Abstract
Abstract Shear heating due to brittle faulting is important in petroleum geosciences, tectonics and seismic studies. Temporal variation of shear heat in a listric normal fault, with a circular arc-shaped fault plane is simulated in this work, which was not done so far. The work is expected to have a far reaching implication in tectonics and petroleum geosciences since listric faults can be closely associated with hydrocarbon reserves (e.g., Valdiya and Sanwal, 2017 ). For such a fault plane devoid of gouge and any secondary faulting, shear heat is proportional to the mass of the hanging-wall block, the coefficient of friction acting between the hanging-wall and the footwall block, and radius of the circular arc. Shear heating intensifies temporally as the hanging wall block slides down and reaches progressively gentler fault dip.
