The Guzhu molybdenum （copper） or deposit, She County lies in the Baijiling arc belt inside the Jiangnan Old Uplift Zone of the Jiangnan Massif, in the Wuliting-Changgai NNE-trending tectonomagmatic belt. In the ore field, metamorphic rhyolitic tuff has turned into sericite quartz schist, forming a compressive schistosity belt, generally trending NE and dipping SE. The main structure is a NE fault, big-sealed, thrusting and oblique thrusting. The ore-forming parent rock is late Jurassic fine-grained porphyritic granodiorite of syntectic type. Molybdenum ore body dominates in the deposit compared with copper ore body. Molybdenum-bearing Ores are composed mainly molybdenite and pyrite, and copper-bearing ores of chalcopyrite and pyrite. In the Yanshanian period, the Jiangnan intracontinental orogen formed in the deep process of crust-mantle interaction, with stretching and thrusting of the deep and major Qimen fault, lithospherie thinning led to decompression melting, basic magma underplating occurred at crust-mantle border and caused local melting of lower crust to form intermediate-acid magma. Magmatie evolution and differentiation, and molybdenum enrichment in magmatic hydrothermal solution finally gave rise to ore-bearing solution. With change in stress, mineral substance separated out and deposited to form ores.
