The central South Island has long been a favourite site to study and model oblique continental collision, because the orogen is young, narrow, and a single structure, the Alpine Fault, takes up more than 70 per cent of relative plate motion.
The orogen is highly asymmetric and varies along strike as the nature of the two colliding plates change along the boundary.
I will explore the 3D structure and kinematics of the orogen, and discuss how regional deep-seated tectonic processes of mountain building are geodynamically interconnected with climate, landscape, and near-surface geological processes that create local fluid flow, effective stress, and temperature anomalies.
