1.辽东——吉南构造区特征按地层区划,本区统属华北区东北端的辽东分区。本区南西隔海与胶东相望,南东接朝鲜北部,三者为一统一的构造单元“胶辽——狼林地块”。总的是一结晶基岩隆起,它虽是中朝准地台的一部分,但与其西之华北地块在基底岩相等方面仍有所不同。回溯先震旦的历史,每一阶段都有其特定的构造体制和组合。晚太古宙时,华北地台尚处从陆核向萌地台演化的阶段;后经阜平运动(26—24亿年),陆核扩大、联合,才构成了华北萌地台。自此,方始元古宙的地质演化史。早元古宙早期(25—20亿年),萌地台的周边形成了活动带——萌地槽,本区即处
1. Liaodong - Ji Nan tectonic features by stratigraphic division, the district belongs to the northeast end of North China Liaodong district. The area south across the sea and Jiaodong across the south east of North Korea, North Korea, the three for a unified structural unit “Jiaoliao - Wolf Forest plots.” In general, a crystalline basement rock uplift, although it is part of the Sino-Korean quasi-platform, but with the West of the North China block in the same basement rock is still different. Back to the history of the first Sin Dan, each stage has its own specific structure and composition. Late Archaean, the North China platform is still at the stage from the evolution of the terrestrial nuclear to the Meng stage; after the Fuping Movement (26-2.4 billion years), the expansion of the nuclear union, it formed the North China Meng station. Since then, the geological evolution of Fangyuan Proterozoic. Early Early Proterozoic (2.5-20 billion years), adorable platform around the formation of the activity zone - Moe slot, the district that is
