Petrographic composition of organic matter of Permian terrigenuos deposits (Kosyu-Rogov depression)

The results of study of heterogeneous composition of organic matter of Permian terrigenous deposits, characterized by various generation possibilities, have been presented. To estimate further oil-gas generating potential of the deposits under study the petrographic composition of the organic matter was determined, and the following groups of microcomponents were specified: vitrinite, inertinite and liptinite. The predominance of mixed organic matter with liptinite group content more than 5% was determined in the rocks.
