching and selecting 

records is accomplished by specifying the presence, 

absence, or content of any element of information in 

the record; these specifications can be logically linked 

to prepare sophisticated search strategies. Output is 

available in the form of the complete record, a listing 

of selected parts of the record, or fixed-field tabulations.

The General Electric Mark III Service is a computerized information services network operating internationally by land lines, satellites, and undersea 

cables. The service is available by local telephone to 

500 cities in North America, Western Europe, Australia, Southeast Asia, Japan, and Saudi Arabia. An 

interface called the "foreground driver" is used to link 

the GIPSY program to the General Electric system.

INTRODUCTION

The U.S. Geological Survey's (USGS) Computerized Resources Information Bank (CRIB) 

is being made available for public use through 

the computer facilities of the University of 

Oklahoma and the General Electric Company 

MARK III Service. 1 This chapter contains a 

description of the individual data or information items 2 in the CRIB record, an index list 

of the data items, and a set of code lists. The 

information in Chapter B will be of assistance 

in understanding the file content and in formulating useful retrievals. Although approximately 400 data items are available, one record 

is unlikely ever to contain information on all 

these data items.

A data item is the smallest unit of information to which reference is made in a record. A 

data item consists of one or more of the following four main components: (1) Label, (2) 

item (label) description, (3) field (associated 

with the label), and (4) data (contained in the 

field).

The minimum requirement for defining a 

data item is a label. The label as used in the 

GIPSY program is a unique alphanumeric identifier of 1-7 characters. All data items in the 

CRIB record are defined in terms of a label, 

and the collection of all labels in the record 

constitutes the data dictionary or search dictionary. The label can be thought of loosely as 

the name of a field of a given data item, and

1 MARK III is a registered service mark of General Electric 

Company, USA.

- "Data" and "information" are synonyms in most of their 

senses and are used interchangeably in this manual. In the str.ict 

sense, the term "data" constitutes facts and figures (as the number 

"15"), and when meaning is assigned to this number, it becomes 

information (15 tons). Implicit in a set of numbers or letters 

(data) is meaning; therefore, "data" implies information, and so 

the two words are synonyms.

Bl
it serves to identfy each field or data item to 

the user and to the GIPSY prog-ram. For example, the label A10 defines the field containing 

the DEPOSIT NAME. The label is the basis 

for identifying fields to be searched during a 

retrieval.

The item description is an optional descriptor 

associated with a given label. It consists of 

1-59 characters and serves to describe the data 

item in readable English on the printout or to 

perform the function of a header line. For example, the label A10 has the item description 

DEPOSIT NAME associated wtih it, and the 

label Al generates the header line NAME AND 

LOCATION.

The field is the computer storage space made 

available to store data. All fields are taken as 

variable-length fields by the GIPSY program. 

However, these variable-length fields can be 

rigidly formatted by controlling the length and 

nature of the data entered into the fields; thus, 

many fields in the CRIB record are equivalent 

to fixed-length fields.

The data is the alphanumeric entry placed in 

the field. It may consist of text, a number, a 

code, or keywords.

INDIVIDUAL DATA ITEMS

This section contains a detailed description of 

each data item. The data items are arranged 

label by label in the order in which they are 

printed in the standard output record (see 

dummy record, fig. 1). The material includes 

the label, item description, format (if any) of 

data contained in the field, what the data mean, 

how the field is used, and other information. 

Following the descriptions of many labels is a 

code letter, or letters, indicating one or more 

key characteristics of that label, of the item 

description, of the field, or of the data contained in the field. The meaning of these codes 

is as follows:

L ____Item (label) description only appears in 

output record. No entry is associated 

with the labels and the item description itself constitutes the data. Data 

items of this type are treated as literals (see Chapter A, p. A8) when 

used in the COPY, SORT, or COUNT 

commands.

N __ __Numeric field or alphanumeric field 

treated as a numeric field.

F __.Formatted field.

PF _Partially formatted field or field containing key words or codes of varying 

lengths.

D ---.Discontinued label. Entries may appear 

on early records, but the label is no 

longer in use for current input.

NS ___Label not on standard input form 

10(9-76).

C __A coded field. Entries are coded from 

code list indicated.

RECORD IDENTIFICATION

BIO Record number. The record number is a 

unique identifying code assigned to each 

record in the file; it is alphanumeric and 

usually contains seven characters. (F).

