A Forearc Stratigraphic Response to Cretaceous Plateau Collision and Slab Detachment, South Island, New Zealand

Abstract

The subduction of oceanic lithosphere at convergent plate margins is frequently disrupted by second-order processes, such as collision of plateaus, aseismic and spreading ridges ("ridges" hereafter), and seamounts. These disruptions can result in a range of sedimentological, magmatic, deformational and tectonic responses, and potentially lead to changes of subduction polarity or the termination of subduction (Austermann et al.
