Abstract: The curves showing the change of residual thermoluminescent density of quartz and calcite with temperature at confining pressures of 100 MPa and 30 MPa, respectively, are established from the results of experiments under high temperature and pressure. According to the curves, the effect of frictional sliding under the corresponding confining pressures and at different sliding rates on residual thermoluminescent density of quartz and calcite and related temperature change are studied by means of triaxial frictional experiments and thermoluminescent measurements. Based on the result and the existing theory, the applicability of thermoluminescent method to dating the faulting and to determining the sliding mode along the fault is discussed.
