36Figure 29. Section along the KR07.In Figure 30 are shown the features HZ20A (green) and HZ21 (violet) (Ahokas &Vaittinen 2007 in prep.) and in Figure 31 the brittle fracture zone OL-BFZ098(turquoise) of geological model (Paulamäki et al. 2006). Surfaces ref10 and ref11match well with the upper layer (HZ20A) and surface ref1 with the lower layer (HZ21)in Figure 30 (Ahokas & Vaittinen 2007). Ref 9 in Figure 31 matches with the OL-BFZ098, and may indicate it could continue towards borehole KR29 (280 – 330 m,met at 330-331 m). Surface ref5 is located near the borehole KR29 and could becombined with the surface ref9 and therefore also be part of the OL-BFZ098.