Record type. 

A. Form A used as source document. 

(NS, L, D).

B. Form B used as source document. 

(NS, L, D).

D. Special-purpose form used as source 

document. (NS, L, D).

U. Record that has been updated. Updating 

can include significant or material additions, deletions, or other changes to 

the original data in one or more fields of 

the record. It does not include simple 

spelling or other minor typographical

alphabetic characters see CRIB Country 

Code List (List C, p. B23-B25). (C, F).

A50 State code. State, Province, or other 

second-order political subdivision below the 

country level. States in the United States and

Area Codes of the U.S. (List J, p. B28 and 

fig. 4). The numeric code for a drainage area 

is entered in the first two spaces in the field. 

The rest of the entry is used to describe the 

drainage area further (For example, the code 

02 indicates the Middle Atlantic region, and 

"Upper Hudson River" indicates the specific 

drainage area.) or to enter information 

about the drainage area of a non-U.S. mineral deposit. (PF, C).

A63 Physiographic province. The physiographic province in which the deposit is 

located. See Physiographic Provinces Codes 

of the U.S. (List K, p. B30 and fig. 5). The 

numeric code for a U.S. physiographic province is entered in the first two spaces in the 

field. »The rest of the entry is used to describe the physiographic province further 

(for example, Southern Catskills) or to describe the province of a non-U.S. deposit. 

(PF, C).

A64 Land classification. A two-digit coded 

field classifying the land in terms of privateland ownership and various types of public 

lands see Land Classification Codes (List

B8
P, p. B30). This is n recently added field and 

as yet contains little data. (C, F).

A100 Quadrangle scale. Under quadrangle 

scale is entered the denominator of the fractional scale of the map of the quadrangle 

where the deposit is located (For example, 

if the scale is 1:24,000, then the entry is 

24000). (N, F).

Format:

quadrangle is reported. (NS).

Location methods. Four possible location 

methods available are: geodetic coordinates, 

Universal Transverse Mercator coordinates, 

State Grid coordinates, and the public-land 

survey (township range section) system. 

In addition, an X-Y cartesian coordinate system is available for special-purpose use. Usuually just one of these methods is used by a 

reporter, but in some records, two methods 

(such as, latitude and longitude and also 

township, range, and section) may be used.

Geodetic coordinates. For the two fields A70 

Latitude and A80 Longitude please note 

that when an exact location is not available, 

reporters have used an arbitrary center point 

or the coordinates of a principal mine or 

quarry. Even though a single-point location 

may not be a realistic "center," nevertheless, 

an arbitrary location is important so that the 

area in question can be retrieved on the basis 

of latitude and longitude.

For an example of a retrieval based upon 

latitude and longitude see chapter A, fig. 7, 

of this report.

107 Altitude (N, PF).

Usual format: 9999 FT

This is the surface elevation of the item 

being1 described (mine, prospect, or district). For a large area, the altitude of a 

point, or an average altitude is reported. 

The usual format is digits followed by a 

space, then FT or M (feet or meters).

The Universal Transverse Mercator grid 

is shown on all USGS quadrangle maps 

printed since 1956. To define a point in 

the UTM system, a northing, easting, and 

zone number are required. The world is 

divided into 60 meridional zones numbered 

from 1 to 60; each zone covers a strip 6° 

wide in longitude.

Zones north of the equator are positive 

(+) ; zones south of the equator are negative (-). The zone number is indicated in 

the lower left corner of 7^-minute topographic sheets. Within each zone coordinates are measured in meters north of the 

equator and east of the west boundary of 

the zone. Grid lines drawn on the base 

map, together with a metric coordinate 

reader, make it possible to plot a point in 

the UTM system.

Each state has its own coordinate system, 

and these can be used as location coordinates. State coordinate ticks are printed 

on the edges of most topographic maps. 

Detailed descriptions of the State coordinate systems can be obtained from the appropriate State agencies. A listing of the 

the four-digit zone numbers for each State 

can be found in "Program Description, 

D0154" (Buehrer, 1969, unpub. data), 

available from the U.S. Geological Survey 

Computer Center, 801 National Center, 

Reston, Va. 22092.

