... the interpretation of the magnetic data and lead to erroneous size or shape. Therefore, it is imperative to know the total magnetization direction. We propose a method that is based upon the optimal correlation between two tools in magnetic data interpretation: the vertical gradient and the total gradient of the RTP...

... Summary Unlike the 2D case, the total gradient (magnitude of the gradient vector) in 3D is not the envelope of either the vertical or horizontal derivatives of the total-field anomaly over all possible directions of the earth''s field and source magnetization. Instead, the total gradient...
