Earth Mapping Resources Initiative (Earth MRI)
Earth MRI is modernizing mapping of the Nation’s surface and subsurface. We deliver high-quality data needed to understand our Nation’s geology and inform decisions about how the Nation will meet its evolving mineral needs.

National- to continental-scale governmental geophysical efforts for critical mineral mapping, USA
The U.S. Geological Survey (USGS) has established robust collaborations with domestic state and international geological surveys to provide geophysical and other types of earth science data that act to underpin critical mineral research efforts across the United States, Canada, and Australia. The Earth Mapping Resource Initiative (EMRI) is a national-scale collaborative effort with state...
Rift basins and intraplate earthquakes: New high-resolution aeromagnetic data provide insights into buried structures of the Charleston, South Carolina seismic zone
The delineation of faults that pose seismic risk in intraplate seismic zones and the mapping of features associated with failed rift basins can help our understanding of links between the two. We use new high-resolution aeromagnetic data, previous borehole sample information, and reprocessed seismic reflection profiles to image subsurface structures and evaluate recent fault activity...
Ediacaran-Ordovician magmatism and REE mineralization in the Wet Mountains, Colorado, USA: Implications for failed continental rifting
Structures associated with Ediacaran-Ordovician alkaline magmatism and the timing of rare earth element (REE) mineralization in the Wet Mountains, CO, were analyzed using field, geophysical, and U-Th-Pb isotope methods to interpret their tectonic setting in the context of previously proposed rift models. The Wet Mountains are known for thorium and REE mineralization associated with...

Earth MRI Progress
Earth MRI is a national effort to map critical mineral resources needed to drive the U.S. economy and national security, searching below ground and in tailings from old mines. As directed by the Energy Act of 2020, the U.S. Geological Survey has identified 50 critical minerals essential to the U.S. economy and national security, with a supply chain vulnerable to disruption. We partner on this...

Geologic Map of Alaska
In January 2016, the U.S. Geological Survey released the first ever digital geologic map of Alaska. This map reflects more than a century of work and provides a visual context for the abundant mineral and energy resources found throughout the state. The map also is available to use in three different formats: a professional GIS database, a public interactive version via a web browser, and an...
