III The Arizona portion of the Mineral Resource Data System (MRDS; formerly the Computerized Resource Information Bank, CRIB) file is now accessible to the public. currently comprises approximately 3,300 records which contain information on the location, geology, and production of metallic- and a few nonmetallic-mineral commodities in Arizona. These records are stored in a mainframe computer at the U.S. Geological Survey (USGS) in Reston, Va. The data are dynamic; new information is added as it becomes available, and existing records are corrected as errors are found. Public inquiries may be addressed to ,the Regional ;\1RDS Representative at the U.S. Geological Survey, 12201 Sunrise Valley Drive, Reston, VA 22092, or at the U.S. Geological Survey, 345 Middlefield Road, Menlo Park, CA 94025. Procedures for public access can be representatives.
Several methods of retrieval are available for MRDS records, including computer printouts of entire records or parts of records, and (or) map plots for selected areas. selective searches of the file so that the user can obtain the specific information required.
Arizona MRDS records provide a source of resource literature, private reports and files, and field examinations by the reporters. The information is nonproprietary.
Most of the Arizona MRDS records are for metallic-mineral commodities, although data are also included for uranium and asbestos, which are important fuel and nonmetallic-mineral commodities, respectively. construction materials such as sand and gravel, industrial minerals, geothermal resources, organic fuels, and coal, either because such materials are widespread and generally available, the information about these commodities is included in other data bases, or the commodity is not geologically or economically important in Arizona.

published comprehensive information about the molybdenum occurrences in Arizona, and much of the molybdenum information in the Arizona records was extracted from her compilation. Special thanks are due to Donald F. Huber of the USGS in Menlo Park, Calif., who coordinated the contracts with the ABGMT. Several geologists of the USGS made their field notes available for entry into the file; these geologists include Roger P. Ashley, Roger D. Dockter, Warren E. Yeend, William J. Keith, and Norman G. Banks. To these and others who provided data and assistance for the completion of the Arizona records, I am very grateful.
PURPOSE OF THE ARIZONA MRDS RECORDS
MRDS records in general and the Arizona MRDS records in particular are designed to be working reference sources for solving various administrative and geologic problems. The data can be used to assess known and potentially locatable mineral resources, to provide a first-time look at the mineral deposits within a new study area, and to serve as a research tool for compiling regional metallogenic data.
Arizona MRDS records complement other resource files containing data pertaining to organic fuels, water resources, geothermal resources, and coal resources, as described briefly by the Office of the Data Administrator (1983). economic factors of production of metallic- and nonmetallic-mineral com modi ties is stored in the Minerals Availability System (MAS) of the U.S. Bureau of Mines (197 4). which can be linked to records in :viAS are indicated in the file-link field of each MRDS record. information is available from the U.s. Bureau of Mines, Western Field Operations Center, E. 315 Mountgomery Avenue, Spokane, WA 99107.
The Arizona portion of the MRDS file currently contains 3,301 records similar to those listed in table 1, which shows one record with a large amount and one with a small amount of information to illustrate the range of information contained in each record, whereas most records lie somewhere between the two examples. information commodities present, its exploration history, the size and shape of the deposit, mining information, geologic data, and at least one reference (Keefer and Calkins, 1978). Generally, these references include one or two main published references to which the user can refer COMPLEMENTARY FILES

DESCRIPTION OF THE RECORDS
An individual record may contain about the deposit's location, the for additional information, although some of the records were generated solely from field notes or unpublished nonproprietary file data.
Locational information is stored in at least one of three universal-transverse-mercator (UTM) coordinates; and township, range, and section. could not be located to within a mile of their actual site are omitted from MRDS.
Much of the production data for Arizona is currently stored on magnetic tape and is not yet in a form compatible with MRDS. When transformation of these data to an MRDS-compatible format is complete, they will be entered into MRDS.
The Arizona portion of MRDS contains records on large operational mines, mined-out localities, small mines, prospects, and occurrences. Records for mines that have produced more than 100 tons of ore are fairly complete, whereas information about small mines, systematically included and reflects, in part, the amount of information about the commodity and (or) the objectives of the reporter.
The storage-and-retrieval system known as the General Information Processing System (GIPSY), which allows for the change of existing information, entering of new information, and deletion of old or incorrect information. It is also the means by which MRDS is accessed during a retrieval.
The data collected for the Arizona records came fro·n various sources within the USGS and the A>3G1VIT. literature, both old and recent. At the outset, skeletal records were constructed from U.S. Bureau of Mines card files and State commodity sheets for Arizona housed at the former Conservation Division of the USGS (now part of the U.S. Bureau of Land Management, but no longer a distinct organizational entity). These records were subsequently expanded into the current data set by updating the existing information and by adding records for mines not in the original list. Several M.S. and Ph.D. theses provided data on specific districts or mines. The ABGMT drew on their numerous files of notes and clippings and used information from MAS. Finally, several records were assembled from data collected by USGS geologists during the Resource and Land Information (RALI) program carried out in 1973-74; these records are concerned primarily with small unnamed prospects.
The Arizona records are a compilation of known information primarily based on a search of existing literature and unpublished files. Each record has been checked for location accuracy to within one mile of the reported location, although most location data are much more accurate. A designation of accuracy as "accurate" or "estimated" was recently instituted for MRDS records and all newer records include these designations. On older records, this information was filled in during a final check of the data. To locations ways:

compilation simultaneously and because of the changing standards of reporting over the many years during which these data were collected, earlier records varied widely and were inconsistent. Therefore, once· most of the records were stored in the computer, an effort was made to update the data to the current standards. Keypunching errors are also inevitable in a data base this large. To minimize such problems, several fields necessary. "accurate" or "estimated" to the locations in older records, the latitude and longitude of each record were checked to ensure that they fell within the quadrangle reported in the record. If they did not, the location (or on some records the quadrangle) was changed. The ABGMT recently redefined the mining districts in Arizona, so records with older district names have been changed to conform with these new names.
mineralogy and deposit type, may have the designation "unknown." This designation ordinarily means that the source documents did not provide this information and that the reporter was unable to extrapolate ·the information from nearby localities or to infer it from the geology of the area. Also, any of the required fields found blank at the final check of the record were given the designation "unknown" because insufficient time was available to check the geologic maps and literature for each deposit. Deposits with no entry for deposit name were designated "unnamed deposit." Deposits without a yes or no production designation were generally presumed not to have produced, on the basis of other information in the record; a few deposits were designated undetermined ("und"); and a few others indicated a small production.

These maps were compiled directly from the computer and have not been edited or reviewed for conformity with USGS standards and nomenclature. At the small scale of these maps, many points are not resolvable, but better resolution can be obtained by compiling at a larger scale.
