| 摘 要： | 采用高精度磁法、激电和重力方法相结合的方式对那西郭勒沉积变质型铁、石墨矿区进行地球物理勘查评价,圈定多个高磁、低阻高极化率异常区,经工程验证该异常由多个铁、石墨矿体引起,铁矿体主要赋存于石英片岩和大理岩中,石墨矿体主要赋存于大理岩内,成因类型为沉积变质型,矿床规模为中型。研究结果表明,高精度磁法与激电的联合应用,可以快速圈定铁石墨矿化异常体,并为后期探矿工程部署提供依据,是寻找同类型矿床的有效方法之一。

| Abstract: | Geophysical exploration evaluation is applied in the Naxiguole sedimentary metamorphic type iron-graphite deposit by using high precision magnetic method, IP and gravity method.Many multiple high magnetic, low resistance and high charge ability anomalies has been delineationed which caused by multiple irons, graphite ore bodies. Iron ore bodies mainly occur in quartz schist and marble while graphite ore bodies occur mainly in marble. The genetic type of the deposit is sedimentary metamorphic type with medium size. The results show that the combined application of high precision magnetic method and IP can quickly identify areas of graphite iron mineralization abnormal bodies, and provide the basis for later exploration deployment, and is one of the effective methods to find same type deposit. |
