辽东半岛旅顺、金县、庄河、岫岩一带的中、上元古界和古生界部分地层遭受了低级—很低级的变质作用,构成了一个总体呈北东向展布的狭长变质带。该变质带与区内印支期北东向构造关系密切,并与印支期花岗岩侵入活动有内在联系,即印支期构造岩浆岩带控制了变质作用的发生与分布。变质作用类型以区域性动力变质作用为主,局部地段受岩浆活动的影响,显示了区域动热力变质作用的特点。据此,可以认为,辽东半岛区域动力变质带是经受以强烈抬升运动形式为主的印支运动的产物。
Some strata of the Upper Proterozoic and Paleozoic in the Lvdong Peninsula, Lushun, Jinxian, Zhuanghe and Xiuyan suffer low-grade and low-grade metamorphism and constitute a long and narrow metamorphic zone . The metamorphic belt is closely related to the Indosinian north-eastern structure in the area and is intrinsically linked to the Indosinian granite intrusive activity. The Indosinian tectonic magmatic belt controlled the occurrence and distribution of metamorphism. The metamorphism type is dominated by regional dynamic metamorphism, and the local area is affected by magmatic activity, which shows the characteristics of dynamic thermal metamorphism in the area. Accordingly, it can be considered that the Liaodong Peninsula regional PM is the product of the Indosinian movement undergoing intense uplifting movements.
