MINERALOGICAL FEATURES OF SEDIMENTOGENESIS IN THE ANGARA RESERVOIRS

Abstract

The composition of the material from provenances and its changes under the influence of transportation and redistribution are reflected in the lithology of bottom sediments both in natural water bodies and in manmade reservoirs. A great body of interesting data on the mineralogy of sediments in natural water bodies has been collected and analyzed to date. Unfortunately, data on the formation of the mineral assemblage in man-made reservoirs are practically unavailable.
