中文摘要:
      扎拉格阿木铜多金属矿是近年来内蒙古中西部铜矿勘查的一个重要突破。矿体赋存在哲斯组与花岗闪长岩的外接触带,赋矿层位为哲斯组含碳质板岩及砂板岩。该矿是在对面积很小的1︰5万土壤异常查证时发现的。地球物理特征为高极化率异常的梯度带,相对低(中)的视电阻率,高重力异常区,北东向平稳磁场带中孤岛状小规模高磁异常的北侧。研究表明:0线的AMT-O-1、AMT-0-2异常为下步深部勘查的重点预测区,激电IP1-5、IP1-4及地磁C2异常区为外围找矿的重点预测区。音频大地电磁测深圈定出的异常与已知见矿部位对应良好,配合激电和重力测量成果,是该区有效的物探方法组合,对下一步深部和外围找矿有较好的指导意义。
英文摘要:
      Zhalageamu copper polymetallic deposit gets an important breakthrough in finding copper deposits of midwestern Inner Mongolia recently years. The ore body is deposited in the outer contact zone of the Zhesi group and the granodiorite, and the ore layer is the carbonaceous slate and sand slate. The deposit was found when a small area of 1/50000 soil abnormality was checked.The geophysical characteristics are the gradient area with high polarization anomaly, the relatively low (middle) apparent resistivity, the high gravity anomaly area, and the location is the north side of the isolated island’s small high magnetic anomaly in the north east to the stationary magnetic field.The study shows that AMT-0-1 and AMT-0-1 anomalies of 0 line are the key predictive areas for the deep exploration in the next stage. IP1-5、IP1-4 and C2 magnetic anomalies are the key predictive areas for the the periphery prospecting. The AMT anomaly, corresponding well to the known mine part, together with the IP and gravity measurement results, are the effective combination of geophysical exploration methods, which have better guiding significance for the deep and periphery prospecting.
