This data release presents point data associated with the geologic and geophysical maps of the Stockton 30 x 60 minute quadrangle, California. Data include principal fact information for new gravity measurements collected by the U.S. Geological Survey from 2015 to 2018 and for existing gravity data. Gravity and magnetic gradients were also calculated in the Stockton 30 x 60 minute quadrangle, California. The gravity data have been processed to isostatic residual gravity anomalies that reflect crustal density variations. Maximum horizontal gradients were calculated from gravity and magnetic potential grids of the Stockton quadrangle to map out structures that juxtapose rocks of differing density and magnetization, respectively.
