Laboratory slide-hold-slide tests, combined with flow through tests, conducted on Westerly granite with 30 degree sawcut. Tests were conducted with a constant confining pressure of 30 MPa with an average pore pressure of 10 MPa at temperatures of 23 and 200 degC. Three fluid flow conditions were examined (1) no flow, (2) cycled flow, and (3) continuous flow.

Laboratory flow-through tests were conducted during slide-hold-slide experiments in a conventional triaxial deformation configuration. Experiments were conducted on 1-inch diameter cylindrical cores of Westerly granite bisected by a sawcut oriented at 30 degrees from vertical. Tests were conducted at a constant confining pressure of 30 MPa with a 10 MPa pore fluid pressure. The pore fluid was deionized water. Experiments were conducted at temperatures of 22, 100, and 200 degC.

Laboratory slide-hold-slide tests were conducted in a conventional triaxial deformation configuration on 3/4-inch diameter cylindrical cores of Eureka quartzite bisected by a sawcut oriented at 30 degrees from vertical. Tests were conducted at constant normal stresses of 30, 110, and 210 MPa with a 10 MPa pore fluid pressure. The pore fluid was deionized water. Experiments were conducted at temperatures of 22, 100, and 200 degC.
