Connections Between Volcanoes and Ore Deposits
November 22, 2015
Time: 2.00 pm
Meeting Room, QVMAG
The Royal Society of Tasmania 2015 Launceston Lecture Series.
Presented by Professor Jocelyn McPhie, Adjunct Professor, University of Tasmania and Principal Consultant, McPhie Volcanology.
Active volcanoes are locations where the Earth’s internal heat energy is focussed and channelled to the surface. This heat energy drives the circulation of subsurface water, gradually leaching metals from the enclosing rocks and creating metal-rich “hydrothermal fluids” that may form ore deposits. Some volcanoes erupt magmas that are especially metal-rich and directly generate ore deposits without the involvement of any hydrothermal fluid. Yet other kinds of volcanoes are simply carriers of valuable commodities to the Earth’s surface. Active volcanoes eventually become extinct but the ore deposits connected with them remain. Finding these ore deposits depends on understanding the volcanoes they were associated with.
Prof. Jocelyn McPhie is a volcanologist with more than 30 years’ experience, mainly in academic positions in Australia, Germany and the USA. Her research contributes to the understanding of how volcanoes work, especially volcanoes on the seafloor, and the connections between volcanoes and ore deposits. She currently operates as a consultant to the mining industry while retaining an Adjunct Professor position at the University of Tasmania.
