本文采用了“锆石与花岗岩岩石学”—文中锆石形态学研究方法,对野马地区不同构造岩浆活动期形成的花岗岩岩体中锆石形态学进行了研究。野马地区主要花岗岩体系华力西晚期和燕山早期岩浆活动的产物。华力西晚期花岗岩代表性岩体有金山堡岩体和四平山岩体。综合研究认为:金山堡岩体为华力西晚期第一阶段形成,岩体呈岩基状产出,分异不好,岩石类型主要是斜长花岗岩,岩石化学类型属钙碱性系列,副矿物组合为磁铁矿——锆石——磷灰石型,四
In this paper, “zircon and granite petrology” - the zircon morphological study, was used to study zircon morphologies in granitic rocks formed during the tectono-magmatic activity in the Mustang region. The main granitoids in the Mustang are the products of the late Variscan and early Yanshanian magmatic activities. Representative rocks of the late Warisi granites include Jinshanbao and Sipingshan plutons. Comprehensive study shows that: Jinshanbao rock body is formed in the first stage of the late Variscan stage, the rock mass is produced in a rocky base, the differentiation is not good, the rock type is mainly plagiogranite, the rock chemistry type is a series of calcium and alkali, the vice Mineral combination of magnetite - zircon - apatite, four
