Description :
The aim of this study is to present geomorphic evidence of neotectonic activity along the mountain front and within the Lesser Himalaya and to reveal the pattern of neotectonic movement in view of orogenic development. High-resolution satellite data have been used to study the geological, geomorphological and tectonic setting of the area. The results suggest the presence of a highly mature, almost flat Brahmaputra floodplain evolved during the recent geological past, in which palaeochannels had a very high sinuosity. Subsequent events of uplift resulted in the formation of entrenched meanders due to incision of the valley floor. The data suggest that tectonic activity along the Main Boundary Thrust (MBT) and Himalayan Frontal Thrust (HFT) during the Holocene have played significant role in geomorphic evolution.
