根据详细对比磁铁石英岩铁矿层的地质参数和有关的地球物理参数所得的结果,可作出如下的初步解释:1.单是余磁即可在磁铁石英岩铁矿层上引起强大异常.它是所获得的异常的主要部分.余磁强度为感磁强度的六倍多.2.垂直磁场强度测量不能用来查明含矿最高的地带,因为在变质铁矿中余磁强度也大.3.一般余磁方向是沿层理面的,并与褶曲构造和矿石线理的倾向平行.4.垂直磁力梯度测量对寻找隐伏的铁矿层与石英黑云母片岩的接触带是有效的,它还可以反映主矿层中磁铁矿含量的变化.5.在现场进行磁化率半定量测量,可测得铁矿层中百分之几的磁铁矿含量.当换算成含铁重量百分数时,所得结果表明铁矿层的含铁品位在20～50%范围内.6.水平线框的电磁法没有提供有结论意义的结果;主矿带上有虚分量异常,而另一些矿带上则没有异常.7.在铁矿层上和片岩上平行层理测得的地震波速度都有规律地由西到东增大,地震波速度似乎随着岩石变形程度的增大而增大.
According to the detailed comparison of the geologic parameters of the magnetite-quartzite and the related geophysical parameters, the following preliminary explanations can be made: 1. The residual magnetism can cause a strong anomaly on the magnetite-quartzite iron ore layer. Is the main part of the anomaly obtained.Individual magnetic intensity is more than six times of the magnetosensitive strength.2.Vertical magnetic field strength measurement can not be used to identify the highest ore-bearing area, because the remanent iron in the metamorphic iron ore is also large. 3. The general magnetic direction is along the bedding plane and parallel to the tendency of the fold structure and the ore line.4 Vertical magnetic gradient measurement is effective in finding the contact zone between the concealed iron ore layer and quartz biotite schist, It can also reflect changes in the magnetite content in the main seam.5.Semi-quantitative measurements of susceptibility in the field can be used to determine the percentage of magnetite in the iron ore layer.When converted to the weight percentage of iron , The results show that the iron ore grade is in the range of 20-50% .6 The horizontal wireframe electromagnetism method does not provide the conclusion that the conclusion is significant. On the main ore belt there is an imaginary component anomaly, while on the other ore belts No abnormalities .7. Parallel layers on iron ore and schist The measured seismic wave velocities regularly increase from west to east, and the seismic wave velocity seems to increase with the degree of rock deformation.
