This development of the dataset was funded by the U.S. Geological Survey Mineral Resources Program (MRP). The data sets were developed by 4 regional teams within the U.S. Geological Survey: Eastern Mineral and Environmental Resources Science Center (Reston, VA); Geology, Geophysics, and Geochemistry Science Center (Denver, CO); Geology, Minerals, Energy, and Geophysics Science Center (Spokane, WA and Tucson, AZ); and Alaska Science Center - Geology Office (Anchorage, AK). Database reviews and contributions were made by USGS personnel John C. Wallis and Philip Verplank. |

<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>In response to Executive Order 13817 of December 20, 2017, the U.S. Geological Survey (USGS) coordinated with the Bureau of Land Management (BLM) to identify 35 nonfuel minerals or mineral materials considered critical to the economic and national security of the United States (U.S.). Acquiring information on possible domestic sources of these critical minerals is the basis of the USGS Earth Mapping Resources Initiative (Earth MRI). The program, which partners the USGS with State Geological Surveys, federal agencies, and the private sector, aims to collect new geological, geophysical, and topographic (lidar) data in key areas of the U.S. to stimulate mineral exploration and production of critical minerals. The first phase of Earth MRI focuses on the study of rare-earth elements (REE). The USGS has identified broad areas within the U.S. to target acquisition of geologic mapping, geophysical data, and (or) detailed topographic information to aid research, mineral exploration, and evaluation of REE potential in these areas. Focus areas were defined using existing geologic data on known REE deposits in the U.S. Focus areas were then prioritized and ranked by the Earth MRI team.</SPAN></P><DIV><DIV><P><SPAN>Priority areas delineated by the Earth MRI team are not published, but are included in this geodatabase or internal USGS use only. The focus areas are provided in a GIS data release as geospatial data supported by tables that summarize what is known about the REE potential and brief descriptions of data gaps that could be addressed by the Earth MRI program (https://doi.org/10.5066/P95CHIL0). A full discussion of Earth MRI and the rationale and methods used to develop the geospatial data are provided in the accompanying USGS Open-File Report (https://doi.org/10.3133/ofr20191023A). An overview of the Earth MRI effort is presented in the USGS Fact Sheet 2019–3007 (https://doi.org/10.3133/fs20193007). </SPAN></P></DIV></DIV></DIV></DIV></DIV> |
