Mineral Resources On-Line Spatial Data
Chemical techniques used to identify the composition of substances.
This category is also used for detection (chemical), geochemical surveys, leaching (analytical method), mineralogical analysis, and nuclear magnetic resonance spectroscopy.
- Geochemical analysis of soils and sediments, Coeur d'Alene drainage basin, Idaho: Sampling, analytical methods, and results [New Window]
- Chemical composition of sediments and soils are of interest because of the potential for human and wildlife health impacts from high metal contents due to over 100 years of mining activity.
- Major- and trace-element concentrations in soils from two geochemical surveys (1972 and 2005) of the Denver, Colorado, metropolitan area [New Window]
- Analyses of about 900 samples by ICP-MS, ICP-AES, and hydride generation-atomic absorption spectrometry. The samples collected in 2005 were also analyzed by a cold vapor-atomic absorption method for mercury.
- Stream-Sediment Geochemistry in Mining-Impacted Drainages of the Yankee Fork of the Salmon River, Custer County, Idaho [New Window]
- Analysis of stream sediments to assess the geochemistry, in particular the mercury and selenium contents, of mining-impacted sediments in the study area
- Geochemical data from analyses of rock, sediment, water, and solid-phase leaching at the Tuba City open dump, Tuba City, Arizona [New Window]
- Study of sources and resulting transport of radionuclides and other dissolved constituents in the surrounding ground water.
- Regional geochemical results from the reanalysis of NURE stream sediment samples--Eagle 3 degree quadrangle, east-central Alaska [New Window]
- Reanalyses of NURE sediment samples in the Fortymile mining district, east-central Alaska. Provides new lower limits for some elements. Compares data from newer analytical techniques with original NURE data.
- Alaska Geochemical Database (AGDB)-Geochemical data for rock, sediment, soil, mineral, and concentrate sample media [New Window]
- Geochemical analyses of rocks, mineral separates, bulk samples from lake and stream sediments, heavy mineral concentrates, and soils collected by USGS from 1962 to 2009.
- 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.
- Central Colorado Assessment Project (CCAP)-Geochemical data for rock, sediment, soil, and concentrate sample media [New Window]
- Chemical analysis of 47,478 samples of various geological materials to facilitate geologic mapping, petrologic studies, mineral resource assessment, and similar regional environmental assessements.
- Determination of premining geochemical background and delineation of extent of sediment contamination in Blue Creek downstream from Midnite Mine, Stevens county, Washington [New Window]
- Geochemical and radionuclide analyses of surface samples and cores taken near the outflow of this old uranium mine.
