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, find new critical and other mineral resources, and inform decisions about how the Nation will meet its evolving needs.

Geochemical, mineralogical, and isotopic evidence for multi-stage genesis of the Hicks Dome REE + Y-HFSE-fluorite deposit, Illinois, USA Geochemical, mineralogical, and isotopic evidence for multi-stage genesis of the Hicks Dome REE + Y-HFSE-fluorite deposit, Illinois, USA
Hicks Dome hosts breccias enriched in rare earth elements (REE), Y, Th, F, Ba, Ti, Nb, and Be, alongside spatially associated lamprophyre dikes (ca. 271 Ma). Hicks Dome is located within the Illinois–Kentucky Fluorspar District, which hosts fluorite, Pb–Zn, and barite resources. This study investigates the genetic relationships between Hicks Dome mineralization in breccias, alkaline...

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...
Alaska Earth Mapping Resources Initiative (Earth MRI)
Our objective is to provide a strategic framework for planning, coordination, and execution of the USGS Earth Mapping Resources Initiative (Earth MRI) in Alaska. Earth MRI aims to improve knowledge of the U.S. geologic framework through new geological and geophysical mapping and to identify areas that have the potential to contain undiscovered critical mineral resources.
Earth MRI Progress
The U.S. needs high-quality geologic data to identify critical and other mineral resources, energy resources, make important land use decisions, and identify natural disasters. Since 2019, Earth MRI has advanced modern mapping of the US through the collection of geophysical, geochemical, geologic, topographic, hyperspectral, mine waste and other data, focusing on areas with the potential for...
