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
