| 摘 要： | 对塔里木、鄂尔多期和华北东部寒武－奥陶系碳酸盐岩和泥页岩全岩和干酪根样品进行了有机岩石学分析，确认出其中普遍存在镜状体，根据对爱沙尼亚奥陶系库克油页岩不同温度下加水热解系列样品残渣的镜检分析比较，提出下古生界高过成熟烃源岩中镜状体主要来源于藻类体的热解残留物，它是下古生界高过成熟烃源岩的主要有机显微组分，镜状体反射率可作为良好有机成熟度指标。

| Abstract: | Vitrinite-like macerals existed widespreadly in high-postmatureCambrian-OrdoviCian carbonate and shale source rocks in China,according to a thoroughorganic petrological analysis of whole rocks and kerogen concentrates.Comparisons withimmature Estonian kukersite subjected to hydrous pyrolysis indicated that vitrinite-likemacerals originated from the autochthonous residues of algae thermal degradation,especiallyfrom Gloeocapsomorpha prisca which were the main contributor to the organic matter of theearly palaeozoic source rocks.The reflectance of vitrinite-like macerals can be used as asuitable thermal maturity index of early palaeozoic source rocks.The proper stage of vitrinitereflectance range from 1.0% to 2.0%. |
