This grant will continue studies of the geometry of fault gouge                 to explore the role of the particle distribution in the                         micromechanics of fault-zone instabilities.  Previous friction                  data will be analyzed in an attempt to correlate the evolution of               frictional parameters such as characteristic displacement and                   velocity weakening with comminution and the evolution of shear                  structures both within the gouge and at the wall-rock interface.                These data will be supplemented by a second series of friction                  experiments, and detailed mapping of natural fault zones to                     search for analogous structures.
