Comment on: “Morphotectonic records of neotectonic activity in the vicinity of North Almora Thrust Zone, Central Kumaun Himalaya”, by Kothyari et al. 2017, Geomorphology (285), 272–286

Abstract

The recent paper by Kothyari et al. (2017) suggests that the North Almora Thrust (NAT) and a few subsidiary faults in the central Lesser Himalaya were active during the late Quaternary and Holocene. Considering that in the Indian Summer Monsoon (ISM) dominated and tectonically active central Himalaya, the landscape owes their genesis to a coupling between the tectonics and climate. The present study would have been a good contribution toward improving our understanding on this important topic. Unfortunately, the inferences drawn by the authors are based on inadequate/vague field observations, supported by misquoted references, which reflects their poor understanding of the geomorphic processes. For example, authors implicate tectonics in the landform evolution without providing an argument to negate the role of climate (ISM). In view of this, the above contribution does not add anything substantial in improving our existing knowledge of climate-tectonic interaction in landform evolution. On the contrary, if the above publication is not questioned for its scientific merit, it may create enormous confusion and proliferation of wrong scientific data and inferences.
