Results 1 - 14 of 14 listed by similarity [list alphabetically]
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.
Aqueous geochemical data from the analysis of stream-water samples collected in June and August 2008--Taylor Mountains 1:250,000- and Dillingham D-4 1:63,360-scale quadrangles, Alaska [New Window]
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.
Geochemical data from waters in Prospect Gulch, San Juan County, Colorado, that span pre- and post-Lark Mine remediation [New Window]
Water samples near this abandoned mine were analyzed for specific conductance, pH, temperature, and dissolved oxygen with handheld field meters, and metals were analyzed using inductively coupled plasma-mass spectrometry.
Geochemistry of sediments in the US from the PLUTO database [New Window]
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.
Geochemistry of soils in the US from the PLUTO database [New Window]
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.
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.
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.
Physical, chemical, and mineralogical data from surficial deposits, groundwater levels, and water composition in the area of Franklin Lake playa and Ash Meadows, California and Nevada [New Window]
Presents data and describes the methods used to determine the physical attributes, as well as the chemical and mineralogical composition of surficial deposits; groundwater levels; and water composition in this area.
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.
Spring runoff water-chemistry data from the Standard Mine and Elk Creek, Gunnison County, Colorado, 2010 [New Window]
Periodic sampling of water during the spring of 2010 was carried out to understand the range and timing of variation in pH and metal concentration, and help evaluate variation in water quality during spring runoff.
