| 摘 要： | 依据黑龙江汤原断陷30口井的岩性及古生物资料,建立了汤原断陷古近纪、新近纪地层层序。依据孢粉、藻类、植物和介形类化石建立19个生物化石组合,讨论了各组的时代及其与邻区的对比。依据汤参3井(25.0-100.0m)和互6井(138.5-237.5m)岩性及孢粉组合将道台桥组引入汤原断陷。汤原断陷地层层序为古新统乌云组,始新统新安村组、达连河组,渐新统宝泉岭组,中新统富锦组,上新统道台桥组。

| Abstract: | The Paleogene and Neogene strata in the Tangyuan Rift have been collated on the basis of litho-logic characters and fossils of 30 drilling-wells. 19 fossil assemblages have been established on the basis offossil sporo-pollen, plants, algae, megaspore and ostracodes. The age of each formation in the Rift is dis-cussed and the strata in the Tangyuan Rift wi1l be correlated with the strata of the neighboring regions. Ac-cording to lithologic characters and sporo-pollen assemblages of Tangcan 3 well (25.0-100. 0m) and Hu 6well (138.5-237.5m),the Daotaiqiao Formation is used in the Tangyuan Rift. Therefore the sequences ofPaleogene strata in the Tangyuan Rift are respectively the Paleocene Wuyun Formation, Eocene Xinanchunand Dalianhe Formations, and Oligocene Baoquanling Formation. the sequence of Neogene strata in theTangyuan Rift are respectively the Miocene Fujin Formation and Pliocene Daotaiqiao Formation. |
