不同物探方法在锡林郭勒盟多金属矿勘查中的应用

Application of Different Geophysical Prospecting Methods in the Exploration of Polymetallic Ores in Xilingol League

锡林郭勒盟位于内蒙古自治区中部,是我国铜铅锌矿的主要产地,地表发现的露头及化探异常也充分印证铜铅锌矿的存在。但是,发现的矿脉及化探异常是否向深部延伸,延伸多深都是未知数。因此,本研究主要针对矿脉及化探异常周边位置,开展激电测深及可控源大地电磁测深工作,了解深部构造破碎带及矿化蚀变的埋深、倾向等地质信息,综合多种方法进行分析和推断,为地质钻探提供最优找矿靶区,并为类似地区开展地质找矿提供参考。

Xilingol League is located in the central part of Inner Mongolia Autonomous Region and is the main production area of copper-lead-zinc ores in China,and the outcrops and geochemical anomalies found on the surface also fully confirm the existence of copper-lead-zinc ores.However,it is unknown whether the discovered ore veins and geochemical anomalies extend deeper and how deep they extend.Therefore,this study mainly focuses on the surrounding locations of ore veins and geochemical anomalies,and conducts induced polarization sounding and controllable source magnetotelluric sounding to understand geological information such as the burial depth and dip of deep structural fracture zones and mineralization alteration,and integrates multiple methods for analysis and inference,thus providing the optimal target area for geological drilling and exploration,and providing reference for geological exploration in similar areas.
