Fig. 23From: 3-D inversion of magnetic data based on the L1–L2 norm regularizationThe slice of the optimal magnetic model. The slice of the optimal magnetic model at the depth of a 200 m, b 400 m, c 600 m, and d 800 m, respectively. On each figure, the location of the exposed serpentine belts is displayed in solid lines. The coordinate system of this figure is UTM, and the color scale indicates the induced magnetization in A/mBack to article page
