GIS and Data Tables for Focus Areas for Potential Domestic Nonfuel Sources of Rare Earth Elements

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...

Geochemical characterization of solid media from three watersheds that transect the basal contact of the Duluth Complex, northeastern Minnesota

To document regional water quality in areas of potential base-metal mining, bedrock, soil, streambed sediment, and surface-water samples were collected and analyzed in three watersheds that cross the basal part of the Duluth Complex (northeastern Minnesota). The three watershed each had different mineral-deposit settings: (1) copper-nickel-platinum group element mineralization (Filson Creek...

Exposed Precambrian Bedrock in Part of Dickinson County, Michigan, and Marinette and Florence Counties, Wisconsin

The U.S. Geological Survey conducted a program of bedrock geologic mapping in much of the central and western upper peninsula of Michigan and parts of Wisconsin from the 1940’s until the late 1990’s. Geologic studies in this region are hampered by a scarcity of bedrock exposures because of a nearly continuous blanket of unconsolidated sediments resulting from glaciation of...

X-ray diffraction data from the Ironwood Iron-Formation, Gogebic Iron Range, Wisconsin, USA (ver. 2.0, April 2019)

This worksheet displays the results of X-ray diffraction (XRD) analyses of samples from the Ironwood Iron-Formation. Samples were analyzed using a PANalytical X'Pert Pro diffractometer using Co radiation and the results interpreted using Highscore Plus v.4.5. Mineral abundances were determined by Rietveld refinement.

Global distribution of selected mines, deposits, and districts of critical minerals

Approximate locations and short descriptions of mines, deposits, and districts where critical minerals are found. The critical minerals are discussed in USGS Professional Paper 1802, and many of these locations are described in further detail in that report.

Geochemical Database for Iron Oxide-Copper-Cobalt-Gold-Rare Earth Element Deposits of Southeast Missouri

The Geochemical Database for Iron Oxide-Copper-Cobalt-Gold-Rare Earth Element Deposits of Southeast Missouri (IOCG-REE_GX) contains new geochemical data compilations for samples from IOCG-REE type deposits in which each rock sample has one "best value" determination for each analyzed species, greatly improving speed and efficiency of use. IOCG-REE_GX was created and designed to compile whole-...

Global Distribution of Selected Mines, Deposits, and Districts of Critical Minerals

The point and polygon layers within this geodatabase present the global distribution of selected mineral resource features (deposits, mines, districts, mineral regions) for 22 minerals or mineral commodities considered critical to the economy and security of the United States as of 2017. These data complement the report by Schulz and others (2017) which provides national and global...

Locatable Mineral Assessment Tracts for the U.S. Geological Survey Sagebrush Mineral-Resource Assessment Project

The polygon (vector) feature class represents locatable mineral resource assessment tracts (tracts of land) associated with the Department of the Interior (DOI) Sagebrush Focal Areas (SFAs) in Montana, Wyoming and Utah, central Idaho, and the Oregon-Nevada-Idaho border area. The mineral-resources tracts are geographic areas that were assessed by the USGS and were determined to be geologically...

Prospect- and Mine-Related Features from U.S. Geological Survey 7.5- and 15-Minute Topographic Quadrangle Maps of the Western United States

These data are part of a larger USGS project to develop an updated geospatial database of mines, mineral deposits and mineral regions in the United States. Mine and prospect-related symbols, such as those used to represent prospect pits, mines, adits, dumps, tailings, etc., hereafter referred to as “mine” symbols or features, are currently being digitized on a state-by-...

Bureau of Land Management's Land and Mineral Legacy Rehost System (LR2000) mineral use cases for the Sagebrush Mineral-Resource Assessment, Idaho, Montana, Nevada, Oregon, Utah, and Wyoming

In 2015, approximately 10 million acres of Federal lands across six western states were proposed for withdrawal from mineral entry by the Bureau of Land Management (BLM) in order to conserve habitat critical for the greater sage-grouse. As a result, the U.S. Geological Survey (USGS) launched the Sagebrush Mineral-Resource Assessment (SaMiRA) project in late-2015 to provide BLM with an...

Geochemical and Mineralogical Maps for Soil for the Conterminous U.S.

Online data set provides an estimate of the abundance and spatial distribution of chemical elements and minerals in soils of the conterminous United States and represents a baseline for soil geochemistry and mineralogy against which future changes may be recognized and quantified.
