Reduction to the Pole and Analytic Signal Interpretation Techniques of Magnetic Data in Equatorial Area, Ethiopia

Lingerew Nebere

Abstract: Magnetic data interpretation in equatorial area is a very difficult task due to low intensity and direction of the inducing field. As a result the anomaly produced by such weak inducing field is not visible (low amplitude) unless appropriate enhancement techniques are applied. To minimize the effect of magnetization direction, analytic signal method was applied while; to increase the amplitude of the intensity and to transform dipole to monopole the reduction to the pole techniques were used.
