Digital geologic maps of the US states with consistent lithology, age, GIS database structure, and format

Aerial surveys of magnetic anomaly and gamma ray emission; older surveys were analog record which have been digitized, newer surveys collected data in digital form.

National Mineral Resource Assessment 1998: Estimates of the number of undiscovered mineral resources of gold, silver, copper, lead, and zinc within identified permissive tracts (geographic areas in which mineral deposits may form).

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.

Regional locations and general geologic setting of known deposits of major nonfuel mineral commodities. Originally compiled in five parts by diverse authors, combined here for convenience despite likely inconsistencies among the regional reports.

National-scale geochemical analysis of stream sediments and soils in the US collected and analyzed under the National Uranium Resource Evaluation program.

This report provides information on sediment-hosted zinc-lead mineral deposits based on the geologic settings that are observed on regional geologic maps.

Approximate locations and short descriptions of mines, deposits, and districts where critical minerals are found. The critical minerals are discussed in USGS Professional Paper 1802 many of these locations are described in further detail in that report.

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"

Information on porphyry copper 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.

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.

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.

Radiometric ages of geological materials by K-Ar, Rb-Sr, Sm-Nd, fission track, and U-Th-Pb dating methods. A revision of DDS-14 correcting locations and providing the data in more convenient formats.

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

Symbols indicating mining-related features digitized from historical USGS topographic maps in the western part of the conterminous US. Includes prospect pits, mine shafts and adits, quarries, open-pit mines, tailings piles and ponds, gravel and borrow pit

A developing national-scale geospatial database that will be an authoritative source of information on the most important mines, mineral deposits, and mineral districts of the United States.
