并不是所有的花岗岩类建造客体的地球化学专属性对成矿预测有指导意义,而各别的含矿相的地球化学专属性对成矿预测有指导意义。这种相仅占花岗岩类建造的一小部分,也就是说里边发生了静态矿石富集作用、物质分异作用和矿石堆积作用。查明此种含矿相的地球化学专属性就成为了从地球化学角度进行成矿预测的基本任务。事实上,含金矿的花岗岩类建造相也就成为了各种花岗岩类建造中大比例尺预测的对象。 Not all geochemical specificities of the granitic-built objects are instructive for metallogenic prediction, and the geochemical specificity of individual ore-bearing phases is instructive for metallogenic prediction. This phase accounts for only a small part of the granite construction, which means that there are static ore enrichment, material differentiation and ore accumulation. Identifying this geochemical specificity of the ore-bearing facies has become the basic task of mineralization prediction from a geochemical point of view. In fact, the gold-bearing granitoids have also become the object of large-scale prediction in the construction of various granites.
