摘　　要：为研究陕西省双王金矿床的物质组分,对矿物进行反光显微镜观察和电子探针分析,发现了自然金、自然铋的金属矿物以及黑铋金矿的金属互化物。这些自然金属矿物与金属互化物在卡林型、类卡林型金矿床中均有较罕见的产出,其生成条件独特,是在一种缺氧、低硫的较强还原环境中形成的,反映出成矿作用与岩浆活动有密切联系。To study the substance composition of Shuangwang gold deposit in Shaanxi province,the ores was analyzed by optical microscope and EPMA and found the native gold,native bismuth,and maldonite.These natural metal minerals and metal intermetallics are relatively rare in Carlin type and Carlin type gold deposits.Their formation conditions are unique.They are formed in a strong reduction environment without oxygen and low sulfur,reflecting close relation with magmatic activities.

关 键 词：自然金属 金属互化物 双王金矿床 陕西省
