摘　　要：百定金矿位于广西田东县北部,为与辉绿岩类关系密切的微细粒浸染型金矿床,在桂西地区亦被称为辉绿岩型金矿床。针对本区的成矿规律和找矿方向前期研究较少,通过研究百定金矿区的矿床地质、地球化学异常及围岩蚀变等特征,分析控矿因素、矿床成因以及找矿前景。研究结果表明,构造对金矿的控制作用表现为褶皱与断裂构造的组合控矿,矿区处于“背斜加一刀”的有利成矿构造空间;金矿床的形成经历了主成矿期(热液期)和表生期;矿区找矿潜力较大,并提出3个找矿靶区。研究成果为下一步金矿找矿工作指明了方向。Baiding gold deposit,located in the north of Tiandong County,Guangxi,is a fine disseminated gold deposit closely related to diabase,which is also called diabase-type gold deposit in West Guangxi.For the lack of previous research on the metallogenic regularity and prospecting direction in this area,the geological characteristics of the deposit,geochemical anomaly and wall rock alteration are analyzed and the ore-controlling factor,deposit genesis and prospecting prospect are summarized in the Baiding gold mining area.The research result indicates that the controlling effect of structure on gold deposit is manifested as a combination of fold and fault structures,and the mining area is in a favorable ore-forming structural space of"anticline plus one knife".The formation period of gold deposit is divided into the main mineralization stage(hydrothermal stage)and epigenetic stage.There is a great potential for mineral exploration in the mining area,and three target areas have been proposed for mineral exploration.The research result has pointed out the direction for the next step of gold exploration work.
