New Zealand Journal of Marine and Freshwater Research abstractsTHE ANTIPODES FRACTURE ZONE, A MAJOR STRUCTURE OF THE SOUTH-WEST PACIFICDavid J. CullenNew Zealand Oceanographic Institute, Department of Scientific and Industrial Research, WellingtonAbstract The steep Antipodes Scarp, along the eastern boundary of the Campbell Plateau south-east of New Zealand, is attributed to dextral tear-faulting within a NE-SW belt, the Antipodes Fracture Zone, which also truncates the eastern end of the Chatham Rise. A complementary zone of sinistral movement, the Waipounamu Fracture, separates the Campbell Plateau and Chatham Rise from mainland New Zealand. The origin of these fracture zones is linked with that of the parallel Alpine Fault of South Island, and is related to a phase of NE-SW crustal compression that dominated the New Zealand region during the Mesozoic era. It is suggested that this compression resulted from the north-eastward "drift" of the Australian craton and the simultaneous elevation of the Darwin Rise in the central Pacific.
