Short summary
We find pinch and swell structures from a mid-crustal zone in Fiordland, NZ are initiated by brittle failure of the strongest layer. Modelling this strain localisation and viscous flow shows material softening is important and structures develop in both Newtonian and non-Newtonian flow, with strain localisation impacting both bedding rotation and structure formation. We also find strain localising behaviour combined with viscous flow is a viable alternative representation of the middle crust.
