Role of Cross Faults in Himalayan Tectonics.pdf

There has been increasing field evidence for the presence of cross faults across the Himalaya. A number of these structures have been recognized at strike changes of the Main Frontal Thrust, but there is also evidence in the Greater Himalayan sequence for cross faults or transverse shear zones. Interestingly, there are also features from the seismic record that suggest that cross structures may concentrate some seismicity and that cross structures may limit the lateral propagation of thrust ruptures. A number of these structures align with structures on the Indian basement
