Service Description: This digest of the complex mineral resources database is intended for use as reference material supporting mineral resource and environmental assessments on local to regional scale worldwide. This service consists of a point feature layer showing the location of commodities, including a grade of the amount and diversity of data obtained for the location. It also includes three related tables: Names (alternative names of sites), Materials (minerals), and Commodity. The tables and the point feature layer can be related on the Record ID and DEP_ID fields, respectively. Learn more at https://mrdata.usgs.gov/mrds/ .

Description: The
Mineral Resource Data System (MRDS) is a collection of relatively old reports describing metallic and nonmetallic mineral resources throughout the world. Included are name of the occurrence, location, commodity, deposit description, geologic characteristics, production, reserves, resources, and references. It subsumes the original MRDS and MAS/MILS. While the database has fields for operational characteristics such as operating status, ownership, and production, those values are out of date. This service provides a subset (
see "compact" version in "Documentation" section) of the database comprised of those data fields deemed most useful and which most frequently contain some information. Full reports of most records are available @
https://mrdata.usgs.gov/mrds/.
Current status: As of 2011, USGS has ceased systematic updates to MRDS, and is working to create a new database (
USMIN Mineral Deposit Database), focused primarily on the conterminous U.S. For locations outside the United States, MRDS remains the best collection of reports that U.S. Geological Survey has available. For locations in Alaska, the
Alaska Resource Data File remains the most coherent collection of such reports and is in continuing development.
Occurrence descriptions here include an indication of the overall quantity and diversity of information they contain. Many records in this database are simple reports of commodity at some location, but some records provide substantial detail of the geological setting and industrial exploitation of the resource. To help users find these more thorough records, a map interface and search form are provided that
rank results by overall quality. Records graded A have more information about various aspects of the resource. Records graded D usually only contain scant information about the resource. Records graded B and C are intermediate between these. Records graded E generally lack bibliographic references.
Please refer to this
data dictionary for commodity codes found in the feature layer and commodity table.
Hundreds of people have contributed to the development of MRDS and MAS/MILS over several decades. The present digest owes much of its coherence to Bill Ferguson, Bruce Lipin, and Paul Schruben of the U.S. Geological Survey.
