The Critical Minerals in Archived Mine Samples Database (CMDB) contains chemistry and geologic information for historic ore and ore-related rock samples from mineral deposits in the United States. In addition, the database contains samples from archetypal deposits from 27 other countries in North America, South America, Asia, Africa and Europe. Samples were obtained from archived ore collections under the U.S. Geological Survey's project titled "Quick Assessment of Rare and Critical Metals in Ore Deposits: A National Assessment" (2008 to 2013) in an effort to begin an assessment of the Nations' previously mined ore deposits for critical minerals. Mineralized and altered rock samples were provided by the Colorado...

The "Li_Triangle_ARG_MRP_NMIC.gdb" geospatial database was developed by the U.S. Geological Survey for use in a geographic information system (GIS) to support mineral resource research and assessment of lithium resources in the Argentina portion of the central South American Lithium Triangle. The Lithium Triangle is host to significant amounts (nearly 60%) of the worlds known (identified) resources of lithium. Over 100 salars and lagunas, ranging in area from a few square kilometers (km2) to approximately 9,000 km2, are found within this region. The Lithium Triangle is approximately 400,000 km2 and encompasses about 150 internal drainage basins in northwestern Argentina, western Bolivia, northern Chile, and southern-most...
