摘　　要：山东滩海地区位于胜利油气区东部沿海一带,自北向南依次为埕北凹陷、埕子口凸起及沾化凹陷东部的桩西、五号桩和孤东等地(图1)。多年来的石油地质勘探表明本区下第三系构造单元复杂,沉积类型多样,地层的超覆、剥失现象普遍。The principles of biostratigraphy,sedimentology and element geochemistry are comprehensively applied to the study of the Paleogene of the Shore Zone of Shan- dong Province.During the deposition of the Kongdian to Dongying Formation,the sedi- ments of lake facies dominated this area,with sediments of fluvial and alluvial facies oc- curring on some occasions.The Nos.1 and 2 members of the Shahejie Formation include respectively five(Ilyocyprimorpha jinanensis-Tuberocyproides sulcata,Cypria gargara- Eucypris faviformis,Carnarocypris elliptica-C,longa,Pseudocandona longa and Virgato- cypris triangularis communities)and three ostracod communities(Lirnnocypthere arma- ta-Pseudocandona deplanata,Miniocypris subtriangularis-Phacocypris panheensis and Xiyingia luminosa-Guangbeinia xinzhenensis communities).
