摘　　要：在硫化矿床氧化成铁帽的过程中,亲铁元素发生明显分离。相对分离程度与表生金的迁移富集密切相关。据此建立了Fe/Mn、Fe/Ni、Co/Ni比值与矿石样品Au含量的相关数学模型,为利用地球化学特征勘查金矿提供了更高层次的找矿信息。During the oxidation of sulfide deposit into gossan,a distinct separtaion of siderophile elementsis happened,and the relative degree of separation is closely related to the migration and enrichment ofsupergene gold.For this reason,a mathematical model showing the correlation between element ratios(Fe/Mn,Fe/Ni,and Co/Ni) and gold contents of ore samples is established.It provides more usefulinformation for gold prospecting by making use cf geochemical features.
