摘　　要：太仆寺旗超格温多尔地区金多金属矿为中温热液裂隙充填型矿床,成矿与本区断裂构造及岩浆活动密切相关。依据该区1∶1万激电中梯测量,共圈出低阻高极化异常4处。通过对典型异常DJ1与DJ3的物理解释、地质分析及钻孔验证,总结出该区金多金属矿成矿特点,以此确定了找矿标志与方向:①岩石蚀变矿化部位;②Pb、Zn、Ag、Cu等多金属元素地化综合异常带;③激电中梯测量呈低阻高极化异常区;也是多金属矿床的重要找矿标志。④区内正、负地磁异常转换区;⑤韧性剪切断裂带。邻近矿床与本区在构造、岩浆活动期次、围岩蚀变、赋矿岩石及成矿类型具有高度相似性,其研究成果为钻探设计提供了依据。The Au polymetallic deposit in the Zogondor area,Taibus Banner is a mesothermal fissure-filling deposit,the ore-forming process is closely related with faulted structures and magmatic activities in the area.Based on 1:10,000 IP intermediate gradient survey has delineated 4 low-resistivity high polarization anomalies.Through physical interpretation,geological analysis and drilling verification for typical anomalies DJ1 and DJ3 have summarized polymetallic deposit ore-forming features in the area,based on the results have defined prospecting criteria and orientation.The criteria have:1)rock altered metallization position;2)Pb,Zn,Ag,Cu polymetallic elements geochemical integrated anomalous zone;3)IP intermediate gradient survey presented low-resistivity high polarization anomalous region,also the polymetallic deposit important prospecting criterion;4)study area positive and negative geomagnetic anomalies transitional region;5)ductile shear fracture zone.Neighboring ore deposits and the study area have high degree of similarity on structures,magmatic activity stages,surrounding rock alterations,ore-bearing rocks and metallogenic types,thus the studied results have provided the basis for drilling design.
