Determinations of the depth of magnetization and density contrasts in the earth's crust can be made by a statistical analysis of the regional geomagnetic anomalies and from the regional Bouguer anomalies. For this purpose, the conditions in the crust are represented by a statistical model, the most important parameters of which can be determined by the analysis. Magnetization and density contrasts are simulated by random distributions of magnetic dipoles or mass-points at the corresponding depth. On the basis of autocorrelation functions for the measured field and for the field of the specific model the determination of depth is performed. An error estimation reveals depth errors of about 15 to 20%. The application of the described method on the observations of the magnetic ΔZ-anomalies and the Bouguer anomalies in the area of the G.D.R. yields three magnetization contrasts at an average depth of 9, 14, and 20 km, and two density contrasts at a depth of 5 and 13 km.
