Earth Mapping Resources Initiative (Earth MRI)

Home

The goal of Earth MRI is to improve our knowledge of the geologic framework in the United States and to identify areas that may have the potential to contain undiscovered critical mineral resources. Enhancement of our domestic mineral supply will decrease the Nation’s reliance on foreign sources of minerals that are fundamental to our security and economy.

Mineral Science Reaches New Heights

When learning more about ancient rocks buried deep beneath the surface of the Earth, it may seem surprising to use futuristic technologies flown hundreds of feet in the air, but that has been central to the USGS Earth Mapping Resource Initiative. One year in, it’s time to take stock of what Earth MRI has achieved & where it’s going, using the results of a recent survey to lead the way.

Technical overview of the U.S. Geological Survey Earth Mapping Resources Initiative (Earth MRI)

The Earth Mapping Resources Initiative (Earth MRI) was developed by the U.S. Geological Survey in response to a Federal directive calling on various Federal agencies to address potential vulnerabilities in the Nation’s supply of critical mineral resources. The primary purpose of this initiative is to identify potentially mineralized areas...

Focus areas for data acquisition for potential domestic resources of 11 critical minerals in the conterminous United States, Hawaii, and Puerto Rico—Aluminum, cobalt, graphite, lithium, niobium, platinum-group elements, rare earth elements, tantalum, tin, titanium, and tungsten

In response to a need for information on potential domestic sources of critical minerals, the Earth Mapping Resources Initiative (Earth MRI) was established to identify and prioritize areas for acquisition of new geologic mapping, geophysical data, and elevation data to improve our knowledge of the geologic framework of the United States. Phase 1...
