摘要:
黄铁矿成因矿物学研究能够为深部成矿潜力评价提供重要信息。三山岛金矿超深钻孔(ZK96-6,2 735.70 m)揭露该矿床的矿化现象沿着三山岛断裂仍然可以延伸到深部(-2 613~-2 684 m)。为此,针对三山岛金矿深部钻孔岩芯矿化体(-2 613~-2 684 m)开展了黄铁矿成因矿物学研究,以探讨深部黄铁矿标型特征及其对深部成矿的指示意义。对不同阶段黄铁矿的形态标型进行细致观察,利用电子探针和等离子质谱仪对其进行主量和微量元素分析,利用热电仪对其进行热电性分析。研究结果表明:深部矿化体中石英—黄铁矿阶段脉体中的黄铁矿粒度相比其他阶段的黄铁矿更加粗大,指示成矿流体沉淀黄铁矿时处于强过饱和条件,成矿流体中的还原性硫在形成黄铁矿的过程中大量消耗并导致金硫络合物失稳而沉淀。深部金矿体(-2 613~-2 684 m)黄铁矿微量元素含量在(Au+Bi+Cu+Pb+Zn)-(As+Sb+Ba+Ag+Hg)-(Ti+Cr+Co+Ni)三角投图中的位置指示该处矿体属于矿化中部,暗示深部仍有矿化潜力。黄铁矿热电性分析结果显示,P型黄铁矿出现率(P%)与金品位呈正相关关系,指示金和P型黄铁矿共生,该特征可作为深部金矿找矿的依据,同时也暗示着三山岛金矿的深部仍有巨大的找矿潜力。
