Geomorphology of the Anabal-Udzha interstream area

Abstract

Detailed geomorphological study has shown that drainage network of the 'region had at least one basic alteration during Cenozoic period. Widespread areal prevalence of denudation planation surfaces was revealed: within the altitudinal range 125-290 m there are more than ten such surfaces but not one or two as it was considered earlier. On the less than 200 m levels there are extant covers of subaerial loose deposits, that-serve as intermediate collectors of kimberlitic minerals.
