摘    要:辽宁东、西部地质上诸多差异并非是原地升降运动造成的,而是二个异地岩块经郯庐断裂大规模左旋平移运动迁移到一起的结果。辽东半岛原曾与鲁西-徐淮地区处于相同的古纬度。郯庐断裂北延的主干断裂应是抚顺-敦化断裂,它在辽宁境内是地层区划的重要界线。郯庐断裂在太古宙末期即已出现,曾多次变换其平移方向,最近一次大规模左行平移活动的高峰期是在晚侏罗世晚期-早白垩世,结束于孙家湾组或泉头组堆积之前。

关 键 词:郯庐断裂,平移运动,辽东半岛,鲁西,建造,岩相带,补偿构造

Abstract:From the geological correlation and analysis,this paper proven that many differences ongeological characteristics between East and West Liaoning resulted from two massives on dif-ferent sites removing to the same place through large-scale left-lateral translation movementof Tan-Lu fracture,rather than autochthonous vertical movement.East Liaoning Peninsulahad been in the same paleolatitude with West Shandong-Xuzhou-Huai'an area. Fushun-Dun-hus fracture,as the main fracture of Tan-Lu fracture belt extending northward is an impor-tant boundary for stratigraphically dividing in Liaoning,This paper believes that Tan-Lufracture belt occurred in the end of late Archean and its translational direction varied manytimes,but the peak period of the latest large-scale left-lateral translation movement rangedfrom late Jurassic to Early Cretaceous and ended before the accumulation of Sunjiawan For-mation or Quantou Formation.
Keywords:Tan-Lu fracture Translation movement East Liaoning peninsula WestShandong Formation Lithofacies belt Compensation structure
