My research involves the study of volcanoes and their products, granites and related rocks, the tectonic history and magmatic systems of the south-west margin of the Pacific plate, and subduction related intrusive rocks. My particular interest is in the application of trace element, major element, and isotope geochemistry to rocks derived from magmas. Current research is concerned with a range of topics including modern volcanic rocks of New Zealand and the Kermadec volcanic arc, Tertiary aged intraplate basaltic volcanic rocks in south-eastern Australia and Antarctica, high grade metamorphic rocks and granites of the Windmill Islands in east Antarctica, Palaeozoic granites and related rocks in south-eastern Australia, and the tectonics and igneous rocks of the Vanuatu subduction system.
Three projects of particular interest at this time are:
- The geochemistry, and petrogenesis of andesites of Ruapehu and Taranaki Volcanoes in North Island New Zealand: This is a collaborative effort with colleagues from University College Cork and Massey and Auckland Universities. The research is being supported by the Marsden Fund and through a Public Good Science and Technology Fund subcontract and has in the past attracted significant funding from the Australian Research Council. The objectives of the study are to understand the processes and time scales of magmatic and volcanic processes taking place within the Quaternary andesitic volcanoes of North Island New Zealand.
- Permo-Triassic sub-volcanic intrusive systems in Southland, New Zealand. This is a joint project with colleagues from the University of Otago and the Australian National University. Intrusive complexes exposed along the Southland coast at Bluff and at the southern end of the Longwoods Range, represent crustal level magmatic systems underlying Permo-Triassic, subduction-related volcanic arcs that were probably similar to the present day New Zealand arc. The project seeks to use these unique exposures to gain insights into the magmatic processes operating within an arc volcanic system.
- Volcanology and petrology of eruptive centres on the flanks of Mt Morning volcano, Erebus magmatic province Antarctica. This is a joint project, funded by the New Zealand Antarctic Institute, with a colleague at the University of Otago. The project commenced in 2004 and the objectives are to understand the magmatic history of this complex volcano, the nature of the volcanic processes by which flank volcanoes were constructed, and the relationship between volcani flux and sedimentation history in nearby basins.
