of cracks in the photo

within the Kalak Nappe Complex exposed at Markopp, Repparfjord, Finnmark. Photo: G. Viola

14. Figure 7: A set of composite shear fractures cutting a pegmatite (white area) within a granitic host rock.
The displacement of the pegmatite vein allows geologists to understand what has happened here, a long
time ago. The photo is captured on the island Kalla close to Olkiluoto, SW Finland, where Finnish
authorities are building a deep repository for long-term storage of high-grade nuclear waste. The
structural analysis of who brittle deformation effects the area is important for designing the repository and
for assessing the potential of future seismic activity. Photo: G. Viola.
