Development of extension faults on the oblique thrust ramp hanging wall: example from the Tethys Himalaya

Inhomogeneous strain at late stages of deformation of modelling clay models with frontal and oblique thrust ramp geometries results in formation of extension faults on the hanging wall. The extension faults trend nearly parallel to the axis of maximum compression and orthogonal to the trend of the frontal ramp. Faults with similar geometries occur in the Upper Satluj River Basin of the Tethys Himachal Himalaya. The experimental results help in understanding the present day normal faulting and related active tectonics of the area. [Copyright &y& Elsevier]
