Gravity and physical property data of the Blythe region, California and Arizona

This data release presents point data associated with studies to understand the crustal structure of the Blythe region, where strands of the pre-Quaternary Eastern California Shear zone project across this region in California and Arizona. Data include principal fact information for new gravity measurements collected by the U.S. Geological Survey from 2020 to 2025, previously unpublished gravity measurements in the 1980s and 1990s, and for existing gravity measurements compiled from 5 sources. More than 3,300 gravity measurements were processed to complete Bouguer and isostatic gravity anomalies to provide information on crustal structure, such as the geometry of Cenozoic basins developed along and between faults. Density and magnetic property measurements were also compiled from older sources and combined with new density and magnetic susceptibility measurements of hand samples in the region. Some magnetic susceptibility measurements are of outcrops within the region.
