脆性断裂剪切加热在石油地球科学、构造学和地震学研究中具有重要意义。本文研究了旋转断层和旋转平移断层的剪切热温升随时间的变化。对于没有断层泥和任何次级断层的平面断层面，温升与摩擦系数和（角）滑动速率成正比。旋转断层，特别是延长断层的构造现实物理参数，可以显着提高温度的剪切加热在地壳浅部，能够热成熟的烃类。
Brittle faulting-related shear heating is important in petroleum geosciences, tectonics and seismic studies. Temporal variation of shear heat related temperature rise for rotational and roto-translational faults are investigated in this work. For planar fault planes, devoid of gouge and any secondary faulting, temperature rise is proportional to the coefficient of friction, and rate of (angular) slip. Tectonically realistic physical parameters for rotational faults, especially prolonged faulting, can significantly increase temperature by shear heating at shallow crustal depth, capable of thermal maturity of hydrocarbons.
