A synthesis of the Mineral Resources Program's past and future research directions in the western U.S. on metal contamination due to mineral deposits and mining and the environmental effects on living organisms. Chapters 1, 4, and 6 as PDF files.
Estimates of known and undiscovered copper resources total nearly 60 million metric tons of copper. Iron resources in known deposits total 2200 million metric tons of ore. Twenty mineralized areas meriting further study were identified.
Estimates of uranium resources affected by land withdrawal, effects of previous breccia-pipe mining, water-chemistry data for streams and springs, and potential biological pathways of exposure to uranium and associated contaminants.
Report of research on the Carolina slate belt and gold deposits in Virginia, North Carolina, South Carolina, and Georgia with geologic mapping, mineralogic, geochemical, and fluid evolution studies, radiogenic dating, and stable isotope studies.
Shows where important mineral resources are located in Afghanistan, the type of deposits there, the commodities that are present, and describes the data available to support further exploration and exploitation of these resources.
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.
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.
