Abstract: The results of a new study of Oligocene series in Zhoukou Basin are reported in the present paper.Based on a composite analysis of existing data,some previous recognitions have been changed.Ostracodes,charophyte,spore-pollen fossil assemblages have been established.The existence of Oligocene series in the eastern basin is confirmed and the series is classfied for the first time.The differences between Oligocene series in the east and west are demonstrated.
