摘　　要：山西省灵丘县硐沟锰银矿位于晋东北金银多金属成矿区中NW向中庄铺—刘庄成矿带中段的太白维山银锰多金属矿田内,共圈出4条锰矿体,8条锰银矿体,15条银矿体。矿区呈单斜构造,矿体受南北向断裂控制,主要产于中上元古界长城系高于庄组、蓟县系雾迷山组白云岩和燕山期大北沟石英斑岩接触带附近,为沉积—岩浆热液富集型锰银矿矿床。Donggou Manganese Silver Mine is located in Taibaiweishan silver manganese polymetallic ore field in the middle part of NW.It is trending Zhongzhuangpu-Liuzhuang metallogenic belt in Northeast of Shanxi Province.There are 4 manganese ore-bodies,8 manganese Silver ore-bodies and 15 silver ore-bodies.The ore body is monoclinic structure,and it is controlled by north-south faults.It mainly occurs near the contact zone of dolomite of Gaoyuzhuang Formation of Changcheng System and Wumishan formation of Jixian system in Middle Upper Proterozoic and Dabengou quartz porphyry in Yanshan period.At the same time,it is controlled by the North-South fault.The deposit is a deposit of sedimentary magmatic hydrothermal enrichment type manganese silver deposit.
