Abstract
Velocity profiles and shear heat profiles for inclined layered Newtonian simple shear zones are considered Reverse faultlike simple shear of the boundaries and upward net pressure gradient act together in such shear zones As the velocity of the boundary increases the point of highest velocity shifts from the lower layer of less viscosity into the upper layer The shear heat profile shows a temperature peak inside the lower layer For a more viscous upper layer the point of highest velocity is located inside the upper layer and shifts towards the upper boundary of the shear zone The shear heat profile shows a maximum temperature within the upper layer Depending on the flow parameters of the two layers the slip rate of the boundary and the dip and thickness of the shear zone a shear sense in reverse to the relative movement of the shear zone boundaries may develop These models can decipher thermokinematics of layered shear zones in platescale hot orogensDepartment of Science and Technology’s New Delhi satellite project IR/S4/ESF16/2009G supported SM Thanks to two anonymous reviewers for critical comments Eugenio Carminati for editorial handling and reviewing Rakesh Biswas for discussions and Priyanka Ganesh for assistance
