Critical Minerals Mapping Initiative (CMMI)
The USGS, in combination with Geoscience Australia and the Geological Survey of Canada, formed the Critical Minerals Mapping Initiative (CMMI) in 2019 to combine expertise and collaboratively conduct research on critical mineral resources.Earth Mapping Resources Initiative (Earth MRI)
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. - Data
Airborne magnetic and radiometric survey, western Arkansas, 2022
This publication provides digital flight line data for a high-resolution magnetic and radiometric survey over part of western Arkansas. The airborne geophysical survey was funded by the USGS National Cooperative Geologic Mapping Program. The survey covers a rectangular area 91.55 by 92.15 kilometers (km) over the transition between the Ouachita Mountains and Ozark Plateau physiographic provinces a
