中文摘要:
      为了了解太阳沟钼矿区成矿情况,采用SQ-5双频道轻便型数字激电仪,通过频率域激发极化中间梯度法进行扫面和精测剖面测量,圈定了低阻高极化重点异常区。为进一步了解激电异常的垂向分布及变化情况,选择成矿有利地段进行激电测深测量,测量结果显示太阳沟岩体及其接触带深部存在相对低阻高极化异常。钻孔验证结果表明,深部见矿较好区域与极化率高值区及电阻率低值区吻合良好。综合分析认为,矿区具有较好的成矿前景,激发极化法对该区进一步找矿评价工作有着积极的指导意义。
英文摘要:
      In order to master the metallogenic condition of Taiyanggou Molybdenum Deposit, a dual-channel portable digital IP instrument SQ-5 was used to delineate the low-resistance and high-polarization key abnormal areas by means of the intermediate gradient method of induced polarization in frequency domain. In order to know more about the vertical distribution and variation of Ip anomalies, induced polarization sounding is carried out in the favorable ore-forming area. The drilling verification results show that the better ore-finding area in the deep is in good agreement with the high value of polarization rate and the low value of resistivity. Based on the comprehensive analysis, it is concluded that the ore-forming area has a good ore-forming prospect, and the induced polarization method has a positive guiding significance for further ore-prospecting and evaluation in this area.
