Biography

Terrence Mernagh obtained a B.Sc. (Hons) and a Ph.D. from the University of Newcastle. He worked at the Bureau of Mineral Resources/AGSO/Geoscience Australia from 1984 to 2014. He is currently a Visiting Fellow at the Research School of Earth Sciences.

His work involves studies of mineral systems and the geochemical modelling of fluids and alteration associated with ore deposits and he has over 30 years’ experience in fluid inclusion, laser Raman and infrared spectroscopic techniques. He is a Fellow of the Geological Society of Australia and has over 100 refereed publications in scientific journals. These publications cover work on a large variety of mineral deposits including copper mineralisation at Mt Isa, gold deposits in the Yilgarn Craton, Pilbara Craton, Lachlan Fold Belt, Tennant Creek, and the Tanami region, unconformity uranium deposits in the Northern Territory, tin-tungsten deposits in the New England Fold Belt and China, VHMS deposits at Hellyer and Mt. Chalmers, porphyry copper-gold deposits in the Philippines, platinum group minerals in layered intrusions in the Pilbara Block, and a number of related mineralogical studies.

Terrence has provided reports to the government on Australia’s potential to supply critical commodities and he also has experience in groundwater analysis and the formation of salt lakes. He has completed a review of Australian salt lakes their potential for strategic resources. He is also currently conducting research on the Great Artesian Basin for The Cooperative Research Centre for Greenhouse Gas Technologies (CO2CRC).
