USGS web services, applications, and data portals in support of Earth MRI are listed below. These are updated with data collected and published under Earth MRI as they become available.

Earth MRI Acquisitions Map

Earth MRI began in 2019 and is a partnership between the USGS and State Geological Surveys to acquire new geologic maps, geophysical surveys, and LiDAR data to better understand the fundamental geologic framework of areas across the Nation with potential for hosting critical mineral resources.

Airborne magnetic and radiometric survey of the southeast Mojave Desert, California and Nevada

A high-resolution airborne magnetic and radiometric survey of the southeast Mojave Desert, parts of California and Nevada was flown by EDCON-PRJ, Inc. from December 13, 2019 to March 21, 2020. The high-resolution fixed-wing survey was flown at a flightline spacing of 200 m, an azimuth of 70 degrees, a nominal elevation above ground of 100 m, and consists of about 17,277 line-kilometers.

Airborne Geophysical Survey Inventory of the US Interactive Application

Feature Layer - data documents the spatial footprint and survey details of airborne geophysical surveys in the United States.

Geologic Map Catalog

Provides access to more than 100,000 geologic maps and other types of geoscience reports and data published from the early 1800s to the present day, by the USGS, the State Geological Surveys, and hundreds of other organizations.
