The steep structures were (sub)vertically flattened during formation of the flat-lying structures, indicating that the higher grade rocks formed as part of a shear-zone system. A similar conclusion can be drawn from the relation between deformation and metamorphism in the higher grade rocks. We suggest that the shear zone may have accommodated crustal extension.
