A rheologic model for wet crust applied to strike‐slip faults Academic Article uri icon


  • The strength and stability of crustal faults are not adequately addressed by the widely used two-mechanism rheologic models of the crust based on Byerlee's law and power law creep. Several distinct mechanisms of frictional slip are defined on the basis of variations in frictional behavior and microfabric of simulated fault gouge in laboratory experiments. State variable constitutive relations are used in a multiple-mechanism formulation to describe the rate and temperature dependence of three friction mechanisms in wet quartz gouge at elevated temperatures. This multimechanism description of friction is substituted for Byerlee's law in the two mechanism models to generate a multimechanism rheologic model for the crust. -from Author
