A comprehensive database of Alaskan mineral deposits compiled from the published literature and from unpublished reports and data from industry, the US Bureau of Land Management, and USGS.
Geochemical data for unconsolidated sediments (stream sediments, lake sediments, etc.) collected in the US and analyzed by the USGS. These data were originally entered in the PLUTO database, which is now merged into the National Geochemistry Database.
Geochemical data for soils collected in the United States and analyzed by the USGS. The data were originally entered into the in-house PLUTO database. This is a subset of DDS-47.
Geochemical data for soils collected by USGS personnel and analyzed by the USGS. These data were originally entered into the Rock Analysis Storage System (RASS), a database that is now merged into the National Geochemistry Database.
National-scale geochemical analysis of stream sediments and soils in the US collected and analyzed under the National Uranium Resource Evaluation program.
Geochemical data for unconsolidated sediments (stream sediments, lake sediments, etc.) collected by USGS personnel and analyzed by USGS. These data were part of the Rock Analysis Storage System and are now merged into the National Geochemistry 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.
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.
Mine plants and operations for commodities monitored by the Minerals Information Team of the USGS. Operations included are those considered active in 2003 and surveyed by the USGS.
A subset of the National Geochemical Database (as of 1995). Shows the distribution of published K/Ar and Ar/Ar age determinations in the US. Sample location, rock description, analytical data, age, interpretation, and bibliographic reference are given.
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.
