大兴安岭中南段有色金属成矿带位于天山-兴蒙造山带东部贺根山断裂与西拉沐伦河断裂之间,是兴蒙造山带的重要组成部分(刘建明等,2001)。大地构造位置处于古亚洲洋成矿域与环太平洋成矿域的叠加部位(Zeng et al.,2013,2015)。复杂的区域构造、岩浆演化历史形成了该区丰富和颇具特色的矿产资源,特别是银铅锌矿床(张德全等,1994;Zeng et al.,2011;Ouyang et al.,2014)。近些年来本 The middle-south Daxinganling nonferrous metallogenic belt is located between the Tengshan-Xingmeng orogenic belt and the West Rimunlun fault. It is an important part of the Xingmeng orogenic belt (Liu et al., 2001). The tectonic location is superimposed on the mineralization of the Archean Ocean and the Pacific Rim (Zeng et al., 2013, 2015). Complex regional structures and magmatic evolution have formed rich and distinctive mineral resources in this area, especially silver-lead-zinc deposits (Zhang et al., 1994; Zeng et al., 2011; Ouyang et al., 2014).
