We are approximately 100 dedicated professionals based in the Denver, Colorado offices of the U.S. Geological Survey. We conduct objective scientific investigations that are focused on answering societally relevant questions posed by our clients and collaborators, especially the Mineral Resources Program. The Science Center is a very diverse group of geologists, geochemists, remote sensing specialists, and geochronologists. We were formed in 1995 during reorganization of the USGS Geologic Division by consolidating the former Branches of Geophysics, Geochemistry, Central Mineral Resources, and part of the Branch of Resource Analysis. In October 1999, the former Central Region Mineral Resources Team was cleaved to yield the current Central Mineral and Environmental Resources Science Center and the Crustal Geophysics and Geochemistry Science Center.
