摘　　要：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-complex structure distributed in Lushun-Dalian-Jinzhou-Zhuanghe-Pulandian area in the south of Liaodong Peninsula. In the east of this area, the thermal uplift, which was formed by t.he magmatic activities as a result of Pacific plate underthrusting Asia plate during Indo-Chinese cycle, resulted in the Mid-upper Proterozoic-Palaeozoic cover on the platform gliding extention from east to west. During the gliding extension movement, on the roof of Archean metamorphic core-complex, there was forming ductile shear zones;on the unconformity plane of the cover and basement,there was forming detachmant faults;in the cementer of the cover,there was forming tectonically deformed ductile layers and in the upper was tectonically deformed brittle layers. In brief,the metamorphic core-complex structure from lower to upper were metamorphic complex in the core;detachmant faults; tectonically deformed ductile layers in the centre; tectonically deformed brittil layers in the upper.
