Statement

Data were collected using a direct shear setup, where layers of quartz gouge were sheared in a triaxial deformation apparatus. In the direct shear geometry the normal stress is applied by the confining pressure (Pc), and pore fluid pressure (Pf) is introduced to the sample through the three porous disks on each of the direct shear forcing blocks. Deionized water was used as the pore fluid, which was held at a constant pressure of 20 MPa for all experiments in this study. The samples are sheared by the axial piston of the triaxial apparatus at a constant displacement rate of 1 µm/s. The evolution of shear stress is monitored by an internal force gauge, with a measurement resolution better than 0.05 kN, while the effective normal stress (=Pc-Pf) is held constant by servo-controlled pumps, with a resolution better than 0.1 MPa, on both the confining and pore pressure systems.
