本文介绍一种简便的求磁化强度矢量的方法,即由野外观测到的地磁场,经过化极(一般是化为垂直磁化),根据磁异常强度的极值及异常特征,用查表的方法求得磁化强度的倾角和方向,剩磁和感磁数值,这样就可以用于评价磁性地质体的性质与产状。本方法主要用于大面积开展磁法普查以及区域性航空磁测,在作面积性的初步解释推断时,可以免除广泛对各类磁异常进行实地特性采样和测定,能使在较短时间内对面上分布各类磁异常取得磁化强度参数,进而开展对全区磁异常的推断和评价,以加速对异常研究的进程。
In this paper, we introduce a simple method to find the magnetization vector, that is, the geomagnetic field observed from the field passes through the pole (usually into a perpendicular magnetization). According to the extreme value and anomaly of the magnetic anomaly intensity, Obtain the inclination and direction of magnetization, remanence and magnetic susceptibility values, which can be used to evaluate the nature and appearance of magnetic geology. The method is mainly used for carrying out large-scale magnetic survey and regional aviation magnetic surveying. When making preliminary explanations and inferences based on area, the method can be exempted from extensively sampling and determining various types of magnetic anomalies in the field and enabling the measurement in a relatively short period of time Opposite the distribution of various types of magnetic anomalies to obtain the magnetization parameters, and then carry out the region’s magnetic anomalies inferred and evaluated to accelerate the process of anomalous research.
