| 摘 要： | 隆措沟富银铅锌矿位于川西义敦岛弧造山带北段火山—沉积盆地内。矿体产出受层间破碎带和断裂控制,容矿岩石为上三叠统拉纳山组浅变质岩。金属矿物主要有方铅矿、闪锌矿、黄铁矿,少量砷黝铜矿、磁黄铁矿等。其矿化特征与呷村大型银多金属矿床相似,属同一成矿系列。该富银铅锌矿的发现与勘查,进一步丰富了该区成矿系列的矿床类型,为银多金属矿的找矿拓宽了思路,扩大了找矿范围和远景。

| Abstract: | The Longcuogou Ag-rich Pb-Zn deposit is located in a volcanic sedimentary basin in the northern section of the Yidun island arc.The orebodies are controlled by interstratified rupture zones and faults.The host rock is epimetamorphic rock of the Upper Triassic Lanashan Formation.Ore minerals are galena,sphalerite,pyrite,small amount of tennantite and pyrrhotite.The mineralization is similar to that of the Gacun Ag-polymetallic deposit. |
