摘要
本文简要概述了渤海湾盆地锦州25-1南地区古近纪生物组合特征和地层层序,建立了4个孢粉藻类组合,3个介形类化石组合,1个钙质超微化石组合,进而根据化石组合及其特征,讨论了化石组合在地层划分对比中的意义和地层展布及演化情况。
Based on the integration of detailed data of paleontology,lithology and logging, associated with regional geological and seismic information, this paper concerns with the integrated study of strata sequence and paleontology of JZ25-1S area of Bohai Basin. As a result, 8 fossil assemblages （3 ostracoda assemblages, 4 algae ＆ spore-pollen assemblages and 1 calcareous nannofossil assemblage） were established for JZ25-1S area. Then based on stratigraphic correlation, fossil distribution and evolution are discussed.
