| 摘 要： | 由于埕北凹陷中生代地层的划分主要根据区域地质资料及部分孢粉化石,而白垩纪沉积缺乏充足的古生物资料,因此难以系统、准确地划分。在对埕北凹陷老斜452井的古生物分析中,发现穴状女星介(相似种)Cypridea(Cypridea)cf.cavernosa、蒙阴女星介C.(C.)mengyinensis等介形类化石,说明该地区存在白垩系,这一发现对该区中生代地层的划分提供了重要的古生物学依据。

| Abstract: | The division of Mesozoic strata in Changbei sag mainly relies on the regional geological information and partialsporo-pollen fossils. It is difficult to divide the Cretaceous systematically and exactly because of the lack of Paleontologic information in the Cretaceous sediment. The Ostracoda fossils Cypridea (Cypridea) cf. caverno-sa,C. (C. ) mengyinensis and so on were found during the Palaeontology analysis in well Laoxie 452 in Cheng-bei sag, which indicate the existence of Cretaceous in this area. The discovery provides an important Palaeontology information for the division of Mesozoic strata in the researching area. |
