Heterogeneous valleys of mountain-glacier regions and the origin of cut-off lobes

Abstract

Pre-Upper Pleistocene outwash plains occur in the valleys of mountain-glacier regions, their morphological features are described. The structure of sediment masses of different genesis is under consideration. Morphological and lithological characteristics prove the existence of ancient mountain-valley glaciers here. The cut-off lobes of different morphology appear to be ancient rock bars, and thence constitute a new genetic type of cut-off lobes - glacial type.
