| 摘 要： | 本文对多年来积累的江苏下扬子区寒武系－三叠系牙形刺CAI材料进行了系统收集和整理，并采用Anita Harris建立的统一标准，编制了本区寒武系－三叠系的5幅牙形刺CAI图；进而结合牙形刺CAI与镜质组反射率（Ro)的对应关系，对上述各系的有机质成熟度进行了评价，对本区海相中、古生界油气勘探具有十分重要的意义。

| Abstract: | A database of conodont CAI values from Cambrian to Triassic, Lower Yangtze Region in Jiangsu, E China, has been accumulated over many years. Based on their systematic collection and collation and Harris's theory of CAI standards, 5 conodont CAI maps are compiled and discussed in this paper. The organic maturities of Cambrian through Triassic are evaluated according to the correlation of conodont CAI with vitrinite reflectance (Ro). The significance of this study is that it will benefit oil and gas exploration from marine facies of Paleozoic and Mesozoic Units in this area. |
