摘　　要：大兴安岭南段是中国重要的有色金属成矿带,区内发育众多锡银铅锌等多金属矿床。双尖子山银铅锌多金属矿床是近年来发现的一个以银为主的超大型矿床,前人研究普遍认为该矿床是典型中低温岩浆-热液型矿床,缺乏高温成矿阶段。然而,文章在该矿床的井下和深部钻孔发现了大量铜锡矿化,表明双尖子山银多金属矿床的深部和外围具有巨大的锡铜资源找矿潜力。The southern section of the Great Xing’an Range is an important nonferrous metal metallogenic belt in China,containing many Sn-Ag-Pb-Zn polymetallic deposits.Shuangjianzishan Ag-Pb-Zn polymetallic deposit is a super-large deposit mainly composed of silver discovered in recent years.Previous studies generally believe that this deposit is a typical medium-low temperature magmatic-hydrothermal deposit,lacking a high-temperature metallogenic stage.In this study,a large amount of copper and tin mineralization was found within the underground and deep drills in this area,indicating great prospecting potential for tin and copper mineralization in the deep and peripheral areas of the Shuangjianzishan Ag polymetallic deposit.
