Main features of the recent alluvial morpholithogenesis at mountains of the North-East of the USSR

Abstract

Colluvial (slope) morpholithogenesis at the North-East of the USSR includes broad variety of slope proceses (about 20). According to the altitudinal zonality they form a special spectrum at each mountain belt. Slope processes are proved to depend on parent rocks composition. Special features are noted at each of mountain country under discussion (Chersky Range, Kolyma, Priokhotye). A genetic clasification of slope processes is introduced, which is based on differences in their mechanisms, the latter depending on composition, physical properties and consistency of loose slope (alluvial) deposits.
