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。
