辽东半岛南部变质核杂岩构造展布于旅顺、大连、金州、庄河、普兰店地区。印支旋回太平洋板块对亚洲板块俯冲作用引起的岩浆活动在本区东部形成热隆起,诱使陆台中上元古界—古生界盖层自东向西滑移伸展.随伸展运动的进行,在太古宙变质杂岩顶部形成韧性剪切带;在盖层与基底不整合面形成剥离断层;在盖层内部形成中间韧性构造变形层和上部脆性构造变形层。在不同的构造层次中形成样式各异的构造群落,同时伴随变质作用及成矿作用。
The metamorphic core complexes in southern Liaodong Peninsula are distributed in Lushun, Dalian, Jinzhou, Zhuanghe and Pulandian. The Indosinian Pacific plate tectonic movement induced by the subduction of the Asian plate formed a thermal uplift in the eastern part of the area, which induced the slip of the Upper Proterozoic-Paleozoic cap rocks of the Lutai Middle out from east to west. With the extensional movement, ductile shear zones are formed on the top of the Archean metamorphic complex; delamination faults are formed on the unconformity between the caprock and the basement; and the intermediate ductile deformation zone and the upper brittle deformation zone are formed in the caprock. The tectonic communities with different styles are formed at different tectonic levels with metamorphism and mineralization.
