本文主要对中扬子地区海相地层中的生物标志化合物进行研究。目前已检测出的有甾烷、双环倍半萜、三环二萜、四环萜、五环三萜类的藿烷和γ-蜡烷等6类生物标志化合物。综合分析其组成分布与构型演化等待征,较清楚地反映了本区海相地层有机质生活环境、母质类型及演化阶段的面貌。对丰富我国海相领域的有机地球化学特征及深入开展本区的油气研究,有重要的参考价值。

In this paper,the study is mainly focused on biomarkers in the marine esquences ofthe Mid-Yangtz area. At present,the determined six types of biomarkers are sterane,di-cyclosesquiterpene,tricycloditerpene,tetracyclene, horane of a pentacyclotriterpene kind and γ-waxane. By comprehensive analysis on the characters of their composition distribution and evolution of configuration,the biogenic environment of organic matter.the kerogen types and the evolution levels in the marine sequences of local area could be clearlyoutlined.This study has an important reference value for better understanding of the organic geochemical characters of the marine sequences and the further geochemical researchin the area.
