Figure 20From: Tracing of paleo-shear zones by self-potential data inversion: case studies from the KTB, Rittsteig, and Grossensees graphite-bearing fault planes The KTB site. Sketch showing the geologic setting in the vicinity of the KTB-HB borehole (redrawn From Figure six of Stoll et al.1995; for the legend of the various rock types shown, see that figure). Note that the fault system F2 extends further in depth to about 4 km (see Figure four in Emmermann and Lauterjung1997).Back to article page
