This data release contains the whole-rock major and trace element analyses of 51 samples of intrusive igneous rocks from the Wet Mountains area of Custer and Fremont counties of south-central Colorado, collected by U.S. Geological Survey (USGS) geologists. The samples were collected from breccias, veins and thin dikes, and a variety of carbonatite, felsic, mafic, and ultramafic intrusions across the area. The first 41 samples listed in this data release were collected in July 2007, originally as part of a reconnaissance study of the thorium deposits of the area (Van Gosen and others, 2009). The samples are grab samples from outcrops, shallow open-pit excavations, and mineral prospect trenches. The last 10 samples...

This data release contains analytical data from a suite of rock samples collected within the Bear Lodge alkaline complex, northeast Wyoming, which hosts the Bear Lodge rare earth element (REE) deposit. Geochemistry data include major and trace element analytical results for 105 samples including alkaline igneous rocks, carbonatites, and weathered and oxidized samples. Samples were collected from surface exposures, a shallow temporary exploration trench, and drill core. Drill core samples are from exploration holes drilled by Rare Element Resources between 2009 and 2013 and from historical drill core from previous exploration companies. Rare earth element mineralization at Bear Lodge is hosted by carbonatite dikes,...

The U.S. Geological Survey (USGS), Colorado Division of Reclamation, Mining and Safety (DRMS), and Coal Creek Watershed Coalition (CCWC) working independently, have intermittently collected samples of surface- and groundwater and springs around Mount Emmons, near Crested Butte, Colorado. This data release is a compilation of the comprehensive inorganic chemical analyses conducted as a result of that sampling. The earliest samples were collected in the summer of 1997, and subsequent sampling has continued through 2019. Water samples collected in the Elk Creek basin, sample identifiers starting with EC, have been previously published in three U.S. Geological Survey reports; Verplanck and others, 2007, Manning and...
