Altitudinal zonality of slope processes in the Armenian Highland and special features of slope evolution

Abstract

Slope processes and their manifestations are discussed which are typical of various orographic zones. A loose material mantle on slopes is rather thin, which the author attributes to the young age of the slopes and to the fact that products of weathering are continuously removed from steep slopes by mud and debris flows. On many lava slopes (especially on those composed of block lavas) the loose mantle is now at initial stages of development, the process being hindered by a relative aridity of the region.
