Whole Rock Density, Magnetic Susceptibility, and Radiometric Measurements of a Rare Earth Element Terrane, Southeastern Mojave Desert, California and Nevada

Published by U.S. Geological Survey | Department of the Interior | Metadata Last Checked: January 27, 2026 | Last Modified: 2020-08-20T00:00:00Z
Efforts by the USGS to characterize regional geology of the southeastern Mojave Desert near Mountain Pass, California, include 1,061 rock samples collected along the southern California/Nevada border. Rock property measurements include density, magnetic susceptibility, and radiometric concentrations to understand structural and geophysical relationships associated with rare earth element mineral deposits. Notable rock types sampled include, but are not limited to, carbonatite, dolomite, gneiss, granite, granodiorite, limestone, quartzite, sandstone, shonkinite, syenite, and volcanic rocks spanning the study area.
