Ribbed and cellular ground moraines of the Eastern Pamir and the Gorny Altai mountains

Abstract

Within some depressions in the Eastern Pamir and Gorny Altai Mountains at 1200-3800 meters a.s.l. for the first time ground moraines have been found (mostly of Middle Pleistocene) characterized with peculiar small-ridge topography. They are similar to ribbed and cellular moraines which belong (according to Yu. A. Lavrushin's classification) to scaly ground moraines faces formed under conditions of ice shift along internal shear planes, Study of the moraines at the ancient mountain glaciation areas is important for glacial deposits identification and reconstruction of paleo-glaciations.
