前言早在1951年,就认识到剩余磁化强度对岩体的磁异常有影响.后来研究结果证明,在测定的地质体磁异常中,剩余磁化强度可以超过感应磁化强度.古地磁测定岩体剩余磁化强度常用的方法,包括在野外采集岩石标本和在室内测定标本的磁化方向.可是在海丘研究中,有些作者指出,其磁化方向可以根据磁异常与测深法所测得的海丘形状和位置进行对比来确定.本文目的在于证明,可以根据地质体重,磁异常的空间关系来确定其磁化方向,从而获
Preface As early as 1951, it was recognized that residual magnetization had an impact on the magnetic anomaly of rock mass.According to the results of the research, it is proved that the remanent magnetization can exceed the induced magnetization in the measured geomagnetic anomalies. Magnetization commonly used methods include the collection of rock specimens in the field and the determination of the magnetization direction of the specimens indoors.However, in the study of the seabed, some authors point out that the magnetization direction can be determined according to the shape of the hierroasia measured by magnetic anomaly and sounding And the location of the comparison to determine the purpose of this paper is to prove that according to geological weight, magnetic anomalies to determine the spatial relationship between the magnetization direction, which won
