Neotectonic Evidences of Rejuvenation in KaurikChango Fault Zone, Northwestern Himalaya

Neotectonic investigations using morphotectonic parameters such as basin asymmetry, drainage anomalies, digital data interpretation and geomorphic field evidences were carried out in Satluj river valley downstream of Khab in the Kaurik Chango Fault (KCF) zone. The study reveals the presence of a north-south trending fault which is similar to the KCF. Unpaired, tilted terraces, V shaped valleys, deep gorges and lakes are the manifestations of fault movement in the area. Presence of deformation structures preserved in the palaeolake profile at Morang indicates that the area has also been seismically active in the past. In this paper we present a conceptual model of the formation of lakes in KCF zone. Morphometric analysis was carried out with the help of Digital Elevation Models (DEMs) and field investigations.
