On methods of the rock glaciers studies

Abstract

A case study of the «Karakorum» rock glacier is used to show possibilities of lithological methods in revealing conditions of the development of such a landform. The methods permitted to establish asynchroneity in the real glacier and the proglacial «Karakorum» rock glacier evolution, both situated within a valley on a nor hem slope of the Kungei-Alatau Range. Besides, steps in the rock glacier are shown to be formed at different time. Some special features of the landform are explained as resulted from subaerial weathering processes.
