摘　　要：研究区位于我国重要的金、铜、铅、锌等多金属成矿区,在分析研究区地质、物化探特征的基础上对研究区资源潜力进行评价。研究区矿化程度较低,加之深部没有控制。首先应加强区域性构造的研究,研究区域构造格架,建立区域构造体系,对控矿构造进行理定。采用构造地质法、原生晕地球化学方法、高密度电法测量等综合方法进行研究区资源潜力的评价。认为加疙瘩研究区内露出的地层自老到新分别为:上元古界加疙瘩群,及古生界寒武系、中生界侏罗系及新生界第四系;区域内主要为海西期斑状花岗岩;区内北东、北北东、北西向断裂、褶皱构造发育。矿化脉体主要受北西向构造角砾岩带控制,倾向南西,倾角70°左右,认为研究区沿北西向构造带分布的构造角砾岩是矿区最重要最直接的找矿标志。The study was carried out in one domestic important polymetallic(including gold,copper,lead,zinc and so on)metallogenic region.In this area,we not only did the geological,geophysical and geochemical exploration characteristics study,but also did the resource potentiality evaluation.Mineralization degree of study area is low without control in deep part.First,we should focus on study of regional structure and regional tectonic framework,we should establish regional structure system,and we should process the orecontrolling structure.We did the resource potentiality evaluation by using of geological structure method,primary halo geochemical method,high-density electrical method and the other comprehensive methods.We think the stratum of the Jiageda study area from old to new are:Proterozoic Jiageda groups,paleozoic Cambrian,Mesozoic Jurassic and quaternary system in the new territories;Hercynain porphyritic granite is mainly existed inside the study area:north-east,north-north east,north wast fracture,fold structure and development.The mineralized veins are mainly controlled by north-wast tectonic breccia belt,west-south trend,the dip angle is about 70°,we thought the most direct prospecting criteria is the tectonic breccia along with the north-west tectonic zone of the study area.
