A wide variety of geochemical analyses show strong local impact on water quality in this area of historical copper mining.
Measurements on 92 samples, including pH, conductivity, water temperature, major cation and anion concentrations, and trace-element concentrations.
Analyses of 72 water samples include pH, conductivity, water temperature, major cation and anion concentrations, trace-element concentrations, and dissolved organic-carbon concentrations.
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.
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.
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.
This report presents chemical characteristics of transient unsaturated-zone water collected by lysimeter from the Manning Canyon repository site in Utah. Data collected by U.S. Geological Survey and U.S. Department of the Interior, Bureau of Land Manageme
Surficial geochemical methods used to identify subsurface mineral deposits covered by alluvium. Can a geophysical anomaly, interpreted as a buried granite pluton, be discerned from the geochemical characteristics of overlying Quaternary sediments?
National-scale geochemical analysis of stream sediments and soils in the US collected and analyzed under the National Uranium Resource Evaluation program.
National-scale geochemical analysis of water samples in the US collected and analyzed under the National Uranium Resource Evaluation program.
Study focusing on the effects of historical mining on Forest Service lands in this area.
GeoTIFF rendition of locally enhanced ALOS image mosaics for this area known to contain rare-earth element deposits.
This report releases data for waters in which naturally occurring acid-rock drainage occurs but acid-mine drainage from historical mining continues to contribute dissolved metals further degrading preexisting water quality.
Geochemistry of concentrates from the National Geochemical Database. Primarily inorganic elemental concentrations, most samples are from the continental US and Alaska.
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"
Geochemical analysis of sediment samples from the National Geochemical Database. Primarily inorganic elemental concentrations, most samples are of stream sediment in the continental US and Alaska.
Geochemical analysis of soil samples from the National Geochemical Database. Primarily inorganic elemental concentrations, most samples are from the continental US and Alaska.
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.
Geological setting, characteristics of the deposit itself, and detailed geochemical analyses of rocks in and around the deposit.
Location, geologic and mineral economic data for world rare earth mines, deposits, and occurrences compiled from published and non-published sources. Geographic coordinates are provided for 577 of the 799 deposits described here.
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.
Data in this report will be used to better understand the processes that control epithermal mineral-deposit formation by attempting to relate the geochemistry of the primary structures that hosted hydrothermal fluid flow to their heat and fluid sources.
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.
Geochemical and mineralogical analyses of plutonic rock samples
Georeferenced images depicting the concentration of 68 chemical elements in the near-surface materials (sediments and soils).
Explains how and where rare-earth resources form and concentrate and how they are used and interact with the environment to affect human and ecosystem health. Discusses supply and demand trends and where undiscovered sources of rare-earths might be found.
This report releases data, cross section, and model information related to the identification of travel paths for groundwater supply and principal stratigraphic and structural features that serve as constraints or conduits for groundwater movement.
