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.
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.
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.
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.
Information on the mineral industry in these countries, the operating status of mining projects through 2014, and coordinated actions by mining companies to support governments and international relief organizations to contain the Ebola outbreak.
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.
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.
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.
