landforms, we mainly sampled the uplifted side of the GCF and the abandoned western edges of alluvial fans and/or preserved river terrace risers. This approach reduces the possibility that later erosion may influence our results and interpretations. OSL dating was used to study the northern segment of the GCF at the Aerqingsang and Quba sites ( Fig. 1 ). Six samples were collected from the alluvial sediments. To avoid potential exposure to daylight whilst sampling, sediments for equivalent dose ( D e ) determination were only taken from the middle part of each steel

Sampling and laboratory procedures Sampling sites Samples were collected from two sites in Manas Lake (sites 1 and 3 on Fig. 2 ). OSL samples were taken either by hammering stainless steel tubes (30-cm long with 5-cm diameter) into an exposed sedimentary section (site 1), or by taking block samples (site 3). Both ends of the tubes were then sealed immediately with tissue papers and tapes to avoid any exposure to light or loss of moisture content. For block samples, they were sealed in plastic bags and were wrapped with tapes to avoid breakage during transport

) The study region lies in the northern part of West Bengal, India. (b) The figure shows the tectonic division of the Himalayas and the present study area, (c) The figure shows the major geomorphic features in the study area. The sampling sites are marked with red star. The northern most fault known as Gorubathan is marked by black line just below the Samsing surface. The two other E-W scarps/faults viz. Matiali and Chalsa are also shown in the figure. The NNE-SSW and nearly N-S scarps along which the Murti and Neora rivers flow respectively are also shown in the
