Geochronology, Thermochronology, Geochemistry
I am a final-year PhD student working on a Marsden-funded project "Using the world's most rapidly slipping normal fault to understand the mechanics of low-angle normal faults and the dynamics of continental extension" with Tim Little as PI. My part in this project is to determine the evolution and exhumation history of the Suckling-Dayman massif in an absolute-temporal sense by applying a combination of geochronologic (U/Pb) and thermochronometric (fission-track and (U-Th-[Sm])/He) methodologies.
After completion of my thesis I will process (and hopefully date!) samples from various sedimentary units (Uga Sandstone, Ruaba Sandstone, Awaitapu Claystone) exposed on the Cape Vogel Peninsula.
I would hope to date (volcano-)sedimentary units for which there are currently no/little/poor chronological constraints including the Amora Conglomerate in the upper Musa Valley area, the Iauga Volcanics in the Cape Ward Hunt area, the Eia Beds in the Morobe area and others. Having found zircon in intercalated sediments in the Goropu Metabasalt I am hopeful that such sedimentary pockets may exist in the Emo Metamorphics. Other than that, trying to constrain the age of the PUB (e.g. by Lu-Hf, Sm-Nd, or possibly Re-Os dating) would be something I am interested in.
