根据巢湖地区3条代表性下三迭统剖面的岩石地层、生物地层和碳同位素地层的最新研究成果归纳出本区早三迭世综合地层序列，作为区域地层对比研究的标准。

Based on the theory of Sequence Stratigraphy and the systematically analysis of strata which was closely focused on Lithostratigraphy, Biostratigraphy, Paleoecology Event Stratigraphy and Sequence Stratigraphy, four long-term base-level cycles can be recognized in the Mesozoic, each long-term base-level cycles can be further divided into intermediate-term to short-term base-level cycle. Eight intermediate-term base-level cycles are recognized in Mesozoic; Cenozoic can be divided into two structural base-level cycles, and can be further divided into seven long-term baselevel cycles.

应用层序地层学理论，在详细的岩石地层、生物地层、生态地层、事件地层和层序地层为核心的综合地层研究基础上，将中生界划分为四个长期基准面旋回，每个长期基准面旋回内部又可进一步识别出更次一级的旋回，侏罗系内部共可识别出8个次级旋回；根据钻井层序地层与地震地层划分结果，将北缘地区新生界划分为两个构造基准面旋回，其内部又可进一步划分为7个长期基准面旋回。
