Cenozoic tectonic evolution of the New Zealand plate-boundary zone: A paleomagnetic perspective

New Zealand straddles the obliquely convergent boundary between the Pacific and Australian plates, with subduction of Pacific plate along the Hikurangi margin. Finite plate reconstructions predict ~ 800 km of relative plate motion since ~ 43 Ma, with 80–90° clockwise rotation of the Hikurangi margin...

Description
Summary:New Zealand straddles the obliquely convergent boundary between the Pacific and Australian plates, with subduction of Pacific plate along the Hikurangi margin. Finite plate reconstructions predict ~ 800 km of relative plate motion since ~ 43 Ma, with 80–90° clockwise rotation of the Hikurangi margin since ~ 20 Ma, at an average rate of 4–4.5°/Myr, and the short-term deformation (
