Whole-rock chemistry of Hole G core samples from the San Andreas Fault Observatory at Depth (SAFOD), California

We present whole-rock geochemical analyses of 27 Phase 3 core samples obtained from Hole G of the San Andreas Fault Observatory at Depth, which crosses the creeping section of the San Andreas Fault ~14 km NW of Parkfield, California. These new data will essentially double the published whole-rock chemical dataset for the SAFOD Hole G core. Two, meters-wide zones of foliated gouge where fault creep is concentrated were successfully cored in Hole G. The gouge zones are bounded on either side by variably deformed structural units of sedimentary rock. Sampling for this dataset was focused on the gouge-wall rock boundaries and meters-long sections of the wall rocks that previously lacked chemical data. Major, trace, and rare-earth element data were obtained for each analyzed core sample at the GeoAnalytical Lab of Washington State University, Pullman, Washington.
