Descriptions

Geochemical and petrophysical data acquired on intact and damage zone rock samples for two localities along the San Andreas Fault, Mojave section. Rock samples (33 samples at Lake Hughes locality, 27 at Littlerock locality) were analysed for porosity, grain- and bulk density, and chemical composition (XRF analysis). Mineral content was established from point counting on thin sections for 9 samples (Littlerock locality) and 13 samples (Lake Hughes locality). The results of these analyses are presented in this dataset. In addition, the samples were grouped in three categories: intact, damaged, and pulverized. Statistical analysis was performed on the grouped data to identify statistically significant changes between the groups. The statistical analysis results are presented here as well. Data used in the publication entitled "Chemically altered Pulverized granite along the Mojave section of the SAF shows evidence for large-scale heat transfer by post-seismic fluid flow and fluid overpressure at depth" by F.M Aben et al., in revision at the journal Geochemistry, Geophysics, Geosystems.
