建立了电感耦合等离子体发射光谱（ICP－AES）与原子荧光光谱（AFS）联合测定金矿地质样品中32种主、次、微痕量元素的方法。样品分别采用HNO3－HF－HClO4－H3 PO4和KOH及含酒石酸的王水分解，ICP－AES依次测定主量元素Si、Al、Ca、Mg、Fe、P，较高含量元素Mo、Sn、W，以及Ag、As、B、Ba、Be、Bi、Ce、Co、Cr、Cu、K、Mn、Na、Sb、Sr、Ti、Ni、Pb、V、Zn等；AFS依次测定微痕量Hg和Se、Te。该方法应用于金矿地质样品和多金属国家标准样品分析，测定结果与推荐值吻合，精密度（ RSD）小于10％，为金矿地质样品化学组成和多金属矿床成矿环境、成因机制的研究以及矿产资源的综合利用等，提供了充分的依据。
