tectonic metamorphism

Because of this three stage tectonic stress superposition effect, ore bodies in the area occurs fault, fold and other complex deformation metamorphism.

由于受此三期构造应力的叠加作用，矿体在区内发生了错断、褶皱等复杂的变形变质作用。

Tectogenesis, especially tectonic metamorphism is more important to the formation of the migmatite& metamorphics zone.

构造活动，尤其是构造变质对变质&混合岩带的形成起了相当重要的作用。

The country rocks of the ores are characterized by heat contact metamorphism and metasomatism and clearly controlled by tectonic structures and magmatite.

矿体围岩具有热接触变质、接触交代变质特点，受断裂构造、岩浆岩控制明显。

Through an integrated analysis of the types of tectonic deformation and metamorphism, order of their formation, emplacement of plutons and isotopic age data, this paper discusses the regional distribution and formation ages of metamorphic rocks and their role and significance in the process of crustal evolution.

通过对构造变形与变质特征、形成序次、深成岩侵位及同位素年龄资料的综合分析，阐明变质岩的区域分布和形成时代，及其在地壳演化中的作用和意义。

Detailed research suggests the following tectonic evolution model: Thermal metamorphism was related to intra island arc tension, while regional faulting metamorphism was caused by A type subduction in the process of collisional orogeny. Phenomenon

这一研究反映了哈尔里克泥盆纪火山岛弧经过了由拉伸作用到碰撞挤压造山引发的A型俯冲作用演变过程，并产生了上述相应的变质现象
