Exploring the plate boundary structure of the North Island, New Zealand



New Zealand's North Island and the offshore region to the east are one of the few places on Earth where many features of an active convergent margin can be studied along a compact transect. All components normally identified with continent-wide deformation are present. From east to west, these include oceanic plateau, trench, accretionary prism, axial range, active andesite volcanoes, back-arc rift, fold and thrust belt, and foreland basin. The North Island, therefore, represents one of the best modern, active continental margins for assessing the role of subduction on compressional and extensional deformation of continental crust.
