Antarctic reworking and differentiation of continental crust along the active margin of Gondwana: a zircon Hf-O perspective from West Antarctica / Chris Yakymchuk, and 5 others.

Title: Antarctic reworking and differentiation of continental crust along the active margin of Gondwana: a zircon Hf-O perspective from West Antarctica / Chris Yakymchuk, and 5 others.
Author(s): Yakymchuk, Chris.
Date: 2013.
Publisher: London: Geological Society
In: Antarctica and supercontinent evolution. (2013.),
Abstract: Reports results of Hf-O isotope analyses of zircons from two generations of granite in Fosdick migmatite-granite complex of Ford Ranges of Marie Byrd Land, Antarctica, located along former active margin of Gondwana. Granites are hosted in high-grade equivalents of supracrustal sequence and infracrustal calc-alkaline intrusive suite. Hf-O isotope signature of zircons from Devonian-Carboniferous granites suggest crustal reworking as dominant process, but isotopically more juvenile source is required to explain wider range of εHf values in zircons from Cretaceous granites. Although Hf-O and Nd isotope characteristics of Fosdick complex granites are similar to Permo-Triassic granites from Antarctic Peninsula, they contrast with Hf-O and Nd isotope results from other localities along and across former active margin of Gondwana, suggesting significant margin-parallel and margin-perpendicular variations in both amount and nature of crustal reworking v. crustal growth with time.
