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 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 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 Geochemistry of soils and other regoliths collected and analyzed by Hans Shacklette and colleagues from 1958 until about 1976.
Depositional Setting and Geochemistry of Phosphorites and Metalliferous Black Shales in the Carboniferous-Permian Lisburne Group, Northern Alaska The purpose of this paper is to present new sedimentological, paleontological, and geochemical data that allow us to define the geographic and stratigraphic extent and depositional setting of these temporally unusual phosphorites.
Environmental characteristics of the abandoned Greenwood Mine area, Prince William Forest Park, Virginia; implications for mercury geochemistry Water quality data for the area include pH, dissolved oxygen, alkalinity, total acid soluble and dissolved major and trace element concentrations for sites around the mine workings.
Geochemical data from groundwater at the proposed Dewey Burdock uranium in-situ recovery mine, Edgemont, South Dakota Groundwater geochemistry data from samples that were collected in June 2011 to better understand the hydrogeologic system in the area surrounding the proposed mine site.
Geochemistry of sediments in the US from the PLUTO database 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 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.
Geochemistry of soils in the US from the RASS database Geochemical data for soils collected by USGS personnel and analyzed by the USGS. These data were originally entered into the Rock Analysis Storage System (RASS), a database that is now merged into the National Geochemistry Database.
Geochemistry of stream sediments in the US from the NURE-HSSR database National-scale geochemical analysis of stream sediments and soils in the US collected and analyzed under the National Uranium Resource Evaluation program.
Geochemistry of water samples in the US from the NURE-HSSR database National-scale geochemical analysis of water samples in the US collected and analyzed under the National Uranium Resource Evaluation program.
Geospatial database for regional environmental assessment of central Colorado Study focusing on the effects of historical mining on Forest Service lands in this area.
Local-area-enhanced, 2.5-meter resolution natural-color and color-infrared satellite-image mosaics of the Bakhud mineral district in Afghanistan GeoTIFF rendition of locally enhanced ALOS image mosaics for this area known to contain industrial fluorite deposits.
Quality of water and sediment in streams affected by historical mining, and quality of mine tailings, in the Rio Grande/Río Bravo basin, Big Bend area of the United States and Mexico, August 2002 Geochemical data for stream water, sediments, and mine tailings in this area
Spring runoff water-chemistry data from the Standard Mine and Elk Creek, Gunnison County, Colorado, 2010 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.
Synthesis of petrographic, geochemical, and isotopic data for the Boulder batholith, southwest Montana Geochemical and mineralogical analyses of plutonic rock samples
National Geochemical Database: Rock 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 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.
