| 摘 要： | 内蒙古西乌珠穆沁旗布敦乌拉矿区多为第四系覆盖。在该矿区多金属勘查中,依据土壤地球化学圈定的矿化异常布置激电中梯测量,圈定1处激发极化率异常区,长度约890m,宽度约520m,位于已知断层F 1与推断断层F 2之间。采用可控源音频大地电磁测深剖面对该激电异常进行探测,解释视充电率多峰异常与反演电阻率高低跳跃对应区域为矿致异常区。通过钻探验证,发现银多金属矿床资源储量523.93万t,取得了良好的地质找矿效果。

| Abstract: | The most parts of Budun Ul mining area in the Xi Ujimqin Banner,Inner Mongolia is covered by Quaternary System.During the polymetallic ore exploration in the mining area,based on geochemical soil survey delineated mineralization anomalies have laid out IP intermediate gradient area survey and delineated one IP polarizability anomalous zone with about 890m long and 520m wide,situated between known fault F 1 and deduced fault F 2.Using CSAMT sounding section has carried out detection for IP anomalies.Interpreted apparent chargeability multi-peak anomalies and inversion resistivity peak saltation corresponding regions are ore resulting anomalous regions.Through drilling verifications have found silver polymetallic ore resource reserves 5.2393 million tons and achieved favorable geological prospecting effects. |
