Welcome to the Center for Gravity, Electrical & Magnetic Studies (CGEM) in the Department of Geophysics at the Colorado School of Mines. CGEM is an academic research center that focuses on the quantitative interpretation of gravity, magnetic, electrical and electromagnetic data in applied geophysics. The center brings together the diverse expertise of faculty and students in these different geophysical methods and works towards advancing the state of art in geophysical data interpretation for real-world problems. The emphases of CGEM research are processing and inversion of applied geophysical data. The primary areas of application include petroleum exploration, mineral exploration,unexploded ordnance (UXO) detection & discrimination, and near surface problems. In addition, environmental problems, natural hazard monitoring, archaeological mapping, hydro-geophysics and crustal study are also within the scope of the center.

There are currently six major research groups within the center: Gravity and Magnetics Research Consortium (GMRC), Unexploded Ordnance Research Group (UXO), Geothermal Exploration Group, Near Surface Environmental Group, and two independently sponsored groups focused on current needs of the sponsoring companies. Research fundings are provided by both industry and government agencies.
