Upper panel shows data for a cube model with the vertical magnetization of the inducing field. The smooth images provide useful information about the location and geometry of the models, but the images are diffused and unfocused, while the focusing inversion reconstructs very well the original models of the cube and the slab. The fault is practically invisible in the smooth image, while it can be clearly recognized in the sharp image. Red lines show the flight path. A map of airborne magnetic data.
Red lines show the flight paths.
We applied to this data the conventional smooth inversion and the new developed inversion method with focusing and compression. Figures 7-9 show the results of the inversion. The smooth inversion result, a horizontal slice of the inverse magnetic susceptibility distribution at a depth of 800 m. The color scale corresponds to anomalous susceptibility in SI units. The 3-D projection of the focusing inversion result, the inverse magnetic susceptibility distribution at a depth of 1100 m.
