摘要/Abstract

摘要： 从泊松定理出发进行公式推导和分析，阐述了重磁异常的对应分析3个参数的物理意义，并认为在区域重磁数据解释时，对应分析得到的截距是在去掉感磁背景和与重力异常线性相关部分异常的剩磁异常的贡献，为其应用提供了基础。分析了重磁异常解释中泊松定理的作用，并通过具体的实例分析了基于泊松定理来确定地质体总磁化方向及其在分析火山岩活动中的作用。

关键词: 重磁异常, 泊松定理, 对应分析, 磁化方向

Abstract: The authors expatiate the physical meanings of three parameters of CA (corresponding analysis) of gravity and magnetic anomalies according to the formula deduction and the result analysis from Poisson’s theorem. The intercept of CA in interpretations of regional gravity and magnetic anomalies should only be the contribution of remanence anomalies, which can be obtained by total anomalies subtracting induced magnetism background and gravity anomalies related parts. The cases studies of hide geological body and lava activity show that this Poisson’s theorem based method has very good prospective in regional geophysical interpretation.

Key words: gravity and magnetic anomalies, Poisson’s theorem, CA (corresponding analysis), magnetizied direction
