Density and magnetic properties of selected plutons (granitoids) in the Great Basin, parts of Arizona, California, Idaho, Nevada, Oregon, and Utah

The U.S. Geological Survey (USGS) collected over 1,840 physical property measurements on selected plutons in the Great Basin, primarily in California and Nevada. Data include station identifier, geographic coordinates, rock type, density, magnetic susceptibility, remanent magnetization, declination, and inclination where available. Data are presented in ASCII format and include density and magnetic property data in pluton_data.csv, a data dictionary describing the data fields in data_dictionary.csv, and a rock data dictionary listing rock types in rock_dictionary.csv. Preliminary results and interpretation were described by Ponce and others (2010) and some samples are from Sikora and others (1991). References: Ponce,...

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

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.
