| 中文摘要: |
| 利用地面高精度磁测，对第四系大面积覆盖的研究区，开展了磁铁矿的综合方法找矿。对磁场观测数据进行了不同高度的上下延拓磁异常计算处理，并据磁异常分布特征和磁参数物性情况及地质情况，圈定了区内磁异常8个，当正磁异常值大于500nT时，推测为矿致磁异常引起。据正磁异常的分布特征，在C1正磁异常区和其它正磁异常区，布置了数孔进行钻探验证，仅个别钻孔未见到磁铁矿，取得了物探方法地面磁法直接找矿的成功实例，为它区相同地质背景寻找磁铁矿提供了经验。 |
| 英文摘要: |
| By surface high-precision magnetic survey, magnetite is explored in the target area where large Quaternary system covered. The up and down continuation magnetic anomaly magnetic survey data of different height are calculated, according to the magnetic anomaly distribution features, magnetic parameter physical property and geologic condition, 8 magnetic anomaly in this area are determined. When the value is more than 500 nT, it’s inferred it caused by magnetic anomaly. According to the normal magnetic distribution, some drills are arranged to test in the C1 normal magnetic anomaly area and other normal magnetic anomaly area. The magnetite was not found only in few drilling holes, the successful example is gotten which exploration by surface magnetic method, affords experience for other area with the same geologic background. |
