| 摘 要： | 本矿床属石英脉型、近年发现于滇西南边陲。作者以背散射扫描电镜、电子探针及等离子光谱诸方法，对矿石中黄铁矿的矿物标型特征做了较深入研究，结果表明：黄铁矿为主要载金矿物，尤以具破碎结构的立方－五角十二面体聚晶含金最富。该矿物热电性金属Ｐ型导电、热电系数在垂向上无大变化，预示本矿床深部仍具一定远景，本研究有助于探讨矿床成因，且为深部预测可提供一定的科学依据。

| Abstract: | Gongding Au deposit is a quartz-vein type An deposit recently found in the southwest Yunnan Poovince. The authors deal with typomorphic characteristics of pyrite from the deposit by back seatering scanning electronic microscope,electronic probe and plasma spectrum. The results reveal that An-carriers are mainly pyrites among which pyritohedron is the most important one. Heat and electric conductive curve are all P type and no variation of the coeficcient in vertical direction indicating potentiality of Au ore at depth. |
