Thermochronologic constraints on the breakup of the Pacific Gondwana margin: The Paparoa metamorphic core complex, South Island, New Zealand

Spell, Terry; Tulloch, Andrew; McDougall, Ian


Continental extension preceding the breakup of Gondwana in the Cretaceous produced a metamorphic core complex preserved in the Paparoa Range on South Island, New Zealand. Most features of classic Cordilleran core complexes are present including high metamorphic grade lower plate rocks separated from low-grade upper plate rocks by detachment faults, syntectonic granitic intrusions and volcanism, and thick sequences of subaerial breccias and conglomerates. Dating of lower plate rocks by the...[Show more]
