... surface experiments we observe that restrengthening depends on both time and temperature. At 200 °C the simulated fractures restrengthen at a rate of Δ μ /Δlog( thold hold ) = 0.009/decade while at 22 °C the healing rate is ~ 0.002/decade. In the gouge experiments restrengthening appears...

... strengthening behavior in velocity up-step experiments but velocity weakening behavior for velocity down-steps. Marcellus has the lowest frictional healing rate of 0.0076 that is lower than that for the 50:50 mixture (0.0116) with quartz the highest (0.0154). The frictional creep rates are in the order...
