Abstract

The present invention relates to a method for locating magnetic bodies within the earth and in particular to a method for determining the subsurface location, geometry and depth of these bodies from aeromagnetic data. The method includes accessing aeromagnetic data and processing the data according to the described equations to determine the subsurface location, geometry and depth of these bodies.
