Abstract

Abstract: Isochronous sequence stratigraphy is identified by using palynological and seismic data.Through the establishment of palynological climatic information function，the temperature and moisture curve of Paleogene in Liao-dong Bay depression is drawn.Based on temperature and moisture feature，Paleogene is divided into 1 first-order，4 second-order and 11 third-order climatic cycles.The climate swing function is analyzed by combining the lacustrine level change curve.From the analysis，it can be concluded that the climate has a close relationship with the lake level.It can control sequence，sedimentary and source rock.

Key words: sporopollen, palaeoclimate, sequence stratigraphy, information function, Paleogene, Liao-dong Bay
