Antarctica
Project Type: Research

DESCRIPTION: 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.

SPONSOR: National Science Foundation (NSF)
