摘　　要：铜多金属矿赋存于晚三叠世马塘群中岩组,含矿岩石属钙碱性火山岩系列,水系沉积AS8异常元素套合好,浓集中心明显,矿床类型属与火山岩有关的喷流沉积—叠加改造型。The Cu multimetallic deposit is in I_ate Triassic Batang Group middle rock formation. And the ore bearing rock belongs to the calc -alkali volcanic rock series. The element of comprehensive anomaly AS8 in water system sediment is superimposed well, and the concentration centre is evident. It belongs to the ore deposit of effusive deposition-superimposed reformation type related with volcanic rock.
