Taking genetic analysis as a clue, with consideration of the development features of axial sedimentary system in Dongying depression, this paper discusses the sequence-climate cycle unit with high accuracy for faulted lake basin , points out the inclusive relation between different sequences, and analyzes and discusses the inner structure of the third class sequence and climate cycle.

This sequence includes 4 climatic cycles and 32 climatic stag.

Through the recognition and dissection of sedimentary system developmental features and climatic cycle units, a basic frame-work of the high-resolution sequence stratigraphic units is established.
