Abstract

This region, drained by major river system, represents an ideal environment for fluvial fan and terrace formation. On the basis of analysis of Quaternary landforms the faults that were active during the Late Pleistocene-Holocene were identified. Imprints of active tectonics on the landforms are discernible in the form of tilted fans, colluvial deposits and terraces, truncation of toe of fan, linear fault scarps and thrusting of Siwalik rocks over the colluvial deposits. OSL dates for fans and terrace deposits indicate tectonic activities between 8 and 56 ka. It is showed that geomorphic evidence, chronology of depositional landforms, deformation of Quaternary landforms and soft-sediment deformation structures provide baseline information about neotectonic activity in the region
