The Dahutang tungsten—copper—polymetallic ore concentration area is located on the north side of the central Qinzhou—Hangzhou(QinHang) composite orogen, southeastern margin of Yangtze plate. Most exposed bedrocks in the area are the Jinning Period (Neoproterozoic) biotite granodiorite(mainbody of the Jiuling batholith), a few are low metamorphic fine elastic rocks of the Neoproterozoic Shuangqiaoshan Group(residual cap of the Jiuling Batholith), porphyritic granite, fine grained granite and granite porphyry of Yanshanian period. Methods: Based on the research results of comprehensive regional geological structure, this paper uses the principle of structural analysis to analyze the Yanshanian tectono—magma—mineralization in Dahutang Mining Area.Results: It is concluded that the super large tungsten—copper polymetallic oreforming in this area is closely associated with the occurrence, development and evolution of Yanshanian tectonic magmatic hydrothermal mineralization system, among which metallogenic structure and metallogenic structural surface are the basises of mineralization, and the metallogenetic rock body is the key to mineralization.Conclusions: Mineralization is the coupling results of metallogenic structure, metallogenic structural surface and metallogenetic rock body.
