Abstract

Faulting is typically a two timescale process, that is, rapid failure and slow (chemical) healing. Once failed, a rock has a long memory until slow chemical processes have time to re-establish the grain-grain contacts underlying rock competency, The memory of rock failure can be captured by a sufficiently rich textural model, and the texture must be coevolved with rock stress and deformation to yield a self-consistent model of strain hardening/weakening, fault narrowing, and earthquake cyclicity.
