Dongguashan Copper (gold) deposit is located in the northeast of the Yangtze craton, which belong to the lower Yangtze Syneclise Fanchang Guichi concave fault-fold belt (Tang et al., 1998). It occurred in North East section of Qingshan anticline, secondary structure of DatongShunan multiple syncline. The formation closely related to mineralization including upper Devonaian Wutong formation (D3w) quartz sandstone, middle-upper Carboniferous Chuanshan and Huanglong formation (C2+3) carbonate rock, lower Permian Qixia formation (P1q) limestone, chert and skarn. The complex reticular structure-framework in this area is compesed of NE trending folds and faults of Indosinian and nearly SN-, EWand NNE trending faults, interlayer structure and joint. Magmatic rock emplaced along the complex structure systems, showed dyke and apophysis in shallow. Qingshanjiao composite rock body is closely related to mineralization, composed by granodiorite and porphyraceous quartz monzodiorite.
