| 摘 要： | 内蒙古海力敏萤石矿属热液脉型,萤石—石英矿受花岗岩体内NW向断裂破碎带控制。矿区开展了甚低频电磁法找矿勘查研究,在已知矿体上测得明显的甚低频电磁异常,证实了该方法对寻找此类萤石矿床的有效性。在不易识别开采的掩盖区,所测甚低频电磁异常显示控矿断裂带仍存在,极可能赋存萤石矿体。

| Abstract: | The Hailimin fluorite deposit in Inner Mongolia is of hydrothermal vein type, whose fluorite quartz orebodies are controlled by a NW trending faulted zone. The very low frequency electromagnetic method (VLF EM) was used to conduct ore prospecting studies in the ore district. As a result, distinct very low frequency electomagnetic anomalies were detected over the known orebodies, which proves the effectiveness of this method in search for such type of fluorite deposits. In the concealed area, the very low frequency electromagnetic anomaly reveals that the ore controlling faulted zone remains existent, which is likely to contain fluorite orebodies. |
