| 摘 要： | 黔东南州从江县那哥铜多金属矿床位于江南造山带西南段，是该区代表性的多金属矿床。工业矿体呈层状、似层状赋存于青白口系甲路组（Qbj）和乌叶组（Qbw）的浅变质沉积岩中，受断层控制明显，产于F2断层破碎带内。区域构造岩浆活动频繁，基性一超基性和中一酸性岩浆广泛发育。那哥铜多金属矿床矿石硫化物的8^34scDT值介于-2．7％0～2．8％0之间，均值为0．1‰；黄铜矿8cuNBs6值变化范围为-（3．09％0～0．33％0；脉石矿物石英包裹体δDSMOW和δ^18H2O值范围，分别为J50．一44．和．～．，暗示该矿床成矿流体具有深源岩浆水和浅变质围岩变质水,O的混合特征，成矿流体7％中0的硫和4％铜0具7有9深％部0岩9浆0％来0源特征。地球物理电性测量结果显示，矿石和不同类型岩石间具有明显的电性（电阻率和视极化率）差异，并以此圈定多个异常靶区，显示本区具有良好的找矿前景。