Map X-Y coordinates

An example of an X-Y coordinate system 

is that used in many records on Alaska, in 

which each mineral location is referenced

in X-Y on 1:250,000-seale maps and also 

on 1:63,360-scale maps when available. 

This location system may in the future 

come into wider use, especially in locating 

drillholes.

A77 Township(s). Space is provided for 

two townships on the standard form. Three 

spaces are allotted for digits, followed by 

a space for N (north) or S (south) in 

each. (F).

This can include the direction and distance of the location from some nearby 

town or prominent geographic feature or 

other pertinent information. 

On some records in the CRIB file, this field 

is used to indicate the position within the 

section (that is, the quarter section).

B26-B28). Element codes are the standard 

chemical symbols of one or two letters. Other 

commodities are coded in three letters or 

three letters and a number. (F, C).

Significance. This section classifies the commodities shown in CIO into major or minor 

products, coproducts, byproducts, potential 

products, and occurrences. Codes used in 

these six fields and method of entry are the 

same as in CIO. In many records, the reporters have entered commodities in the CIO 

field without breaking them down into their 

significance here.

MAJOR Major product (F, C).

MINOR Minor product (F, C).

Four subfields of four spaces each are allowed 

for each of the above two fields.

COPROD Coproduct (F, C).

BYPROD Byproduct (F, C).

OCCUR Occurrence (F, C).

Three subfields of four spaces each are allowed for each of the above four fields.

C20 Commodity specialist information. Commodity codes from List E (p. B26-B28) 

will be entered here (in the same format as 

in CIO) when the following conditions apply: 

(1) The reporter is a commodity specialist 

and is supplying information oh his own 

commodity, or (2) information is obtained 

from sources that were originally compiled 

by a commodity specialist. Four subfields of 

four spaces each are allowed for C20.

C21 Special field 1 (NS).

C22 Special field 2 (NS).

C23 Special field 3 (NS).

The above three fields are used by commodity 

specialists for special information not entered into other fields.

C30 Ore materials (minerals, rocks, and so on). 

This field is for the names of the most important ore minerals, rocks, or other ore 

materials.

C41 Commodity subtypes or use categories. 

This field provides for the subdivision of commodities into specialized subtypes, if needed, 

or into categories based upon end use. 

Example: Bauxite coded AL1 in CIO, could 

be further classified as:

fields relating to the economics of a mining 

operation. These include (in the millions of 

dollars) : the costs for exploration, development, and expansion of the mining operation; 

the cost of the mill; the total investment; and 

the mill capacity (in tons or other units). A 

field also is available for general economic comments. These fields are listed below:

C42A Exploration M$ (N). 

C42B Development M$ (N). 

C42C Expansion M$ (N). 

C42D Mill M$ (N). 

C42E Total investments M$ (N).

C42F Mill capacity per year. In thousands of 

metric tons (or other units) per year. 

(N, PF).

C42G Year applicable.

C42 Economic comments. This field is used for 

any comments relating to economic factors 

that might govern or affect the exploration 

of the deposit or commodity. These could include such items as distance to market, railroad, or road; high altitude; labor or price 

situation; favorable or unfavorable mining 

conditions; or unusual milling problems.

EXPLORATION AND DEVELOPMENT

A20 Status of exploration or development. 

This field shows the degree of development of 

the deposit into four categories in terms of 

the surface and underground information 

available. It will be coded by one of the number codes from Status of Exploration or Development (List B, p. B22). (C).

A21 Property is active. This entry is intended 

to indicate whether there was any activity at 

the time the record was reported. It is applicable mainly to specific tangible localities 

(such as prospects, mines, or districts). Activity includes production or any present-day 

exploration or development work. (L).

A22 Property is inactive. Indicates that the 

property was inactive at the time the record 

was reported. (L).

LlO Year of discovery. The year or approximate year of discovery is entered here. In 

some records, generalized entries such as 

PREHISTORIC, PRESPANISH, OR REVOLUTIONARY WAR may have been used 

here

L20 By whom. Name of company, organization, or person most closely involved in the 

discovery.

L30 Nature of discovery. Codes of one letter 

each are used here to describe the nature of 

discovery. (See Nature of Discovery, List L, 

p. B30). If the letter F is used indicating 

"other," this may be clarified under the comments field L110.

L40 Year of first production. This field indicates the year or approximate year of first 

production. The same kind of entries are used 

here as in LlO above.

