a Map of Nusfjord anorthosite showing locations of shear zones and large dykes. Red shading indicates the extent of the high strain zone containing frequent cross-cutting shear zones. Basemap © OpenStreetMap contributors (openstreetmap.org.uk/copyright). b Block diagram showing three-dimensional structure of interlocking shear zones in various orientations. c Cross section taken from line X–X′ shown on map in 1a. The thickness of shear zones in the map is not representative of the actual thickness in field.
