摘　　要：蒙山岩体岩体出露面积约39平方千米,周边金属元素土壤地球化学异常明显,地表出露多处矽卡岩型金属矿化体;马湖金多金属矿区出露蒙山岩体,具有良好的寻找铜多金属矿的前景,马湖矿区开展了1∶2.5万土壤地球化学测量27 平方千米,采集土壤地球化学样品2030件。经对样品元素地球化学数据处理,统计了矿区地球化学特征及元素分布特征和地球化学场,通过异常圈定、异常分类、异常评序、异常剖析等过程,圈定了以铜、铅、锌、银、金元素为综合异常,结合矿区地质特征,对综合异常综合分析,提出该矿区具有找矿意义的铜多金属矿找矿靶区四处,为矿区下步找矿指出了方向。The Mengshan pluton outcrops an area of about 49 square kilometers,with obvious soil geochemical anomalies of metal elements around it.There are also several siliceous rock-type metal mineralization bodies exposed on the surface.The Malu gold-multi-metal mine is located 2 kilometers west of the Mengshan pluton.In the Malu mining area,a 1:2.50,000 soil geochemical survey covering an area of 27 square kilometers was conducted,and 2030 soil geochemical samples were collected.After processing the element geochemical data of the samples,the geochemical characteristics and element distribution characteristics of the mining area,as well as the geochemical field,were statistically analyzed.Through the process of anomaly delineation,anomaly classification,anomaly ranking,and anomaly analysis,four comprehensive anomalieswere delineated,which are rich in copper,lead,zinc,silver,and gold elements.Combined with the geological characteristics of the mining area,a comprehensive analysis of the comprehensive anomalies was conducted,and three targets for copper-multi-metal mineral explorationwere proposed,which provide direction for the next phase of mineral exploration in the mining area..
