| 摘 要： | 花岗岩具成矿专属性。在不同大地构造背景及造山作用不同阶段，不同源岩的部分熔融形成类型、矿物学和地球化学成分、成因、分异演化均不同的花岗岩类，出现不同程度的环带构造、断裂构造和交代作用现象，它们均与相关的成矿元素组合具有一定的相关关系，对花岗岩成矿起关键性的控制作用。本文归纳总结了花岗岩成矿的几个判别标志：大地构造背景、花岗岩的环带构造、成矿流体可迁移性及自交代作用、矿物学和地球化学特征。

| Abstract: | Granites have metallogenic specialization. At different tectonic settings and different orogenic stages, granitoids of various types, mineralogical and geochemical compositions, geneses, and differentiation evolutionary histories are formed by melting of different sources, and different zonations, fractures and metasomatisms are produced in granitoid plutons. There is correlation between them and associations of metal elements. Also, they play a key role in controlling mineralization of granitoid. Some diagnostic criteria for mineralized granites are summarized and reviewed, which include tectonic setting, zonation of granite, mobility of ore fluid, and geochemical and mineralogical indicators. |
