The structure and distribution of the hydrocarbon biomarkers of poorly explored complex of the Middle and Lower Jurassic deposits, south of the Eastern Siberia, have been investigated by modern geochemistry methods. Low-boiling hydrocarbons, ordinary and isoprenoid alkanes, sterany, turpane, triaromatic sterany and phenanthrene have been identified in the structure of bitumens. The hydrocarbon structure and distribution regularity of different types of the dispersed organic matter have been analyzed. The hydrocarbon biomarkers structure and distribution of catagenesis graduation are shown to be connected with the type of original organic matter, whereas the hydrocarbon biomarkers structure and distribution inside each type of organic matter are connected with the ratio of humus and sapropel components.
Key words: bitumens, dispersed organic matter, argillite, hydrocarbon biomarkers, Eastern Siberia, Middle and Lower Jurassic deposits.
