Geology, Geophysics, and Geochemistry Science Center

Economic and Framework Geology

The Economic and Framework Geology Branch studies the occurrence and formation processes of earth materials that can be used for economic, technological, or industrial purposes. The Branch uses several tools, including exploration geochemistry, geologic mapping and field observations combined with geochronology studies, tectonics, structural geology, and crustal fluid flow to advance understanding of the controls on orebody formation in the Earth’s crust. The Branch combines information on framework geology, mineral deposit models, geophysical setting, geochemistry, and environmental signatures of ore deposits to develop specialized mineral deposit databases and provide robust assessments of mineral commodities and their environmental expressions in support of land management decisions and resource management.
