A study on the Yongzhu junction zone controlling rock and mineralizing process

The Yongzhu metallogenic belt was formed in the late Jurassic-early Cretaceous (J3-K), in the evolutionary process of the extension-spreading, closure-collision, it formed two metallogenic serieses and four subserieses. In the intermediate acidity rock magma metallogenic series, Au, Cu, Pb, Si and W become useful metallogenic elements, characterized by the magmatic hydrothermal-contact replacement type; in the basic, ultrabasic magmatic activities, Cr, Au, Ac and Pt become useful metallogenic elements, characterized by the magmatic liquation, hydrothermal injection and tectonic (metamorphic) hydrothermal type, we should lay stress on the Pt element in the working.
