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.
Geochemical analyses of sediment samples throughout the U.S. collected by the hydrogeochemical and stream sediment reconnaissance (HSSR) phase of the National Uranium Resource Evaluation (NURE) program. This database contains 397,625 records.
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 USGS. These data were part of the Rock Analysis Storage System and are now merged into the National Geochemistry Database.
Geochemical analyses of water samples throughout the U.S. collected by the hydrogeochemical and stream sediment reconnaissance (HSSR) phase of the National Uranium Resource Evaluation (NURE) program. This database contains 335,547 records.
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.
