National-scale geochemical analysis of stream sediments and soils in the US collected and analyzed under the National Uranium Resource Evaluation program.
National Geochemical Database: Rock [New Window]
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 geochemical survey database [New Window]
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.
PDF Rare earth element mineralogy, geochemistry, and preliminary resource assessment of the Khanneshin carbonatite complex, Helmand Province, Afghanistan [New Window]
Geological setting, characteristics of the deposit itself, and detailed geochemical analyses of rocks in and around the deposit.
PDF Review of samples of tailings, soils and stream sediment adjacent to and downstream from the Ruth Mine, Inyo County, California [New Window]
Detailed study of mine waste material and sediments from streams passing through it. Arsenic is the main contaminant of interest here.
PDF Review of samples of water, sediment, tailings, and biota at the Little Bonanza mercury mine, San Luis Obispo County, California [New Window]
Data from field sampling of mine tailings, wasterock, sediment, water, and biota at the mine in 2010. Results permit a preliminary assessment of the mining sources of Hg and associated chemicals that could produce elevated levels of monomethylmercury.
