Measurements on 92 samples, including pH, conductivity, water temperature, major cation and anion concentrations, and trace-element concentrations.
Aqueous geochemical data from the analysis of stream-water samples collected in June and July 2006-Taylor Mountains 1:250,00-scale quadrangle, Alaska [New Window]
Analyses of 72 water samples include pH, conductivity, water temperature, major cation and anion concentrations, trace-element concentrations, and dissolved organic-carbon concentrations.
Chemical analyses of soils and other surficial materials of the conterminous US [New Window]
Geochemistry of soils and other regoliths collected and analyzed by Hans Shacklette and colleagues from 1958 until about 1976.
Geospatial database for regional environmental assessment of central Colorado [New Window]
Study focusing on the effects of historical mining on Forest Service lands in this area.
Lithogeochemistry of mineralized and altered rock samples from the northern Talkeetna Mountains, south-central Alaska [New Window]
Chemical analysis of 201 samples of rocks thought to be altered or mineralized in an area containing numerous mines.
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 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.
Aquatic assessment of the Ely Copper Mine Superfund site, Vershire, Vermont [New Window]
A wide variety of geochemical analyses show strong local impact on water quality in this area of historical copper mining.
