摘　　要：班公湖-怒江成矿带是一条以矽卡岩-斑岩型铜金矿为主的金铜多金属成矿带。该文对在该带西段新发现江玛南铜银矿点地质特征进行了论述。江玛南铜银矿赋存于去申拉组火山岩中,受破碎构造带控制,属于与火山机构有关的热液型矿床,具有浅成低温热液型矿床的特征,成矿后受到次生氧化作用。该矿床的发现对该地区寻找浅成低温热液型-斑岩型矿床有重要的指导意义,显示班公湖-怒江成矿带除其南北两侧外,带内同样有寻找浅成低温热液-斑岩型铜金多金属矿的潜力。The Bangong Co-Nujiang metallogenic belt is a Au-Cu-polymetallic belt where skarn-porphyry type Au-Cu deposits dominate. The Jiangmanan Cu-Ag ore spot is newly discovered in the western part of the Bangong-Nujiang suture zone. The ore spot is confined to volcanic rock of the Qushenla Formation and controlled by the fracture zone, being a hydrothermal ore spot related to volcanic apparatus and characteristic of hypabyssal epithermal mineralization. This discovery indicates potential searching for hypabyssal epithermal porphyry Cu-Au-polymetallic ores in the Bangong Co-Nujiang suture zone.
