摘要
野外岩、矿石物性测定表明,矿区内铁矿石磁化强度高,而围岩磁性相对磁铁矿较弱,这为在矿区进行高精度磁测提供了可靠地地球物理依据。本次工作在研究区进行了地面高精度磁法测量,探测地下铁矿化因此的磁异常,并结合地质资料,对潜覆盖区和矿区深部矿体进行反演,取得了较好的成果。
Physical property test of the rocks and ores in the field shows that the iron ore has a high- strong magnetic properties, while the normal rock are micro or weak magnetic compare with the iron ores, which provides a reliable basis of geophysicist to carry out ground high-precision magnetic survey in the mining area. The research work in the area is to detect the measurement,and to conduct magnetic anomaly inversion for under ground ore body. Compared with geological and drilling data, the obtained results are good.