A12 Present or last owner. The name of the 

person or organization that owns or recently 

has owned the mineral rights to the deposit.

A13 Present or last operator. The name of 

the person or mining company that is actually working the deposit or that most recently worked it, if it is now inactive. If the 

operator is the same as the owner, this name 

should appear in both A12 and A13.

WORK DONE BY USGS

Three lines, each constituting a single field, 

are available in this table allowing for the accommodation of the following three subfields:

B12
Year. The year the work was done or started.

Format: 1191715

Type of work. Codes are used here from Type 

of Work Done (List M, p. B30). If OTHER 

is entered, it may be clarified in comments 

field LI 10. Seven spaces are allowed here.

Format: X X X X X X X

Geologist and results. Name of geologist within the USGS and the results of his (her) 

work.

L41 (1st line of table) (C, PF, N). 

L42 (2nd line of table) (C, PF, N). 

L43 (3rd line of table) (C, PF, N).

WORK DONE BY OTHER ORGANIZATIONS

Five lines, each constituting a single field, 

are available in this table allowing for the accommodation of the following subfields: 

Year. The year the work was done or started.

Format: 1975

Type of work. Codes are used here from Type 

of Work Done (List M, p. B30). If OTHER 

is entered here, it may be clarified in the 

field LI 10.

L80 (4th line of table) (PF, NS, C, N).

L90 (5th line of table) (PF, NS, C, N).

Ll00 Reports available. This field is for citing 

available reports, either published or unpublished, that deal with the exploration and 

development of the deposit.

LllO Exploration and development comments. 

Comments on exploration and development, if necessary to clarify the above entries in this section.

DESCRIPTION OF DEPOSIT

C40 Deposit types. Examples of entries in 

this field are given in Deposit Types (List F, 

p. B28). This list is not exhaustive, and other 

deposit types may have been used. (PF).

M10 Form/shape of deposit. Entries from

Form/Shape of Deposit (List N, p. B30)

are commonly found in this field. This list is

not exhaustive, and other descriptive terms

may be used. (PF, C). 

Size/directional data

M15 Size of deposit. The general size of the 

deposit will commonly be indicated by one 

of the key words: LARGE, MEDIUM, or 

SMALL. In some records the actual size is 

entered (in acres, sq km). Size, following 

the scheme devised for the metallogenic 

map of North America (Guild, 1968), relates to the amount of metal or mineral 

contained in the deposit, district, or area 

being described. This scheme, which shows 

the most common metals, is shown in 

figure 2. The key words represent different 

value ranges for the different commodities. 

For example, an iron mine containing 

about 150 million tons of iron would probably be considered a LARGE mine, whereas a LARGE gold mine would contain only 

about 500 tons of gold. (PF).

Abbreviations for units. In the following 

pages, certain fields are units fields associated with numeric entries. The abbreviations of these units are shown in 

Measurement Units (List H, p. B28). In 

the numeric fields, the figures given may 

represent only rough averages. These 

fields, although not formally defined as to 

field length, are nevertheless formatted 

fields because the data automatically start 

in position one.

M20 Depth to top (numeric field. Distance 

from the surface to the highest point of 

the deposit. (N, F).

M21 (units associated with M20) (C, PF).

M30 Depth to bottom (numeric field). Distance from the surface to the lowest point 

of the deposit. (N, F).

M31 (units associated with M30) (C, PF).

M40 Maximum length (numeric field). 

Overall length of the deposit, measured in 

the horizontal plane. (N, F).

M41 (units associated with M40) (C, PF).

y Suggested limits, subject to revision; blanks await study and advice from 

specialists. Categories principally for "spot" deposits in which commodity is 

the principal value contained; co-product values generally totaled, by-product 

values ignored. Extensive (usually bedded) deposits--e.g., NaCl, iron-formation, 

phosphates, gypsum-anhydrite, etc., probably not suited for meaningful size 

categorization on the map.

PRODUCTION

PROD Production. This label is used to indicate that there is an entry in one or more of 

the production tables or that one or more of 

the following labels have been used: YES, 

NO, LGE, MED, SML, D8, D9, DIG. It also 

generates the header line for the Production 

section. (L).

YES. Yes. Ore or any of the commodities 

listed are being or have been produced. (L).

