Mineral Resources On-Line Spatial Data
Geochemical and stable isotopic data on barren and mineralized drill core in the Devonian Popovich Formation, Screamer sector of the Betze-Post gold deposit, northern Carlin trend, Nevada Detailed chemical and isotopic analysis of host and associated rocks within an area that is currently the largest producer of gold in the US. Part of a study of the hydrothermal activity leading to the formation of these gold deposits.
Alaska Geochemical Database (AGDB)-Geochemical data for rock, sediment, soil, mineral, and concentrate sample media 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.
Alaska Geochemical Database, Version 2.0 (AGDB2)--including "best value" data compilations for rock, sediment, soil, mineral, and concentrate sample media 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 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.
Bedrock and soil geochemistry from Voyageurs National Park, Minnesota Analyses to establish the background and baseline geochemistry for bedrock and soil in the region, and to determine terrestrial mercury sources and sinks in the park
Bedrock soil and lichen geochemistry from Isle Royale National Park, Michigan Geochemical analyses conducted as part of a larger study of the Midcontinent Rift in the Lake Superior region.
Central Colorado Assessment Project (CCAP)-Geochemical data for rock, sediment, soil, and concentrate sample media Chemical analysis of 47,478 samples of various geological materials to facilitate geologic mapping, petrologic studies, mineral resource assessment, and similar regional environmental assessements.
Chemical Composition of Samples Collected from Waste Rock Dumps and Other Mining-Related Features at Selected Phosphate Mines in Southeastern Idaho, Western Wyoming, and Northern Utah Chemical analyses for 31 samples collected from various phosphate mine sites in southeastern Idaho (25), northern Utah (2), and western Wyoming (4)
Chemistry of stream sediments and surface waters in New England Regional data for pH, alkalinity, and specific conductance for stream waters and a multi-element geochemical dataset for stream sediments collected in the New England.
Coal fields of the conterminous United States - National Coal Resource Assessment updated version This map sheet with accompanying Geographic Information System (GIS) project is an update of the existing U.S. Geological Survey (USGS) Conterminous U.S. Coal Fields map compiled using data primarily from the USGS National Coal Resource Assessment (NCRA).
