- Abstract:
- The occurrence of suprahydrostatic pore fluid pressures is widely invoked to explain the apparent weakness of large fault zones such as the San Andreas fault. Key questions concern the process whereby high pore pressures can be generated and maintained for long periods without leakage even during shear. Clay-bearing fault zones may provide effective seals, but evaluation of their effectiveness requires experimental studies of their petrophysical properties and the way these vary with pressure, temperature and frictional deformation. We will measure the strength and permeability of synthetic fault rocks of controlled composition, how they evolve with shearing, and evaluate the implications for fault rock strength and stability.