NO No Production. No production present or 

past has occurred as of the date reported. 

(L).

LGE Large production (L).

MED Medium production (L).

SML Small production. The reporter uses his 

own judgment in describing production as 

large, medium, or small. (L).

ANNUAL PRODUCTION (ORE AND COMMODITIES)

Seven lines (numbered 1-7) are provided in 

this table for annual production information 

for ore and for as many as six commodities; 

one line is available for each item reported. The 

lines are formatted as follows:

thousand units

year grade or use

D1-D7 Item and accuracy. Commodity codes 

from Commodity Codes (List E, p. B26-B28) 

are entered in the first four spaces. The last 

three spaces are intended to provide an indication of whether the production figures 

are accurate, estimated, or an average. If 

figures are not available, the reporter should 

indicate whether amounts are small, medium, 

large. See Accuracy (List G, p. B28) for 

these codes. (F, C).

B15
D1A-D7A Amount (numeric field.) Production figures are reported in thousands of 

units. Therefore, the figure given must be 

multiplied by 1,000 to obtain the production 

figures in single units. (F, N).

Format:

Example: 0004.253 on printout would represent 4253 as an actual figure in 

single units.

D1B-D7B Thousand units. These fields contain the units associated with the amount 

field. The reporter may have repeated the 

same commodity but with different production figures and different units on another 

line of the table. Units should be abbreviated 

as shown in Measurement Units (List H, 

p. B28). In rare records, figures greater than 

99,999,999,000 may be entered. Then, millions 

of units will be entered in the "thousand 

units" field. (F, C).

Example: 

D1A

(amount) 

00000234

(thousand units) 

DIB MIL TONS

would represent 234 thousand million tons or 

234,000,000,000 tons.

D1C-D7C Year. These fields of four spaces 

each contain the year of production, if 

known. On earlier versions of the CRIB input forms, the production years were entered 

in a field, D8, called "Production Years." 

This field is no longer used, and the entries 

have been moved into their proper places in 

various production tables. However, some 

records may still contain production years in 

field D8 instead of in fields D1C-D7C. 

(F,N).

D1D-D7D Grade or use. An unformatted field 

containing the grade of the item. Some records may show a particular end use. Grade 

refers primarily to ore grade and should 

include the grade of the different metals in 

the ore.

Example: D1D<11.5 % PB; 250 OZ/TON 

AG; 5 </c CU; 0.1 </c AU; ZN 

UNKNOWN>

Where the specific grade of the ore is unknown, the reporters have been asked to list 

the principal commodities (metals) in the 

ore.

CUMULATIVE PRODUCTION 

(ORE, COMMOD., CONC., OVERBUR.)

Nine lines (numbered 8-16) are provided in 

this table for information on cumulative production of ore and commodities and concentrates, and on overburden removed. This table 

may show a total cumulative production, production during a given time segment of two or 

more years, or intermittent production across 

several time segments.

The same general format is used here as in 

the previous table for Annual Production, except that a range of years may appear in fields 

G7C-G15C to indicate the range of years used 

for the cumulative production figures.

G7-G15 Item and accuracy. Similar to entries 

under D1-D7 (see p. B15). (F, C).

G7A-G15A Amount (numeric field) (8spaces). 

 Cumulative production figures are reported 

here in thousands of units. (See example 

under D1A-D7A on p. B16). (F, N).

G7B-G15B Thousand units. These fields define 

the units associated wtih the amounts column. 

(See example and explanation under D1BD7Bonp. B16). (F, C).

G7C-G15C Years. These fields contain the 

range of years of the cumulative production. 

(F,N).

G7D-G15D Grade or use. The grade or use, 

if kiiown. In the records of overburden removed, grade, or use does not apply. The 

grade is taken as the average across the 

span of years shown (see example under 

D1D-D7D, p. B16).

ANNUAL PRODUCTION 

(OVERBURDEN AND CONCENTRATES)

Seven lines (numbered 17-23) are provided 

in this table for information on annual production of concentrates and annual removal of 

overburden. This table is similar to the Annual 

Production (ore and commodities) table except 

that nine spaces are allowed in the "item" field 

instead of four.

P1-P7 Item and accuracy. Similar to entries 

under D1-D7 (see p. B15), except that the 

codes used will be OVB (overburden) or CON 

(concentrates). (F, C).

