Rock pulverization at high strain rate near the San

We focused on dynamic pulverization to explain pulverization near faults. Other mechanisms may inhibit the strain localization process. The first one is the ductile-fragile transition at high confining stress or high temperature16. But this transition is too high (300 MPa, 350C16) for crystalline rocks at the ground surface.
