摘　　要：高等植物分泌的含松香酸类物质的树脂在成岩作用下形成惹烯，已是有机地球化学的常识；但藻类等低等生物可否形成惹烯却未被证实。本文通过对岩石薄片和干酪根的扫描电镜观察，结合岩石抽提物芳烃馏分和干酪根热解产物的色质分析资料，证实了下扬子准地台震旦系和下古生界无高等植物输入的海相碳酸盐地层中也生成了丰富的慧烯化合物，且其前身物同样是松香酸类物质。Resin derived from abietic acid containing matter secreted from high plants to form retenes under diagenesis is a well-known geochemical fact. However,whether retenes can be derived from lower organisms, such as algae is not confirmed so far. By an examination thin section of rock samples, and SEM decription of kerogen samples, as well as a geochemical study of the results of analysis of aromatics fraction from rock samples and the thermolysis products from kerogens confirms that there are abundant retene compounds from Sinian and Low Paleozoic formations in Lower Yantze Platform which does not contain higher plants. Moreover, their precursors are abietic acid meterials also.
