摘　　要：五道沟地区位于黑龙江省贺根山—黑河构造结合带的北缘,多宝山至三道湾子成矿带的中部,该区域成矿潜力巨大,是寻找金铜多金属矿的有利地区。为在五道沟地区实现找矿突破开展了地质找矿工作,并以1∶1万土壤地球化学测量数据为基础,采用元素的变化系数、CV1和CV1/CV2变化系数解释图对土壤地球化学测量的元素进行分析,揭示各元素在空间上的富集分布规律及其成矿潜力。在此基础上,结合区内成矿地质条件和物探异常特征对该区进行找矿预测。研究表明:①Cu、Ag、Zn、Mo、W等9种元素在研究区内成矿潜力较小;Au元素成矿潜力较大。②据物探激电中梯测量显示,在研究区内共圈定2处电阻率异常,其编号为ρs-1、ρs-2。③根据地质-物探-化探异常套合关系在区内圈定了1处找矿靶区,经过对1号靶区进行工程验证发现了3条金矿体,表明五道沟地区具有较好的找矿前景。Wudaogou area is located in the northern margin of the Hegenshan-Heihe tectonic junction zone in Heilongjiang Province,and in the middle of the Duobaoshan-Sandaowanzi metallogenic belt.It has great metallogenic potential and is a favorable area for prospecting for Au-Cu polymetallic deposits.In order to achieve a breakthrough in prospecting in Wudaogou area,geological prospecting work was carried out.Based on 1∶10,000 soil geochemical survey data,the elements of the soil geochemical survey were analyzed by using the variation coefficients of elements,CV1 and CV1/CV2 variation coefficients interpretation maps,and the spatial enrichment and distribution of elements and their mineralization potential were revealed.On this basis,combined with the metallogenic geological conditions and geophysical anomaly characteristics,the prospecting prediction in this area was carried out.The results of the study showed that;①the metallogenic potential of nine elements,such as Cu,Ag,Zn,Mo and W,was relatively small in the study area,while that of Au was relatively large.②According to the elevator survey of IP in geophysical prospecting,two resistivity anomalies were delineated in the study area,numbered asρs-1 andρs-2.③A prospecting target area had been delineated in the area according to the geological-geophysical-geochemical anomaly matching relationship.Three gold orebodies have been found through engineering verification of target area 1,which indicates that Wudaogou area has good prospecting prospects.
