Dynamics of landforms evolution in the Makalu – Barun

Year, pages: 2007, 85 - 106

The results of geomorphological analysis of landform patterns in the Makalu – Barun region of the Nepal Himalaya related to morphotectonic features of relief-building processes are presented. High-mountain landforms in the relief section between Mount Everest (8 848 m), Makalu (8 475 m) and the Arun valley (1 350 m) are the result of morphotectonic processes, as well as of denudation and erosional efficiency in different paleoclimatic conditions during the late Cenozoic. Observations in the East Nepal Himalaya also suggest significant feedbacks between the rate of tectonic exhumation of deep crystalline rocks and the intensity of climate-morphogenetic processes. It is suggested that the very high rate of valley incisions also stimulates isostatic compensation, which is one of the factors influencing the uplift of the East Nepal Himalaya during the Quaternary. Extreme exhumation of deep crystalline rocks in the Himalaya during the late Cenozoic is the result of morphotectonic processes, as well as the effective tuning of paleogeographical changes to the extension of the main climate-morphogenetic zones.
