Geology, Minerals, Energy, and Geophysics Science Center

Home

Scientists with the GMEG Science Center work on issues related to geologic processes, mineral and energy resource potential, and past climate, primarily in the Western United States. The science staff includes Geologists, Geophysicists, Geochemists, Biologists, and Geographic Information Systems specialists located in Arizona, California, Nevada, Oregon, and Washington.

Primary Research Direction - What we do.

GMEGSC focuses on Geologic Mapping, Mineral Resources and Mineral Environmental Health, Landslide Hazards, Energy Resources, Earthquake Hazards, and Land Change Science.

Innovation - How we help.

GMEGSC hosts the USGS Innovation Center, which sponsors work with public and private technology partners to design, test, and bring into operation a new generation of technical and engineering tools to address urgent national natural science issues.

Disciplinary Expertise - How we do it.

GMEGSC utilizes Geologic Mapping and Tectonics, Geophysics, Economic Geology, Geochronology, Sedimentary Basin Studies and Energy Assessments, Landslide Hazards, Geomorphology, Paleoclimatology, and many more processes to complete our work!

Digital Gold Rush Depends on Traditional Gold

In 1849, the discovery of gold in California sparked one of the most famous gold rushes in history. Thousands trekked across mountainous terrain to seek the precious metal, with entire industries springing up around the rush. In fact, the desire to understand our mineral resource wealth that led to the creation of the U.S. Geological Survey was in part fueled by gold rushes like this one.

Geologic field photograph map of the Grand Canyon region, 1967–2010

The Grand Canyon geologic field photograph collection contains 1,211 geotagged photographs collected during 43 years of geologic mapping from 1967 to 2010. The photographs document some key geologic features, structures, and rock unit relations that were used to compile nine geologic maps of the Grand Canyon region published at 1:100,000 scale,...

Three-dimensional geologic map of the southern Carson Sink, Nevada, including the Fallon FORGE area

The three-dimensional (3–D) geologic map characterizes the subsurface in the southern Carson Sink region. We created the 3–D map by integrating the results from seismic-reflection, potential-field-geophysical, and lithologic well-logging inves­tigations completed in and around the Fallon FORGE site as part of the U.S. Department of Energy Frontier...

Insights into post-Miocene uplift of the western margin of the Colorado Plateau from the stratigraphic record of the lower Colorado River

The spatial and temporal distribution of Pliocene to Holocene Colorado River deposits (southwestern USA and northwestern Mexico) form a primary data set that records the evolution of a continental-scale river system and helps to delineate and quantify the magnitude of regional deformation. We focus in particular on the age and distribution of...
