Rhenium is a rare metal that has an extremely high melting point and a heat-stable crystalline structure. It is used in high-temperature superalloys, to make turbine blades for jet aircraft engines and is a catalyst for petroleum refining.
Explains how and where rhenium 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 rhenium might be found.
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.
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.
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.
Approximate locations and short descriptions of mines, deposits, and districts where critical minerals are found. The critical minerals are discussed in USGS Professional Paper 1802 many of these locations are described in further detail in that report.
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.
