Abstract:

MRDS is a collection of reports describing metallic and nonmetallic mineral resources throughout the world. Included are deposit name, location, commodity, deposit description, geologic characteristics, production, reserves, resources, and references. It subsumes the original MRDS and MAS/MILS. MRDS is large, complex, and somewhat problematic. This service provides a subset of the database comprised of those data fields deemed most useful and which most frequently contain some information, but full reports of most records are available as well.

Current status: As of 2011, USGS has ceased systematic updates to MRDS, and is working to create a new database, focused primarily on the conterminous US. For locations outside the United States, MRDS remains the best collection of reports that USGS has available. For locations in Alaska, the Alaska Resource Data File remains the most coherent collection of such reports and is in continuing development.

Resource 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 having more information about more aspects of the resource, records graded D having only summary information about the resource. Records graded B and C are intermediate between these, and records graded E generally lack bibliographic references.