P1A-P7A Amount (numeric field). Annual 

figures for production of concentrates and removal of overburden are reported here in

B16
thousands of units. (See example under 

D1A-D7A on p. B16). (F, N).

P1B-P7B Thousand units. These fields contain the kind of units associated with the 

amounts column. (See examples and explanation under D1B-D7B on p. B16). (F, C).

P1C-P7C Year. These fields contain the year 

of production of concentrates or removal of 

overburden. (F, N).

P1D-P7D Grade, remarks. The grade of the 

concentrates. Grade does not apply to overburden. Some records may contain short remarks.

The following three fields (D8, D9, D10) may 

refer to items in any of the three production 

tables.

D8 Production years. This field is discontinued. However, entries in this field are on 

older records. Production years are now being entered in D1C-D7C, G7C-G15C, P1CP7C.

D9 Source of information. This field is for 

notations on the source (s) of the information in the production tables. In many records, the complete reference (s) appear under 

General References (labels F1-F4) in the 

same record. If item numbers appear here, 

they refer to the individually numbered lines 

of the production tables.

DlO Production comments. Explanatory notes 

that clarify or add information to the entries 

in the production tables. Item numbers may 

be used here also.

MINERAL RESERVES AND RESOURCES

The classification of mineral resources used 

in the CRIB file follows closely that devised by 

McKelvey (1972). Several refinements have 

since been published (Brobst and Pratt, 1973; 

U.S. Geological Survey, 1975; U.S. Bureau of 

Mines and U.S. Geological Survey, 1976), but 

these have not changed the basic classification. 

The only modifications made in the CRIB file 

to McKelvey's original scheme are the substitution of "Measured," "Indicated," and "Inferred" reserves for the terms "Proved," "Probable," and "Possible" reserves. The basic elements of this slightly modified classification are 

shown in figure 3.

Three tables plus certain additional fields are i 

used to computerize the information on the i

Identified

Measured Indicated Inferred

Reserves

Undiscovered

Potential resources

FIGURE 3. Diagram showing the classification of reserves and resources as used in the CRIB file.

resources of a given mineral deposit. Information in the table RESERVES AND POTENTIAL RESOURCES represents the total current resources of the deposit, that is, the entire 

area of the box shown in figure 3. The table 

RESERVES ONLY represents the area of the 

upper left corner of the box, and the table POTENTIAL RESOURCES represents the remaining area of the box, that is, those marginal 

and undiscovered resources that are not classified as reserves. Detailed discussion of the concept of mineral reserves and resources and of 

the classification of mineral resources is found 

in Brobst and Pratt (1973) and U.S. Bureau of 

Mines and U.S. Geological Survey (1976).

The tables RESERVES ONLY and POTENTIAL RESOURCES provide for a separation 

of reserve data from data on potential resources. Separate treatment of these two aspects of mineral resources represent an important objective of any mineral resources appraisal 

or inventory. Such information, however, is not 

always available.

RESERVES AND POTENTIAL RESOURCES

Six lines (numbered 1-6) are provided in 

this table for information on reserves plus potential resources of the given ore deposit or 

mineral locality. One line is used for each item 

reported. The fields in each line are similar to 

those previously described in the production 

tables. These fields are listed below: 

E1-E6 Item and accuracy (F, C). 

E1A-E6A Amount (numeric field) (F, N).

B17
E1B-E6B Thousand units (F, C).

E1C-E6C Year of estimate (F, N).

E1D-E6D Grade or use

E7 Source of information. Short notations on 

source of information about the reserves and 

potential resources. A more complete reference might be found under General References (labels F1-F4) in the same record.

E8 Comments. Explanatory notes are entered 

here, in particular, notes on the general outlook for finding more ore or developing the 

ore already there. In some records, the key 

words, "STUDY NEEDED," may be entered 

here to indicate that the reporter believes 

that the locality may have definite potential, 

warranting additional study of the locality.

RESERVES ONLY

Six lines (numbered 1-6) are provided in 

this table for information on reserves only, 

one line for each item reported.

Reserves may be treated as a single undedefined class in the table, or they may be 

divided into measured, indicated, and inferred 

reserves. If the latter is done, the class of reserves will appear in the "Grade or use" fields. 

The following entries are similar to these in 

the previously described tables. 

