Abstract: Aaccording to the study on oil一gas source rocks in China for ten years, at the microscopic and submicroscnpic levels,the authors on the one hand used the microscope photometry together with transmission electronic; microscopya nningelextronic miroscnpy, Fourier transformation infrared microscopy and sexondary ion mass spectrometry to study the petro-logical and geochemical characteristics of organic matter and on the other hand employed small tubes and the pressure cnok-er for thermal simulation, cxmbined with analyses of organic; petrology and geochemistry to elaborate their hydrocarbon-generating regularities. On the basis of these studies, the authors proposed a new classification for sedimentary organicnlatter. This classification is notoy suitable for terrestrial source rocks, but also for marine ones, meanwhile, the influenceof maturity on macec;als is cxmsidered, and the division of source mac;erals was modified. The characteristic of the composition or structure of some macerals such as zoo-organite and amorphonite are deter-mined espeeially the oil-genecating models of both maceraLs in Chinese source rocks and individual marine organisms wereset up.
