GMEG - Mineral and Environmental Resources
Project status is complete. Please check the project list for currently active projects
Robust quantitative mineral resource assessments require both comprehensive knowledge of the regional geology and the mineral deposits of the assessment areas, and detailed genetic models of deposit types used in the assessments. A comprehensive understanding of the geology, hydrothermal systems, and mineral resources of the Cascades arcs and central California Coast Ranges is essential for land-use managers to be able to plan for future multiple uses and for increasing reliability of the forthcoming National Mineral Resource Assessment. Areas to the east of the western Great Basin (including the Humboldt River Basin), as well as the Western Cascades arc in Oregon and Washington, recently have received comprehensive geologic and mineral resource investigations. However, mineral resource information for much of the northwestern Great Basin and Modoc Plateau south of the High Cascades in California and for the central Coast Ranges is not comprehensive or the existing data compilations are outdated, creating a critical gap in regional geologic and resource knowledge and databases.
Major objectives of the project are:
