| 摘 要： | 吉林省东部地区以图们江构造带为界，其东西两区在生物地层、沉积建造和构造样式等诸方面存在显著的差异。其中石炭、二叠系的差异最为明显，三叠系的差异性明显变小。延边西部及吉林中部地区属于吉中地体，而延边东部地区则属于珲春地体，两者拼合的时间为Ｔ（１－２），图们江构造带是主拼合带。

| Abstract: | According to the difference of biostratigraphy,sedimentary sequence and tectonic style between central Jinn terrane and Hunchun terrane bordreed by north-south trending Tumenjiang fold-thrust belt,the eastern Jinn orogenic belt can be divived into two paleogeography provinces which exhibit strikingly different evolution histories of the Carboniferous and Permian.The similarity of widely distributing flora f Tianqiaoling flora and Laoheishan flora,indicats that the amalgamation of the two terranes took place before late Triassic. |
