| 摘 要： | 渤海湾盆地沙河街组中钙质超微化石的发现,表明这一时期渤海湾盆地与海水有过联系。对钙质超微化石古生态及沉积环境研究表明,化石主要产出时代为始新世晚期至渐新世早中期,属“间冰期”亚热带气候型。这一问题的深入研究,对于渤海湾盆地的石油勘探有重要意义。

| Abstract: | The calcareous nannofossil has been discovered in Shahejie Formation of the Bohaiwan Basin which shows that the Bohaiwan Basin has been related to the sea water during the period. The study on the calcareous nannofossil paleoecology and depositional environment demonstrates that the main era of the nannofossil is from Late Eocene to Early-Middle Oligocene, which belongs to the subtropic climate in the interglacial period. A thorough study on this subject will be of significant importance for the petroleum exploration in the Bohaiwan Basin. |
