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. It includes the original MRDS and MAS/MILS data.
Information on sediment-hosted zinc-lead deposits from around the world with grade and tonnage models, a general classification based on geologic setting, mineralogy, with data allowing locations of these deposits to be plotted using GIS.
Global compilation of information on the sediment-hosted Pb-Zn deposits traditionally called sedimentary exhalative (SEDEX) and Mississippi Valley Type (MVT) deposits, including updated updated grade and tonnage data.
Information on carbonatite deposits containing niobium and rare earth elements from around the world with grade and tonnage models, geologic setting, mineralogy, with data allowing locations of these deposits to be plotted using GIS.
Location, geologic and mineral economic data for world rare earth mines, deposits, and occurrences compiled from published and non-published sources. Geographic coordinates are provided for 577 of the 799 deposits described here.
Scanned documents describing applications for Federal assistance in exploring for certain strategic and critical minerals, including where the deposits were examined what minerals were found, and whether mining had occurred. These files span the years 1950 to 1974.
Seventy-seven major components of the North American continent were delineated at a general scale (1:5,000,000); including the general composition, geological environment, and types of primary metals endowments that can be expected in each domain.
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".
Databases containing chemical analyses of sediments and soils that were conducted many years ago; some remain classical work held in high esteem for their time, but all are superseded by later compilations and more precise analytical methods.
Measurements of the gravitational field vary slightly from place to place due to the composition and structure of Earth's crust. This digital grid describes the Bouguer gravity anomaly for the conterminous US.
Measurements of the gravitational field vary slightly from place to place due to the composition and structure of Earth's crust. This digital grid describes the isostatic residual gravity anomaly for the conterminous US.
Gridded data generated by aerial sensing of radiation emanating from the earth's surface provides general estimates of the geographic distribution of Uranium, Thorium, and Potassium in surficial and bedrock units. Covers the conterminous US, parts of Canada and parts of Alaska.
