Geology, Minerals, Energy, and Geophysics Science Center

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!

Geochemistry and radiogenic isotopes constrain the mantle source region of the Mountain Pass Intrusive Suite, California

The Mountain Pass carbonatite stock is the largest rare earth element (REE) deposit and only active REE mine in the United States. The carbonatite intrusion and spatially associated alkaline silicate intrusions constitute the Mountain Pass Intrusive Suite, which is located within the Mojave Province in California. Both the carbonatite and the alkaline silicate rocks are enriched in large...

Preliminary depth to basement modeling at Salton Sea, California

The San Andreas Fault – Imperial Fault (SAF-IF) transtensional step-over zone along the southern margin of the Salton Sea hosts substantial geothermal production and lithium brine resources. Recent volcanism at the Salton Buttes and active seismicity along the SAFIF fault system highlight active tectonic and magmatic processes that pose natural hazards and may impact energy and mineral...

Life Cycle of Critical Minerals: A Balanced Approach to Meeting Our Nation's Resource Demands

Critical minerals are essential to the Nation’s economy and security. Demand for critical minerals is increasing, and it is essential to balance the societal need for these minerals with efforts to understand the effects of mining on other natural resources and to develop techniques to minimize these effects. The USGS Minerals Resources Life Cycle Integrated Science Team (IST) focuses on the life...

Geology of the eastern Piedmont and upper Coastal Plain along the Fall Zone, Virginia to Georgia

This USGS NCGMP Project aims to fill the void in geologic map coverage along the Fall Zone from southeastern Virginia to central Georgia, for critical mineral research, earthquake hazards, and interstate correlation. We are also forging strong cooperative ties within the NCGMP by combining resources across all three Program components by supporting Virginia Energy (Virginia Geological Survey), the...

Map of the Hurricane Helene landslide hazard estimates with the highest hazard being around the mountains.

2024 Hurricane Helene Landslide Hazards

Hurricane Helene produced widespread and damaging landslides. The USGS is mapping landslides to support our partners. This page provides information about the extent and severity of landslide impacts. Hurricane Helene made landfall in Florida as a Category 4 storm on Thursday, September 26th, 2024. The hurricane continued across the southern Appalachian Mountains producing record rainfall. This...
