This data release contains mineral resource and geology data for metallic and nonmetallic mineral sites in Wyoming. Data is provided in both spreadsheet format (Microsoft Excel) and in GIS ArcView and MapInfo. Text available in PDF format.
Number and types of mineral facilities in the area affected by the earthquake, with comments on physical infrastructure that these facilities are likely to require.
Contaminants from mines move more easily from ore materials and mine waste piles to surrounding estuaries and living organisms when water moves through the mine site. Geochemical results shown here will help people mitigate the negative effects.
Reviews how coal fires occur, how they can be detected by airborne and remote surveys, and, most importantly, the impact coal-fire emissions may have on the environment and human health, especially mercury, carbon dioxide, carbon monoxide, and methane.
Explains how industrial minerals are produced and overseen through governmental regulation, and describes the industrial mineral resources of central Colorado.
Description and photos related to the Picher Mining District in Oklahoma, once a primary U.S. source of lead and zinc and now the largest superfund site in the U.S. with millions of cubic yards of mine tailings (locally known as "chat") remaining.
Presentation describing uses of rare earth elements, why they are important, where they occur and are produced, and aspects of the economics of production and consumption with emphasis on sites that might be developed for production.
Listing of USGS research and monitoring projects on mine drainage, in order to promote cooperation and collaboration among scientists working on problems related to mining and the environment.
Outlines processes that control the release of metals and acidic waters from inactive mines and mineralized areas, the transport of metals and acidic waters to streams, and the fate and effect of metals and acidity on downstream ecosystems.
Historical gold mining has left this area susceptible to mercury contamination. Elevated concentrations of mercury in the fish are well documented here.
Collection of six short papers related to the mercury geochemical society, the study of mercury in coal, concentrations in sediment, soil, water, and fish collected near mercury and gold mines, and volanic emissions of mercury.
Coordinated studies of the effect of historical mining for mercury, origin and composition of metals in groundwaters and surface waters, history of volcanic and intrusive activity, and the complex geological history of this area.
