This project will add to existing data of provenance tracers of East and West Antarctica by adding U/Pb of detrital zircons, U-Th/He subsets, and Ar-Ar of detrital hornblende, mica, and feldspars from till from nunataks at major glacier outlets and beneath three West Antarctic ice streams.
OUTCOMES: Four batches of samples have been analyzed. Most work has been in a supporting role.
Character, Timing and Origins of the Late Neoproterozoic Shuram-Wonoka Carbon Isotope Excursion and Associated Paleocanyons in South Australia
Collaborative Research: Deglacial ice dynamics in the Weddell Sea embayment using sediment provenance
Collaborative research: Geochemical variation of the Pacific crust subducting beneath the Izu-Bonin
