| 摘 要： | 针对研究区钻及二叠系的井甚少，现有的几条地震剖面质量欠佳的状况，采用露头层序地层学的方法在８条主干剖面、数十条辅助剖面详细研究的基础上将研究区二叠系划分为１１个Ⅲ级层序（栖霞阶为３个层序，茅口阶为３个层序，吴家坪阶为３个层序和长兴阶为２个层序）。以具区域性分布的生物化石带为主，辅以岩性组合、岩相特征、垂向相序特点及地质事件，对研究区二叠系进行详细区域层序对比，总结了二叠系层序特点。

| Abstract: | Owing to very few logs and inferior seismic profiles in the study area,the method of outcrop sequence stratigraphy is used.On the basis of detailed studies of eight sections,the Permian rocks in the Lower Yangtze Region are diveded into eleven third order sequences,namely Chihsian Stage of 3 sequences,Maokouan Stage of 3 sequences,Wuchiapingian Stage of 3 sequences and Changhsingian Stage of 2 sequences.Based on the regional biozones,lithological assemblages and facies characteristics,vertical sequences and geological events,the authors make the correaltion of the Permian sequences in the Lower Yangtze Region and summerize the sequence charateristics. |
