Classification of volcanic slopes of Armenia and some of their special features

Abstract

The division of volcanic slopes of Armenia on morphological indication and origin, material composition, profile form and length is given. The volcanic slopes are formed very quickly («instantly»), they lack loose material for some time and well preserve their original form. The conclusion is drawn that the downwearing process is typical for volcanic slopes of Armenia. Parallel retreat can manifest only temporarily in vertical scarps of volcanic plateaus, necks, lava flows, in case of vertical columnar jointing and it is typical for early stage of their evolution. It can proceed longer if the debris is removed from the foot of slope quickly.
