Data recorded during triaxial rock deformation experiments of Westerly granite in the presence of pressurised pore fluids (water). Data consists of mechanical data (load, displacement, confining pressure) and pore pressure data (up- and downstream pore pressure, upstream intensifier volume, four pore pressure transducers mounted on sample) for two experiments, recorded at low and high acquisition frequencies. Also contains .h5 files with all ultrasonic waveforms (active surveys and acoustic emissions). Dataset complementary to dataset ID165485 . Contains all data necessary to evaluate the results presented in the paper entitled: 'Rupture and afterslip controlled by spontaneous local fluid flow in crustal rock' by Aben and Brantut, submitted to Geophysical Research Letters, and available at arXiv (arXiv:).

Geochemical and petrophysical data acquired on intact and damage zone rock samples for two localities along the San Andreas Fault, Mojave section. 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. 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.
