应用现代有机岩石学与有机地球化学相结合的方法，通过对我国海相烃源岩的研究，确认了一种新的显微组分——海相镜质体。这种显微组分源于动物有机质，在还原—强还原条件下，经强烈生物降解作用形成。人工热模拟实验表明，海相镜质体成烃较晚，主成油期在镜质组Ｒｒ１．０％～１．３０％范围内，产油率高达６％～８％，并以气态烃为主。海相镜质体反射率在高成熟阶段后可作为良好的成熟度作用指标
By means of combining modern organic petrology and organic geochemistry, a new microscopic component, sea-phase vitrinite, has been confirmed through the study of marine source rocks in China. This micro-component from animal organic matter, in the reduction - strong reduction conditions, the role of strong biodegradation formed. Artificial thermal simulation experiments show that the vitrification of the marine vitrinite is relatively late. During the main oil-formation period, the oil-producing rate is as high as 6% -8% in the vitrinite Rr1.0% -1.30% Mainly. The vitrinite reflectance of marine phase can be used as a good indicator of maturity after high maturity stage
