Reconnaissance summary and survey of 1118 indium analyses of a diverse suite of minerals, including monomineralic and polymineralic ores and mineral concentrates, from 12 mineral-deposit types, principally zinc-lead deposits, from 16 countries.

Explains how and where indium 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 indium might be found.

Germanium and indium are used in electronics devices, flat-panel display screens, light-emitting diodes, night vision devices, optical fiber, optical lens systems, and solar power arrays.

Investigates the expanding LED industry and it’s manufacturing complexities. The sources and supply of the select mineral commodities used and the manufacturing process and supply chain are discussed.

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.

Systematic geochemical and mineralogical survey of soil horizons analyzed using a consistent set of methods, sample spacing 1 per 1,600 sq km.

Between 2007 and 2013, the U.S. Geological Survey conducted a low-density (1 site per 1,600 square kilometers, 4,857 sites) geochemical and mineralogical survey of soils in the conterminous United States. The sampling protocol for the national-scale surve

In this area of historical lead-zinc mining activity, studies such as this help to assess the possibility of human exposure to cadmium and lead through eating fish.

Includes all geochemical data generated by each project partnership funded through Earth MRI and will be updated periodically as additional geochemical data from these projects becomes available.

Data portrayed in this portfolio of landscape geochemical maps serve as a geochemical baseline for the region, indicate element abundances characteristic of various lithologic terranes, and identify gross anthropogenic effects of historical mining

Chemical and mineralogical results of a soil study conducted in the lower Rio Grande valley, Texas. 210 samples were collected from soils formed on Holocene alluvial flood-plain and distributary channel deposits of the river valley.

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.

Amounts and global distribution of major consumer, producer, and exchange stocks of selected mineral commodities.

This study summarizes the identified mineral inventory of PGE in South Africa and Zimbabwe and estimates the potential amount of undiscovered PGE resources that may be present in these countries.

The site, on the Wind River Indian Reservation, has Eastern Shoshone and Northern Arapahoe tribes concerned about groundwater and soil contamination. This effort studies geochemical soil variation and compares concentrations with levels established by EPA

Detailed study of mine waste material and sediments from streams passing through it. Arsenic is the main contaminant of interest 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.

Mining districts, mines, and mineral occurrences (deposits and prospects) within the United States that are reported to contain enrichments of rhenium (Re)

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.

Weight percent of 15 mineral groups from 331 samples, geochemical analyses of 58 major and trace-element chemical species from 502 samples taken at 175 sites, along with data from geochemical reference standards and analyses of splits.

Chemical analysis of geological materials at this EPA Superfund site located on lands of the Hopi and Navajo nations, which may contain mine waste.

Geochemical analyses of rock, sediment, soil, mineral, and heavy mineral concentrate samples in Alaska analyzed from 1962 through 2009, with best-value estimates.
