Abstract: | The terraced gravel deposits of the Baglung-Behadi region in the Kali Gandaki valley, central West Nepal, reveal geomorphic features related to neotectonism. The accumulation of thick fluvioglacial gravel deposits in lake-like basins along the then existing river course took place due to the uplift of the southern Mahabharat Range and the relative subsidence of the Midland. The deposits consist of unsorted fragments of variable size, showing considerable uniformity laterally over large areas from north to south, and with abundant angular to sub-rounded boulders of Dhaulagiri limestone and gneisses of the Main Central Crystallines. Terrace flats arranged in three successive levels on either side of Kali Gandaki show that the region has undergone at least three periods of uplift. |
