- Abstract:
- The Antarctic Peninsula is made up of suspect terranes accreted to the Gondwana margin in the Mesozoic. The peninsula fills a key gap in the margin between South America and New Zealand. The ages of detrital zircons in sedimentary rocks (determined using SHRIMP) give information on the magmatic and tectonic history' of their source regions, and suggest that the peninsula's suspect terranes have exotic sources. However, age patterns alone have proved a poor discriminant, because major magmatic and tectonic events appear to be global or supercontinent-wide. This request for AFI funding is to support an isotope geochemist to apply a new technique, using LA-PIMMS-determined Hf isotope ratios in zircons, to identify isotopically distinct groups within zircons age populations, and thereby to identify Antarctic Peninsula terrane sources, within and without Gondwana.
