在磁异常处理及解释推断中,磁化方向是个必不可少的参数。为了便于直接根据实测的地球物理场信息,计算磁性体的有效磁化倾角,本文提出了利用磁异常与其半和(半差)曲线的相似系数、磁异常与电磁异常的相似系数、磁异常与重力异常一阶导数的相似系数确定磁性体有效磁化倾角的三种不同方法。后两种方法不受水平二度磁性体截面形状、产状的限制,适合ΔT、Za、Ha各分量与重力、电磁异常的综合解释。
In magnetic anomaly processing and interpretation inference, the direction of magnetization is an indispensable parameter. In order to calculate the effective magnetization dip angle of the magnetic body directly from the measured geophysical field information, this paper proposes the use of the similarity coefficient between the magnetic anomaly and its semi-sum (semi-difference) curve, the similarity coefficient between the magnetic anomaly and the electromagnetic anomaly, the magnetic anomaly and the gravity Similarities of Abnormal First Derivatives Three different ways of determining the effective magnetization dip of a magnetic body. The latter two methods are not limited by the cross-sectional shape and shape of the horizontal second-degree magnetic body and are suitable for the comprehensive explanation of the components of ΔT, Za and Ha and the gravity and electromagnetic anomalies.
