Frictional Behavior of Natural Granite Gouges at Hydrothermal Conditions With Varied Initial Grain Size

Abstract Fine‐grained gouge found in fault cores controls earthquake generation through its frictional behavior and microstructural evolution. Here we present friction experiments on natural granitic gouges of various initial grain sizes at hydrothermal conditions. To obtain the velocity(V)‐dependen...
