Abstract: Having investigated the detailed organic petrological characteristics of the marine hydrocarbon source rocks in the Tarim basin, the authors systematically elucidate the optical properties and origins of macerals occurring in these marine source rocks.Four new macerals have first been recognized in the source rocks,which are called as algobitumen, zobitumen, vitrinite-like macerals and marine inertinite. On the basis of this observation, a petrographic classification of macerals of the marine hydrocarbon source rocks in the Tarim basin has been suggested. This scheme is based on the research of the polished surfaces of the whole rocks and the thin sections of kerogen. The influence of maturity level on optical properties of macerals is emphasized in this scheme, so this classification scheme is also suitable to other marine hydrocarbon source rocks.
