| 摘 要： | 高邮凹陷D1井富含介形虫、轮藻和孢粉等化石。通过系统的微体古生物分析，首次对该地区白垩纪一古近纪微体古生物地层进行了精确划分，从下到上共建立11个化石组合：其中介形虫4个，轮藻4个，孢粉3个。文中还简要探讨了沉积环境演变，为该地区油气勘探提供有力的生物地层依据。

| Abstract: | The microfossils including ostracods, charophytes and spore-pollen are abundant in the Well D1, Gaoyou depression, Northern Jiangsu Basin. According to analyses of the microfossils, eleven assemblages including four ostracod assemblages in the Upper Paleocene to Eocene, four charophytes assemblages in the Upper Cretaceous to Eocene and three spore-pollen assemblages in the Upper Cretaceous to Upper Paleocene were established. The micropalaeontological stratigraphy subdivision and the changes of depositional environments were studied in this paper. This study will provide valuable biostratigraphic and palaeoenvironmental evidences for the oil exploration in this area. |
