Use of higher derivatives of the magnetic potential in magnetic prospecting
Abstract
The use of the higher derivatives of the magnetic potential to calculate the depth and other elements of occurrence from complex magnetic anomalies indicating the presence of a number of disconnected bodies with the same magnetization or rocks with changing magnetization provides a number of advantages over the methods of calculations directly from Z or ∆T curves: 1) the possibility of dissecting complex curves depicting the total field of a number of magnetized bodies; 2) a sharp reduction or complete elimination of the dependence of the problem solution on errors in the choice of the normal field; 3) the ability to calculate the total field of a number of magnetized bodies.
