Abstract: It is not appropriate to assume constant frictional stress and constant slip velocity for calculating temperature rise on fault during stick slip. Neither could the fault thickness be simply neglected. In most cases, frictional stress depends on rock and interstitial fluid properties. Five models of frictional heating are considered in this paper for various fault thickness, frictional stress and slip velocity which vary with time. The result shows that temperature rise is lower than those calculated by assuming constant frictional stress, constant slip velocity or zero fault thickness. This conclusion will remind scientists to pay attention to the result precise of TL and ESR dating.
