摘　　要：龙湾铅锌矿是桂东南佛子冲矿田的典型矿床,近几年的深部找矿取得重大突破。龙湾铅锌矿为接触交代型和构造热液充填型矿床,主要控矿因素为岩性、构造、花岗斑岩脉和变质作用,有利成矿部位主要是花岗斑岩脉边界、背斜核部虚脱部位及其附近的断裂构造。通过对龙湾铅锌矿床成矿地质特征的分析,深部找矿思路的总结,找矿手段的探索,探讨成矿规律及控矿因素,并对佛子冲矿田深部找矿提出思路和建议。Longwan Pb-Zn deposit is a typical deposit of Fozichong ore field in southeast Guangxi.Great breakthrough has been made in deep prospecting in recent years.Longwan Pb-Zn deposit is a contact metasomatic and tectonic hydrothermal filling deposit.The ore controlling factors are lithology,structure,granite-porphyry vein and metamorphism.The favorable metallogenic sites are granite-porphyry vein surface,collapse site of anticlinal core and fault structure nearby.Based on the analysis of metallogenic geological characteristics of the Longwan Pb-Zn deposit,the summary of deep prospecting ideas,the exploration of prospecting means,the metallogenic regularity and ore-controlling factors are discussed,and the ideas and suggestions for deep prospecting in Fozichong ore field are put forward.
