对秦岭沙沟韧性剪切带的主要岩石类型长英质糜棱岩的组构和变质矿物组合研究表明，其至少经历了３期构造事件，主变形期发生在角闪岩相条件下，温度约５３０℃；持续的岩浆分融／侵入和剪切作用是形成该糜棱岩的重要机制。
The main rock types of the Shagou ductile shear zone in the Qinling Mountains The study on the structure and metamorphic mineral assemblages of the feldspathic mylonites shows that they experienced at least three tectonic events and that the main deformation occurred in the amphibolite facies. The temperature About 530 ℃; continuous magmatic melting / invasion and shearing are important mechanisms for forming this mylonite.
