The Michigan Geological Repository for Research and Education (MGRRE) is an important component of the Department of Geosciences and of Western Michigan University. This facility enables faculty to pursue the mission of conducting Michigan subsurface geological research and technology transfer focused on oil and gas exploration and development and carbon dioxide sequestration. MGRRE’s faculty and students also conduct geological research about geothermal energy, glacial geology and mapping, groundwater aquifers, subsurface mineral deposits and the geological history of the Michigan Basin. The 27,000 square-foot MGRRE facility archives the most comprehensive collection of geological samples and data in the state of Michigan, including approximately 530,000 linear feet of rock cores.
