摘要
本文详细总结了华北地区下古生界海相烃源岩中芳烃生物标志物特征，主要包括菲系列、联苯系列、苯并芴系列，三芴系列、荧蒽系列、芘系列、苯并荧蒽和苯并芘系列、 系列和三芳甾烷系列，而萘系列含量较低。我们发现三芳甾烷C(28)（20S）／C(28)（20R）比值似乎显示了较好的热演化特征。
Presented in this study are the characteristics of aromatic hydrocarbon biomarkers in the Lower Palaeozoic marine carbonate rocks in North China, including phenanthrene, biphengl, benznuorene,benzfhiore tri-fluorene, fluoranthene series pyrene, benz fluoranthene series beamperylene, chrysene and triaromatic sterane. The content of naphthalene is relatively low. It is found that C(28)(20S)/C(28)(20R) ratio in triaromatic sterane seems to show good thermal evolution characteristics.
