Gravity and physical property data, basin depth of the Hayfork graben, and horizontal gradient maxima of the southern Klamath Mountains, California

This data release contains principal facts of gravity measurements collected by the U.S. Geological Survey in 2013-2022, a compilation of existing and new density and magnetic susceptibility data, horizontal gradient maxima derived from gravity and magnetic potential fields, and depth of Cenozoic basin fill in the Hayfork basin from inversion of gravity data of the southern Klamath Mountains, California. These data support modeling of gravity and magnetic anomalies to understand the structure beneath the southern Klamath Mountains..

Gravity, density, and magnetic property measurements of the Sierra Nevada, California and Nevada

This data release presents point data associated with the geologic and geophysical maps of the Sierra Nevada Digital Earth Science Atlas led by the California Geological Survey and U.S. Geological Survey. Data include principal fact information for new gravity measurements collected by the U.S. Geological Survey from 2012 to 2023 and for existing gravity measurements compiled from 21 sources. Nearly 29,000 gravity measurements were processed to complete Bouguer and isostatic gravity anomalies to provide information on crustal structure, such as depth extent of plutons and arc terranes, and geometry of Cenozoic basins developed along the margins of the Sierra Nevada. Density and magnetic property measurements were...
