White Island is a subduction-related volcano in New Zealand that passively discharges approximately 100 tonnes of copper and 4.5 kg of gold to the atmosphere each year. (Photo copyright Richard Arculus, Australian National University)

The Magmas and Ore-forming Systems (MOSt) research group explores links between magmatic processes within the other, such as those that drive volcanic eruptions and form planetary crusts, and ore-formation, including hydrothermal porphyry copper deposits that provide almost three-quarters of the world’s copper. Thus MOSt lies at the interface of igneous petrology and economic geology, approaching its research goals through a combination of geological observations, high temperature and pressure experiments, microbeam analysis, geophysics, and numerical models.
