Borehole camera photograph with small-scale structures from the shaly facies (MI niche, unrolled borehole wall of BSO-37 at a depth of 12.15 m, oriented normal to bedding with azimuth 330°, dip −40° downwards, area of 58 mm by 63 mm), showing a highly tectonically deformed zone approximately 6 m behind the Main Fault, consisting of calcite shear-veins and a S- (schistosité) and C (ciscaillement) shear-band. The location of the MI niche and the Main Fault is shown in Figure 6 of Bossart et al. (2017a)
