| 摘 要： | 黔西北威宁地区香炉山铜矿床位于二叠系峨眉山玄武岩组第3段(P3β3)顶部与宣威组(P3x)底部之间,属于玄武岩型铜矿床。针对其含矿地层宏观地质特征与赋矿主岩矿物岩石学组构,本文以野外地质为基础,系统开展岩矿鉴定、扫描电镜与电子探针分析等研究,结果表明,本矿床赋矿主岩为岩屑粉砂岩的矿石矿物为辉铜矿、斑铜矿、黝铜矿和孔雀石,脉石矿物为长石、石英、绿泥石和碳质物等;赋矿主岩为火山角砾岩的矿石矿物为自然铜、斑铜矿、黄铜矿、辉铜矿、黝铜矿和孔雀石,其脉石矿物为石英、绿泥石、白云石和粘土矿物等,按其主要矿物含量,原生矿石可分为自然铜+辉铜矿+赤铁矿矿石、自然铜+黄铜矿+黝铜矿矿石、黄铜矿+斑铜矿+赤铁矿矿石3种自然类型。根据矿物共生组合与相互穿插关系,本矿床成矿作用可分为热液期和表生期,其中,热液期矿石矿物的形成顺序为斑铜矿→黄铜矿—黝铜矿—自然铜→辉铜矿,表生期形成孔雀石、赤铜矿、赤铁矿、钛铁矿、褐铁矿等矿物。
