沿航磁剖面测得的异常,一般是由基底磁性变化引起的。不过,某些强度较弱的异常往往来源于浅部。用高灵敏度磁力仪能够很容易地发现这类异常,因而也就增大了其重要性。当同一剖面上存在有这类异常时,如果能把它们区分开,以便对每个异常更好地加以研究,将是很有意义的。用图解法能够达到分开这两种异常的目的。如果灵活熟炼地使用图解法,可以得到 Abnormalities measured along the magnetic profile are generally caused by magnetic changes in the substrate. However, some weaker anomalies tend to come from the shallow. This type of anomaly can easily be detected with a highly sensitive magnetometer, thus increasing its importance. When such anomalies exist on the same section, it would be significant to be able to distinguish them so that each anomaly can be better studied. With the graphic method to achieve the purpose of separating these two kinds of anomalies. If you use the graphic method flexibly, you can get