H1-H6 Item and accuracy (F, C). 

H1A-H6A Amount (numeric field) (F, N). 

H1B-H6B Thousand units (F, C).

POTENTIAL RESOURCES 

(EXCLUSIVE OF RESERVES)

Six lines (numbered 1-6) are provided in 

this table for information on potential resources, one line for each item reported. "Potential resources" refers to undiscovered deposits 

or to those identified reserves that at present 

are not recoverable. The following entries are 

similar to .those in the previously described 

tables.

GEOLOGY AND MINERALOGY

The entries on geology and mineralogy are 

those likely to bear some geological relationship 

to mineral deposits. Several entries (Kl, K2, 

K3, N30, N35, N40, N45, N50, N55, N60, N65) 

have a 10-space subfield for geologic ages allotted at the beginning of the entry. The codes 

for these ages will be found in Authorized 

Age Abbreviations (List 0, p. B30). On early 

records, however, the geologic ages were placed 

as complete words at the end of the entry.

K7 General geological environment. A specialpurpose field used only in records obtained 

from a tape file on metallogenic map data on 

North America. (NS).

Kl Age/names of host rocks The geologic 

ages and the rock types associated with the 

ore are entered here. (PF. C).

K2 Age names of associated igneous rocks. 

Ages and names of igneous rocks associated 

with the deposit. If the host rock itself is 

igneous, this field may show the same information as is in Kl.

K3 Age of mineralization. The geologic age 

during which the mineralization took place. 

(F, C).

K4 Pertinent mineralogy. This field provides 

for the entry of mineralogic information on 

minerals other than ore minerals.

K5 Important ore control or locus. One or 

more general or specific ore controls may be 

recorded here.

K6 Geological descriptive notes. Discontinued 

field used on early records for comments on 

the geology and mineralogy section. On later 

records, these comments appear in the comments field N85. (D, NS).

GEOLOGY (SUPPLEMENTARY INFORMATION)

REGIONAL GEOLOGY

N5 Major regional structures. This field may 

include a description of any significant large 

folds, faults, or other regional structures or 

trends.

B18
N10 Regional trends. Discontinued field used 

on early records. Now combined with N5 

(Major Regional Structures). (D, NS).

N15 Tectonic setting. Shield, geosyncline, 

platform, piedmont, or descriptive terms of 

other large-scale tectonic features may be 

entered here.

N20 Major lithologic/stratigraphic units. Discontinued field. Entries may appear in early 

records, but the label is no longer in use. 

(D, NS).

N25 Comments. Discontinued field. Entries 

may appear in early records, but now comments are entered in N85.

LOCAL GEOLOGY

Age /names of formations or rock types

N30, N35, N40, N45. Each of the four lines 

provided here has space for recording the 

ages and names of formations and rock 

types. Ages, coded from Authorized Age 

Abbreviations (List O, p. B30), should 

appear as the first subfield of each line. In 

older records, however, the geologic ages 

were placed at the end of each line. 

(PF, C).

Age /names of igneous units or rock types 

N50, N55, N60, N£5. Each of the four lines 

provided here has space for the ages and 

names of igneous units or rock types. The 

placement of the geologic ages is the same 

as in the previous four fields. (PF, C).

N70 Significant local structures. This field 

is for the description of any significant 

local structures that characterize the area.

N75 Significant alteration. Descriptive text 

on alteration may appear here if alteration has a bearing on the given deposit.

N80 Geological processes of concentration or 

enrichment. Additional information may 

be entered here on the basic causes of concentration or enrichment of the given deposit.

COMMENTS (GEOLOGY AND MINERALOGY)

N85 Comments (geology and mineralogy). 

Any information concerning the geology and 

mineralogy that has not been previously 

shown may appear in this field.

GENERAL COMMENTS

GEN General comments. This field is for any 

kind of general information about the deposit that has not been placed in other fields 

or that could be an elaboration on another 

field.

GENERAL REFERENCES

Fl, F2, F3, F4 (4 fields). These four fields 

contain bibliographic references. Reporters 

are encouraged to follow the standard U.S. 

Geological Survey arrangement (author's 

last name, author's initials, date of publication, title of article, name of periodical). 

However, this arrangement has not always 

been followed. Therefore references appear 

in a variety of ways. More than one reference may be stored under each label; this has 

been done in some records, usually under 

label F4.

