Extreme persistence of cratonic lithosphere in the southwest Pacific: Paleoproterozoic Os isotopic signatures in Zealandia

McCoy-West, Alexander; Bennett, Victoria; Puchtel, Igor S; Walker, Richard J

Description

Zealandia is a largely submerged, continental fragment in the southwest Pacific, generally considered to be derived from East Gondwana, but whose origins, age, structure, and relationships with other continental masses are poorly known. To explore the development of this microcontinent, a suite of mantle xenoliths was assembled from 12 localities throughout New Zealand, an emergent part of Zealandia. The 187Re-188Os isotopic systematics of the xenoliths yield model ages (TRD2) between 0 and 2.3...[Show more]
