银矿位于大兴安岭东南坡的中段,林东—乌兰浩特段燕山期岩浆构造带以西。位于哈德乌拉—马鞍屯—乌兰图东西向断裂带的北侧,大兴安岭多金属成矿带的黄岗梁—甘珠尔庙—神山铁锡铅锌成矿亚带的中北段。银矿体赋存在强硅化酸性熔岩中,围岩蚀变以硅化为主,破碎带内蚀变以绿泥石化、绿帘石化为主,气水热液脉型矿体。
The silver deposit is located in the middle section of the southeastern slope of Daxinganling, west of the Yanshanian magmatic belt in the Lintong-Wulanhaote section. The northern part of the Huanggangliang-Ganjueliao-Kanshan-Tiexi-Pb-Zn metallogenic belt of the Daxinganling polymetallic metallogenic belt is located on the north side of the Hadewala-Ma’atun-Ulan Tu east-west fault zone. The silver ore body exists in strongly silicified acidic lavas. The alteration of the wall rocks is dominated by silicification. The alteration within the crust is chloritized and green-curtain petrified, and the gas-hydrothermal vein type orebodies.
