银山斑岩型铜铅锌(银)矿床位于萍乡―钱塘拗陷带、万年隆起亚带,赣东北深大断裂上盘。区内地质构造复杂,火成活动频繁,成矿条件相当有利,已探明多个大型以上金属矿床,为我国有色金属和贵金属高度集中区之一。1成矿地质背景1.1地层矿区地层主要由基底中元古界双桥山群浅变质岩系和盖层中生界上侏罗统鹅湖岭组火山
Yinshan porphyry-type copper-lead-zinc (silver) deposit is located in Pingxiang - Qiantang depression belt, Wannian uplift sub-zone, northeast Jiangxi deep fault hanging plate. The geological structure in the area is complex and the volcanic activity is frequent. The metallogenic conditions are quite favorable. Several large and large metallogenic deposits have been discovered, which is one of the highly concentrated areas for nonferrous metals and precious metals in our country. 1.1 Geological background 1.1 Ore strata The strata in the mine area are mainly composed of the metamorphic metamorphic metamorphic rocks in the basement metamorphic rocks of the Shuangqiao Group and the Upper Jurassic Ehushu Formation volcanic
