Description
These data encompass data classified from the borehole textures. The U.S Geological Survey (USGS) classified the Well Log Database of the Central Valley, California, 2021, into Central_Valley_Borehole_with_Lithology_Classification.csv. Lithologic log descriptions served as the basis for division into discrete binary texture classifications of either “coarse grained” or “fine grained” intervals. Values of 1 (coarse grained), 0 (fine grained) or 2 (unknown) were determined using the table found in Central_Valley_Lithology_Classifier.csv. Percent Coarse values for each well log were calculated at 15.24 m for the entire Central valley (Percent_Coarse_meters_wells.csv).
