Alkalic Igneous Centers of the Great Plains and Rocky Mountains: Data in Support of Critical Mineral Resource Studies

This community is designed to link data acquired for alkalic igneous centers of the western United States in support of critical mineral resource investigations. Areas of interest include, but are not limited to, the Central Montana Alkalic Province, Northern Black Hills (South Dakota-Wyoming), Front Range of Colorado, and Great Plains margin in New Mexico and Texas. Datasets may include, but are not limited to, geochemical, geochronological, and isotopic data. Scientists interested in contributing to this community are asked to contact the manager(s).

Carbonatite whole-rock and calcite geochemistry from the Bear Lodge alkaline complex, Wyoming and Mountain Pass mine, California

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...
