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...

The National Elevation Dataset (NED) is the primary elevation data product of the USGS. The NED is a seamless dataset with the best available raster elevation data of the conterminous United States, Alaska, Hawaii, and territorial islands. The NED is updated on a nominal two month cycle to integrate newly available, improved elevation source data. All NED data are public domain. The NED is derived from diverse source data that are processed to a common coordinate system and unit of vertical measure. NED data are distributed in geographic coordinates in units of decimal degrees, and in conformance with the North American Datum of 1983 (NAD 83). All elevation values are in meters and, over the conterminous United...
