This study delineated permissive areas for undiscovered porphyry copper deposits, compiled a database of known deposits and significant prospects, estimated undiscovered deposits within those areas and made probabilistic estimates of their metal content

Regional locations and estimates of the probable amounts of undiscovered resources of copper, platinum-group elements, and potash in selected types of mineral deposits to depths of 1 to 3 kilometers below the surface of the earth worldwide.

Delineated areas of the world that are geologically permissive for the occurrence of undiscovered selected nonfuel mineral resources together with estimates of the quantity and quality of the resources

Database of mines and mineral plants through 2003

Location, type, mineralogy, name, tonnage and grade, and geological setting for 120 deposits of this type. The US has no active nickel mines or nickel reserves.

Geochemical analysis of rock samples collected and analyzed by the USGS. This dataset includes and supersedes rock data formerly released as "Geochemistry of igneous rocks in the US extracted from the PLUTO database"

MRDS describes metallic and nonmetallic mineral resources throughout the world. Included are deposit name, location, commodity, deposit description, geologic characteristics, production, reserves, resources, and references.

Location and characteristics of 1,124 individual mineral deposits of this type, with grade and tonnage models for chromium as well as several related elements.

Geochemical analysis of sediment samples from the National Geochemical Database. Primarily inorganic elemental concentrations, most samples are of stream sediment in the continental US and Alaska.

Geochemistry of concentrates from the National Geochemical Database. Primarily inorganic elemental concentrations, most samples are from the continental US and Alaska.

Deposits, prospects, and permissive tracts for porphyry and sediment-hosted copper resources worldwide, with estimates of undiscovered copper resources.

Geochemical data for stratigraphic rock sequences containing dominantly fine-grained clastic rocks with appreciable organic carbon (above 0.5 weight percent), usually known as 'black shale facies examples' but including all fine-grained clastic rocks such as argillite, mudstone, claystone, and their low-medium grade metamorphic equivalents. Data are provide in Microsoft Access and tab-delimited text formats.

Ar/Ar data are for samples that record the metamorphic deformation of the ophiolite. Data are provided in CSV format.

Statistics for over 88 nonfuel mineral commodities including items such as production, imports, exports, price, stocks, apparent consumption, and/or net import reliance for nonfuel mineral commodities. Data are provided in CSV format.
