| 摘 要： | 简要报道东海陆架浙东坳陷西湖凹陷之宝石一井T4°地震反射层以下深部地层 (井深 344 7m以下 )的古生物资料 ,并探讨其年代地层属性。经初步分析研究 ,这深部层位含有有孔虫、钙质超微化石、沟鞭藻和海相介形类等微体化石 ,以及见有尚不能判断是否为原位的孢粉化石。根据微体古生物的地质分布以及其它钻井深层所含微体古生物比较 ,认为宝石一井T4°反射层以下地层为西湖凹陷揭示的一套新的地层 ,其年代属古新世

| Abstract: | This paper mainly reports the microfossils including coccoliths, foraminifers, dinoflagellates, ostracods and palynomorphs from the deep beds (interval 3 447? ? 806 m ) exposed in the well Baoshi 1# of Xihu Sag and discusses its chronostratigraphy. According to the geological distribution of these microfossils and a comparison with those fossils from formerly drilled wells in Xihu Sag, the authors hold that the intervel covering these deep beds of the well Baoshi 1# is a set of newly found strata and belongs to Paleocene. |
