Magnetic transforms of modulus type applied at region of lower latitudes in SE China

Abstract

Reduced to the pole is a problem that seriously affects the accuracy of aeromagnetic exploration in low-latitude regions. To eliminate the reduced to the pole effect, we proposed a transform modulus of the magnetic anomaly. This method has been used to process aero magnetic data in a low-latitude region, i.e., the eastern region of Jiangxi, China. The calculated result of the transform modulus is not significantly affected by the magnetization direction. Results clearly indicated anomaly shape, size, and location. The magnetic anomaly conversion modulus showed good effects on regional aeromagnetic data processing at low latitudes.
