摘要
该文选取某地区岩浆岩作为研究对象,对岩浆岩的形成时代、岩石成因、岩浆源区以及形成的大地构造背景进行讨论,重新厘定花岗岩形成时间,恢复多个火山机构,为探索大陆地壳的构造演化提供了指导意义。
This paper discusses the formation age,occurrence,magma source area and geotectonic background of the magmatic rocks in intersection area of Zhangguangcailing-Wandashan mountains,redefines the formation time of the granites,and restores several volcanic institutions,providing a direction for exploring tectonic evolution of the continental crust.
