The geochemical data included here were generated as part of a Technical Assistance Agreement between the U.S. Geological Survey (USGS) and Rio Tinto Exploration based in Salt Lake City, Utah. Beginning in November of 2015, we began a project to reanalyze up to 60,000 archived sample splits originally collected as part of the National Uranium Resource Evaluation (NURE) Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) project from selected areas in Arizona, California, Idaho, Montana, Nevada, New Mexico, and Utah. A small amount (approximately 0.25 g) of sieved <75 micron sample material was retrieved from the USGS National Geochemical Sample Archive for geochemical analysis. These samples were analyzed...

Whole-rock and calcite geochemical data are reported for twelve carbonatite samples collected from the Bear Lodge alkaline complex, Wyoming and from the Mountain Pass mine, California. Calcite geochemical data was collected using electron microprobe and laser ablation inductively coupled plasma-mass spectrometry (LA-ICP-MS) analyses. Reported whole-rock data was measured by inductively coupled plasma-optical emission spectrometry (ICP-OES), inductively coupled plasma-mass spectrometry (ICP-MS), ion selective electrode-fluoride (ISE-F), and wavelength dispersive X-ray fluorescence (WDXRF). Geochemical data are presented in downloadable .csv files. Spatial data of sample collection sites are provided as polygons in...
