| 摘 要： | 在普查磁性矿床时,当测区内岩石磁性较强的情况下,区分磁异常的性质是一个重要课题。本文通过已知磁铁矿床区和磁性岩体区的电磁法测量,利用磁偶源测得的二次磁场垂直分量和由电偶源测量得到波阻抗,分别求取了磁性矿体和磁性岩体的相对磁导率,以此来区分磁异常的性质。

| Abstract: | It is an important subject to discriminate the nature of magnetic anomaly in general survey of magnetic ore deposit in case of strong magnetic rocks. This paper, based on EM survey in known magnetite ore deposit area and magnetic rock body area, made use of vertical component of secondary magnetic field measured from magnetic dipole source, and of wave impedance measured from electric dipole source, to calculate relative magnetoconductivity of magnetic ore body and magnetic rock body, thus to distinguish the nature of magnetic anomaly. |
