Effect of magnetic field direction and source orientation on depth estimation solutions

Most semi-automated processing routines assume simple scenarios where the resultant anomaly is produced by a single, parallel-piped, non-dipping source in a vertical ambient field. This however does not represent any realworld situation. All magnetic sources will have some dip and not be oriented parallel or orthogonal to the ambient magnetic field. Therefore, the angle at which the magnetic field intercepts the source will not be the same …
