Maps and data showing the geographic distribution of surficial minerals likely produced by hydrothermal alteration, which may indicate areas permissive of gold and copper mineral deposits.

Maps and data showing the geographic distribution of surficial minerals likely produced by hydrothermal alteration, which may indicate areas permissive of gold and copper mineral deposits.

Detailed descriptions of more than 200 mineral districts, mines, and mineral occurrences (deposits, prospects, and showings) within the United States that are reported to contain substantial enrichment of rare earth elements.

Results of a computational geospatial analysis (linear deconvolution) of thermal infrared emissivity imagery to determine the variation of mineralogical composition of aeolian deposits. Minerals include calcite, potassium feldspar, plagioclase, and quartz. Data are provided in GeoTiff format.

Locations of mineral occurrences, mines, mining and mineral districts and sites of active mineral exploration within or near the Department of the Interior (DOI) Sagebrush Focal Areas in Montana, Wyoming and Utah, central Idaho, and the Oregon-Nevada-Idaho border area. Data are provided in Esri file geodatabase and shapefile formats.

Chemistry and geologic information for historic ore and ore-related rock samples from mineral deposits in the United States and from archetypal deposits from 27 other countries. Data are provide in Microsoft Access, Microsoft Excel, and CSV formats.

Locations, extent, and detailed characteristics and history of mineral deposits containing this commodity, including history of production, resource estimates, and extent of surface workings. Data are provided in Esri file geodatabase, shapefile, and CSV formats.
