| 摘 要： | 通过对我国东部盆地洪泽凹陷和临清坳限德州凹陷第三系相沉积泥岩中生物标志物分析，检测到了丰富的甲藻甾烷异构体和２４－正丙基胆甾烷。结合它们的分布特征与产出的地层微体古生物资料，笔者推断它们可能是海侵作用的产物。

| Abstract: | The source rocks and crude oil of the Hongze sag, North Jiangsu basin, and the Dezhou depression, Bohai Gulf basin, have been systematically studied. The relatively high abundance of dinostrance isomers and 24-n-propylcholestane have been identified in the Tertiary deposits of these regions. Based on their geological-geochemical significance, distribution and micro-fossil data, the authors tentatively postulate that the dinosteranes and 24-n-propylcholestane may be the product of transgression. They were derived from marine algae and can be regarded as the marker of transgression. |
