Fig. 24

GPF-Ardèche project: well BA1, modified from Figure 6 of Martin and Bergerat [5]. Core positions of Anelastic Strain measurements (ASR): K6–K50, yielding present stress results (Deflandre and Sarda [35]), to be confronted with palaeo stress directions derived from visual core description of same cores (from Martin and Bergerat [5]), and with FMS borehole wall images.
