Abstract Huge scale red beds-gypsum salt beds sediments were developed during the period of the Member 1 of Kongdian Formation(Ek1)and the lower submember of the Member 4 of Shahejie Formation(Es4x)of Paleogene in Dongying Sag，Jiyang Depression.It was recognized that red beds-gypsum salt beds sediments were characterized by the coexistence of aquatic sedimentation and subaqueous sedimentation and coexistence of gravity current sedimentation and traction current sedimentation. The vertical superposition styles of red beds-gypsum salt beds sediments are quite different at different positions of the Dongying Sag. Based on the analyses of sedimentary characteristics，grain size of clastic and vertical superposition style.According to the analyses of characteristics of geochemistry and color of mudstone and previous researches，the sedimentary environments of the period of red beds-gypsum salt beds development was dominated by dry climate and dry climate and wet climate were alternate frequently.The salinity of the lacustrine basin was relatively lower and the sediments were mainly sandstones and mudstones during the period of wet climate，while the salinity was relatively higher and the sediments were mainly gypsum salt during the period of dry climate.The lacustrine basin was a oscillatory basin with a lower water level at the early and middle periods of Ek1-Es4x and was changed to a higher water level oscillatory lacustrine basin at the late periods of Ek1-Es4x，which have different characteristics of sedimentation.
