摘要
大连地区经历了漫长而又特殊的地质构造演化过程 ,自中生代以来 ,全区处于活动大陆边缘环境 ,并遭受多期构造变形事件的影响。其中大规模南北向剪切滑褶变形为首次发现并确定 ,其为区内众多变形事件中规模最大、影响最广的一期构造事件。本文在详细的地质调查基础上 ,初步研究分析了研究区南北向剪切滑褶变形的构造 -岩石组合特征及变形模式 ,并就变形动力学背景及变形时代进行了探讨。
Dalian area has undergone a long and specific geological-structural evolutionary process. The study area has been the structural background of active continental margin since Mesozoic, and has suffered the influence of multideformation, in which the NS-trending shear traction deformation is the largest and most widespread in scale. This paper has determined the characteristics as well as the model and age of the deformation on the basis of geological investigation. The results obtained have enriched the research substance of Indosinian movement in Sino-Korean plate.
