Geology, Energy, and Minerals Mission Area

We are the Nation’s primary source of impartial scientific information on geologic energy and mineral resources and their supply chains. We deliver actionable science that informs crucial resource management decisions and investments impacting the Nation.

Our Earth MRI initiative is mapping geology and mineral resources across the Nation. We also lead development of the List of Critical Minerals.

Quantitative mineral resource assessment of lithium pegmatite deposits in the Appalachian Orogen, USA Quantitative mineral resource assessment of lithium pegmatite deposits in the Appalachian Orogen, USA

Lithium is classified as a U.S. critical mineral commodity, and its demand is projected to drastically increase through 2040, driven by electric vehicle production and energy storage applications (IEA 2021).Most global lithium production is not in the United States increasing vulnerability to a supply disruption. The U.S. Geological Survey is actively assessing domestic lithium deposits...

Petrogenesis and mineralization potential of the Bradley Peak komatiitic basalts, Wyoming Province Petrogenesis and mineralization potential of the Bradley Peak komatiitic basalts, Wyoming Province

The ca. 2.72 Ga Bradley Peak greenstone terrane in the Wyoming Province contains spinifex- and cumulate-textured komatiitic volcanic rocks that may host Ni-Cu-PGE sulfide mineralization. New whole rock geochemistry classifies these rocks as Al-undepleted komatiitic basalts derived from a parental melt with ~17 wt. % MgO. Isotopic data (Sm-Nd, Re-Os) and REE profiles suggest a plume...

Gravity and magnetic surveys of the Skaergaard intrusion, East Greenland Gravity and magnetic surveys of the Skaergaard intrusion, East Greenland

Aeromagnetic and gravity surveys of the Skaergaard intrusion in East Greenland were carried out in July–August 1971 as part of a grant to the University of Oregon Center for Volcanology to refine the models of crystallization and differentiation of the intrusion, specifically to test whether the intrusion is underlain by dense rocks of a reservoir 20 kilometers (km) thick (referred to as...
