THE SEDIMENTOGENESIS AND RESERVOIR PROPERTIES OF THE VENDIAN PRODUCTIVE PARFENOVSKY HORIZON OF THE ANGARA-LENA STAGE
A detailed sedimentological study of Parfenovsky Horizon deposits performed on the basis of data obtained during deep drilling in the central part of the Angara-Lena stage. It is shown that sedimentation occurred in conditions of the shelf and advancing coastal alluvial system. The reservoir properties were controlled both with the particle size and primary material composition of rocks, and also with the postsedimentary processes.
