摘　　要：通过对龙口铅锌矿床各微量元素与烃类组分在不同中段的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Hg、甲烷、乙烷、丙烷、异丁烷、正丁烷、乙烯、丙烯(矿前缘)→As、Sb(矿头)→Ag、Cu、Pb、Zn(矿中)→Mo、Co、Ni(矿尾),建立了矿床的地球化学异常分带模型,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。Through the analysis and summary of the content changes of all the trace elements and hydrocarbon components in different middle part of Longkou lead-zinc deposit,and the enrichment law and abnormal characteristics of the surroundings ore body,it concludes that the zoning sequence of primary halo can be classified as follows： the mine front is Hg,methane,ethane,propane,isobutane,n-butane,ethylene,propylene,the head is As,Sb,the middle is Ag,Cu,Pb,Zn,and the trail is Mo,Co,Ni.The geochemical anomaly zoning model is established and the prospecting guides are summarized to provide the scientific basis for prospecting prediction evaluation in the deep and peripheral area.