INDEX LIST OF DATA ITEMS

This section consists of an index list of labels 

(fields) arranged in label sequence for quick 

reference. Each entry contains the label, item 

description, and the "characteristics codes" as

GLOSSARY

Alpha-numeric information (alphanumeric, alphameric) Information consisting of any 

combination of digits (0-9), letters (A-Z), 

and special characters (such as /, $, or ?,).

Assumed decimal point (implied decimal point) 

 A decimal point the position of which is 

known, but which is not physically entered 

(punched) into a numeric field.

Batch processing The sequential processing of 

records as a group (batch), one group at 

a time. Batch processing is in contrast to 

on-line processing, during which each unit 

of data is processed immediately at the 

time of presentation as in the airline 

reservation system.

Baud The speed of data transmission in bits 

per second.

Command procedure A user-oriented program 

composed of a prearranged set of operations steps and driven by user-controlled 

command words, specifications, and options.

Conversational (interactive) mode The user is 

communicating with the computer system 

in a "conversational" manner from a terminal by sending commands to the system. 

The system executes the commands and 

sends the reply back to the terminal. One 

type of on-line processing.

Data item (data element, information item, 

field) The smallest unit of information to 

which reference is made; for example, 

"country," "State." A set of related data 

items constitutes a record.

Direct access The process of finding information in storage, where the time required is 

independent of the location of other information in storage. A disk is a direct-access 

device. This is in contrast to the sequential access of tapes.

Disk (disk pack) A storage device consisting 

of a circular metal plate that has magnetic 

material on both sides and that is mounted 

on a rotating shaft. Read-write heads service both sides of the disk. Ten stacked disks 

constitute a disk pack.

Field (data item, information item) A specified category of data treated as a whole. 

The basic unit of a record.

File A collection of related records as a unit; 

for example, the records file and dictionary 

file of CRIB. Also, in the general sense, a 

collection of related files; for example, the 

CRIB file.

File maintenance Modification of file content; 

for example, insertions, deletions, transfers, and corrections.

B31
Fixed-fields (fixed-length fields) An arrangement in which the fields in a record are 

set beforehand to a specified length.

Fixed-length records Records of predefined 

length. Loosely used to mean that both 

record length and field length are set beforehand to specified length.

Floating decimal A decimal point without a 

predetermined fixed position within a numeric field. In a six-position number field, 

for example, the decimal may be in any 

of the six positions, depending upon the 

size of the number.

Foreground Interactive (conversational, online) mode of operation in which the user 

is communicating directly with the computer.

Foreground driver The command procedure 

program forming the interface between 

the GIPSY program and the General Electric Mark III System.

Format A predefined arrangement of characters, fields, print lines, and so forth. The 

term, "arrangement," is never used in 

computer work.

Interface A program or device that translates 

an initial program or signal into a form 

compatible with the next program or device.

Job Control Language (JCL) The language 

used to supply the necessary information 

to the computer system so that it can run 

your job. Includes such items as the name 

and address of the data file to be processed, the name of the program to be executed, what to do with the results, and so 

forth.

Label As used in GIPSY, a set of one to seven 

alphanumeric characters used to identify 

a data item or field to the GIPSY program.

Literal In the GIPSY system, a set of characters inserted into the output record of 

the COPY command.

Parameter statements (search variables) A 

list of the data elements the computer is 

to search for during a retrieval.

Program A set of instructions that tells the 

computer how to solve a problem.

Retrieval operation The actions connected 

with the recovery of information stored in 

a computer storage device.

RPG (report program generator) An IBM

program language that provides a convenient programing method for producing reports, performing calculations, and manipulating data.

Software Programs that help run the different 

components of a computer center and help 

the user to communicate with the computer.

Spanned record A record that overflows from 

the end of Tone track on a disk to the beginning of the next track.

Subroutine A program that is linked to a 

larger program and that performs a single 

task whenever the main program calls 

upon it to do so.

Track address A number identifying the location where information is stored on disk.

Utility programs Programs used to perform 

certain standard functions, called housekeeping functions; for example, update, 

transfer data from one device to another, 

sort programs, and so forth.

Variable fields (variable-length fields) Fields 

having no predefined lengths.

Variable-length records (variable-length format) A field or record of no predefined 

length.
