摘　　要：通过对陕西葫芦沟金矿部分微量元素与烃类组分在不同中段的含量变化及在矿体周围的异常展布特征和富集规律的分析和总结,得出该矿床原生晕分带序列为:甲烷、乙烷、丙烷、Zn、As、Ag、Sb(矿前晕)→Ag、Ni、Mn、异丁烷、正丁烷、乙烯、丙烯(矿头晕)→Hg、Pb、Ag、Au(矿中晕)→Co(矿尾晕),建立了矿床地质—地球化学找矿理想异常分带模型,并总结了找矿标志,为其深部以及外围地区的找矿预测评价提供了科学依据。The content changes of partial trace elements and hydrocarbon components in different mid-section and its abnormal distribution characteristics and enrichment regularity around ore body of Hulugou Gold Deposit were analyzed and summarized, obtaining the primary halo zoning sequence of the deposit： methane, ethane, propane, Zn, As, Ag, Sb（front halos）→Ag, Ni, Mn, isobutane, n-butane, ethylene, propylene（ore roof halos） →Hg, Pb, Ag, Au（ore centre halos） →Co（ore tail halos）. An ideal model diagram of prospecting geochemical anomaly zoning was established, and the prospecting indicators were summarized, providing a scientific basis for prospecting and evaluation of deep and peripheral areas.
