Little known organic rocks of sapropelic origin from East Siberia and the Arctic have been investigated; these caustobioliths are characterized by a high degree of maturation. The content of organic solvent-soluble compounds (bitumens) in the organic matter of the shales is determined by the competitive processes of their formation and emigration. Differences between the composition of bitumen and semicoking oil diminish with increasing maturity of the shale. In the bitumens of the highly transformed shales investigated little altered compounds of biological origin were identified. It is probable that the bulk of these bitumens has been formed later, after the high-temperature stage, a result of microbial activity on the basis of kerogen as substrate and other hypergenetic factors. With increasing degree of shale thermal transformation of the hydrocarbon part of its semicoking oil and gas becomes more saturated.
