Geology, Energy & Minerals (GEM) Science Center

Comprehensive, Interdisciplinary Research and Surveys

Geology, Energy & Minerals Science Center

Scientists within the GEMSC represent a breadth of programs focused on the USGS mission; Energy Resources Program, Mineral Resources Program, National Cooperative Geologic Mapping Program, and Environmental Health Programs. GEMSC conducts comprehensive, interdisciplinary research and surveys of the origin, occurrence, distribution, quantity, and composition of oil, gas, coal, minerals, and more.

What We Provide

What We Address

River Sampling

GEMSC was established in 2020 through the merger of the Eastern Energy Resources and the Eastern Mineral and Environmental Resources Science Centers. Our work is broadly applicable to current and emerging geology, energy, and minerals issues.

Relating systematic molecular and textural properties of graptolite pyrolyzed via gold tube hydrous pyrolysis: Implications for thermal proxies in lower Paleozoic marine shales

A series of gold tube pyrolysis experiments (72 h, 300–550 °C, 50 MPa) conducted on a graptolite-rich lower Paleozoic marine shale generated pyrolysis residues for a comprehensive evaluation of the molecular and structural variability of three types of graptolite periderm. Organic petrology, Raman spectroscopy, and field emission scanning electron microscopy (FE-SEM) with energy...

Machine learning provides reconnaissance-type estimates of carbon dioxide storage resources in oil and gas reservoirs

Oil and gas reservoirs represent suitable containers to sequester carbon dioxide (CO2) in a supercritical state because they are accessible, reservoir properties are known, and they previously contained stored buoyant fluids. However, planners must quantify the relative magnitude of the CO2 storage resource in these reservoirs to formulate a comprehensive strategy for CO2 mitigation...

Statistical approaches for modeling correlated grade and tonnage distributions and applications for mineral resource assessments

Correlations between grade and tonnage exist in mineral resource data compiled from published reports, but they are not always addressed during quantitative assessment of undiscovered mineral resources. Failure to account for correlated grade and tonnage distributions can result in geologically unrealistic assessment results. Current software tools simulate univariate ore tonnage and...
