Figure 8From: Tracing of paleo-shear zones by self-potential data inversion: case studies from the KTB, Rittsteig, and Grossensees graphite-bearing fault planes Model 3: data contaminated with 7% noise. Inversion results (top panel). Behavior of the normalized misfit and objective functional of the SD method (middle panel) and the GN method (bottom panel). The observed and predicted data are shown in open and solid circles, respectively.Back to article page
