Select data resources by choosing geographic areas by name from lists of countries, states, and counties; named USGS map quadrangles; and hierarchical hydrologic units (drainage basins).
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 VMS deposits from around the world with new grade and tonnage models for three subtypes of VMS deposits and data allowing locations of all deposits to be plotted using GIS.
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.
Location and characteristics of 1,124 individual podiform chromite mineral deposits, with grade and tonnage models for chromium as well as several related elements.
Mine plants and operations for commodities monitored by the National Minerals Information Center of the USGS. Operations included are those considered active in 2003 and surveyed by the USGS.
The value of mineral production by state in the United States. The data represent commodities covered by the National Minerals Information Center of the U.S. Geological Survey.
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.
A digital version of the King and Beikman (1974) Geologic Map of the United States, originally published at a scale of 1:2,500,000. It excludes Alaska and Hawaii.
Radiometric ages of rocks or minerals sampled from Alaska. The data were collected from professional publications and/or received from researchers and used by permission.
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".
National-scale geochemical analysis of stream sediments and soils in the US, from existing data, reanalysis of existing samples, and new sampling. Goal for sample density is one per 289 square km.
National-scale geochemical analysis of stream sediments and soils in the US collected and analyzed under the National Uranium Resource Evaluation program.
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.
Airborne measurement of the earth's magnetic field over all of North America provides gridded data describing the magnetic anomaly caused by variations in earth materials and structure.
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.
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.
