Geochemistry of ore metals at very high temperatures. The world’s largest copper and gold mines occur in extinct volcanoes around the Pacific Rim. Understanding how these essential metals are mobilised from magmas in the roots of volcanoes to become ore deposits and how to recognize where this has occurred is crucial in exploration for new deposits.
Geological applications of synchrotron radiation: magmas, fluids, ores and minerals. This project will use the Australian synchrotron facility to study magmas and minerals to improve our understanding of the formation of ore-deposits and the evolution of the continents.
Magnetite and metal-rich sulphides in arc magmas. Ascending magmas cool and crystallise a variety of minerals. Triggering sulfide deposition which hosts base and precious metals is a critical point in magma evolution. This research will explore the role of magnetite as this trigger and its potential as a tracer of this process.
