Meiziwo tungsten deposit, located in Guangdong province, is a cradle for establishment of the model of “Fivestoryed” quartz veins in China. Drilling in recent years revealed that tungsten ore vein does not disappeare after extending two to three kilometers inside granite, which is discrepancy with the conventional model of “Fivestoried” quartz veins. Based on previous work and systematic observation in the field, along with comparison study, two hidden granite intrusive events have been identified in the deep part of the Meiziwo tungsten deposit and correspond to two quartz vein type tungsten mineralization events respectively. Spatically, these veins are vertically superimposed, forming a “Fivestoried” superimposed model, which is of great significance at deep exploration of mine area.
