| 摘 要： | 花岗岩类具有成矿专属性。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、岩石学和地球化学成分、成因、分异演化均不同的花岗岩类,它们均与相关的成矿元素组合具有一定的相关系,对花岗岩类成矿起关键性的控制作用。由此可见在判别花岗岩类的成矿专属性时需要综合考虑:野外判别、岩石化学成分判别、地球化学特征判别、花岗岩类成矿元素组合的大地构造控制判别。

| Abstract: | Granitoid 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 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. Thus in the discrimination of Granitoid in the metallogenic specialization when considering： the field discriminant, the chemical composition of rocks, geochemistry discrimination, discrimination of Granitoids of metallogenic elements combined tectonic control criterion. |
