P230 A TECHNIQUE FOR INVERSION OF 2D MAGNETIC ANOMALIES REPRESENTED BY THEIR MAGNITUDES P.Y. STAVREV University of Mining and Geology “St. Ivan Rilski” Department of Applied Geophysics 1700 Sofia Bulgaria 1 SUMMARY The analytic expressions of a magnetic anomalous field represented by its vector magnitudes and their gradient and Laplacian reveal opportunities for an effective depth and shape inversion in terms of model sources widely used in the first stage of data interpretation. An estimate of the depth of a source causing magnetic field of one singular point can be obtained directly without assumptions about the source’s shape and vector
