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!

Miocene evolution of the Humboldt Current Miocene evolution of the Humboldt Current

Diatom records from the East Pisco Basin (EPB) of southern Peru and offshore Ocean Drilling Program (ODP) Hole 682 A reveal stepwise increases in the primary productivity of the Humboldt Current during the middle and late Miocene. Although diatoms are present back through the late middle Eocene, successively enhanced diatom production occurs during the Miocene in four steps. The first...

Is satellite-derived bathymetry vertical accuracy dependent on satellite mission and processing method? Is satellite-derived bathymetry vertical accuracy dependent on satellite mission and processing method?

This research focusses on three satellite-derived bathymetry methods and optical satellite instruments: (1) a stereo photogrammetry bathymetry module (SaTSeaD) developed for the NASA Ames stereo pipeline open-source software (version 3.6.0) using stereo WorldView data; (2) physics-based radiative transfer equations (PBSDB) using Landsat data; and (3) a modified composite band-ratio...

The geology of Canadian potash: A critical mineral for feeding the world The geology of Canadian potash: A critical mineral for feeding the world

Potash, potassium-bearing water-soluble salt, is the primary global economic source of potassium. Potash is recognized as a critical mineral in Canada as it is the largest source of potassium used in fertilizers. It is essential for global agricultural productivity and food security. Canada is the world’s largest potash exporter with vast deposits in the widely mined Prairie Evaporite of

Large Magmatic Systems for Minerals

This project continues work on large magmatic systems in the U.S., where critical mineral commodities important to clean energy technologies can be concentrated. Modeling of large mafic intrusion extents will continue, and new geophysical methods will be applied to improve understanding of magmatic systems.

Reducing Wildfire Risks with Science

Hotter and drier conditions are making wildfires more intense and destructive across the United States. Science from the USGS Ecosystems Land Change Science Program informs local to national reduction of wildfire hazards, which saves money in avoided losses and fire suppression costs, as well as saves human lives.
