| 摘 要： | 刘山岩块状铜锌硫化物矿床产于寒武系二郎坪群刘山岩岩组的石英角斑岩-硅质岩中。矿体呈脉状和透镜状产出，受刘山岩韧-脆性断裂的控制，产状与地层基本一致，但品位和厚度变化较大。矿石矿物主要为闪锌矿、黄铁矿与黄铜矿，脉石矿物为石英、绢云母、重晶石和绿泥石。矿石具自形-半自形晶结构、它形晶结构、斑状结构，浸染状、块状和条带状构造。矿石结构构造特征和围岩蚀变特征都表明该矿床为火山-喷流型块状硫化物矿床。

| Abstract: | Liushanyan Cu-Zn massive sulfide deposit is hosted by quartz keratophyre and silicalite in Cambrian Liushanyan Formation of Erlang Group.The orebodies is characterized by veins and lens and is controlled by Liushanyan ductile-brittle fault.The orebodies is distributed approximately parrallel to the Liushanyan Formation with variable ore grade and thickness.Ore minerals in orebodies is characterized by sphalerite,pyrite,and chalcopyrite and gangue minerals characterized by quartz,sericite,barite,and chlorite... |
