A Petrographic Classification and Organic Petrological Characteristics of Macerals of the Marine Hydrocarbon Source Rocks in the Tarim Basin
-
摘要: 通过对塔里木盆地海相烃源岩所作的详细有机岩石学研究,提出了适合该盆地的以全岩及干酪根为基础的海相烃源岩显微组分分类方案,系统地阐述了各显微组分光性、成因及岩石学特征。在该盆地早古生代源岩中发现了藻类型沥青、动物型沥青、镜状体及海相惰性体等几种显微组分。该分类方案考虑了成熟度的影响,因此也适用于其它地区海相烃源岩。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.
