摘要
八卦庙金矿床是秦岭造山带的一种与深源热水喷流、岩浆热流体有关的中温热液矿床。本文系统总结了该矿床的微量元素地球化学特征，对矿石、钠长岩、钠长板岩、层间石英脉、节理石英脉和岩脉等能反映成矿流体作用痕迹的岩石进行微量元素测试，作相关分析。结合其它有关证据论证了八卦庙金矿成矿在物源上既继承了热水喷流的物质，又吸收了岩浆提供的物质。该矿床的富集成矿是岩浆热流和期后热流体动热改造的结果。
The Baguamiao gold deposit is a mesohermal gold deposit genetically related to deep-seated thermal exhalation and magmatic fluids. The characteristics of trace elements are summarized. The ores, albitite, albite slate , quartz veins and dykes are sampled for analysis of trace elements. The above-mentioned research work indicates that the deposit inherits from thermal fluid exhalation in ore-forming materials, and magmatic process provides some ore materials. The mineralization is resulted from magmatic fluid process and postmagmatic fluid reformation.
