Earth Mapping Resources Initiative (Earth MRI)

Project Details

---

• Project ID:

  1597

• Nickname/Abbreviation:

  Earth MRI

• Parent Project:

  Mineral Resources Section projects

• Status:

  Active

• Description:

  The Earth Mapping Resources Initiative (Earth MRI; formerly known as 3DEEP) is planned as a partnership between the U.S. Geological Survey (USGS), the Association of American State Geologists (AASG), and other Federal, State, and private-sector organizations. The goal of the effort is to improve our knowledge of the geologic framework in the United States and to identify areas that have the potential to contain undiscovered critical mineral resources. Enhancement of our domestic mineral supply will decrease our reliance on foreign sources of minerals that are fundamental to the Nation's security and economy.
