Mineral Resources On-Line Spatial Data

Mineral Resources Data System (MRDS)

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.
