MASTER OF ECONOMIC GEOLOGY SHORT COURSE

Ores in Magmatic Arcs – Tasmania and the circum-Pacific


 

Date & Time

22 November – 3 December, 2021


 

This short course will provide participants with an introduction to the ore deposit styles that characterise arc-related geological environments. It will include reviews of the regional and local geology of selected magmatic arcs, along with detailed evaluations of ore deposit characteristics, mineralisation styles and genetic models. Exploration techniques for magmatic-hydrothermal ore deposits are discussed in detail and recent exploration results are evaluated in terms of various genetic models

The first week of the course includes a one-week field excursion to western Tasmania to learn about Cambrian polymetallic VHMS and high sulfidation state mineralisation that formed in a back-arc setting, and DevonianCarboniferous skarn, vein, and granite-related carbonate replacement style Sn-W-Fe-Cu-Zn-Pb-Ag deposits that formed in a post-collisional orogenic belt.

The second week of the course will involve lectures and practical exercises at CODES, reviewing case studies of ores from magmatic arcs from South America (Chile, Peru), Indonesia, the Philippines, Papua New Guinea (Lihir, Porgera, Wafi-Golpu) and eastern Australia (Macquarie Arc), utilising our extensive sample and teaching collections that reside in the CODES archives.

Please note that mine site visits are dependent on COVID protocols at the time of travel and may be cancelled at the last minute. Alternate field and/or laboratory activities will be scheduled in response to covid disruptions.


 

Ores in Magmatic Arcs

is offered as a unit in the national Minerals Geoscience Masters program.


 

COURSE PRESENTERS

David Cooke is Professor of Ore Deposit Geochemistry and Director of CODES. He has extensive research expertise in hydrothermal fluid chemistry and oreforming systems, specialising in porphyry and epithermal deposits.
Michael Baker is a Senior Research Fellow in Economic Geology at CODES. He has extensive research expertise in mineral chemistry and its applications to exploration for porphyry and epithermal deposits, and has worked extensively in South America.
Lejun Zhang is a Senior Research Fellow at CODES specialising in the application of alteration mineral chemistry for enhancing exploration in lithocap and green rock environments, and vectoring using SWIR and whole-rock geochemical data.
Indrani Mukherjee is a Postdoctoral Research Fellow at CODES who specialises in pyrite geochemistry and its implications for ocean and atmospheric evolution, and for the evolution of sediment-hosted base metal deposits.
Sebastien Meffre is the Head of Discipline of Earth Sciences at the University of Tasmania. Sebastien is a specialist in the tectonic evolution of the Southwest Pacific, including the Tasmanides.
Andrew McNeill is the Chief Government Geologist at Mineral Resources Tasmania. He has extensive experience in the geology of, and exploration for, VHMS deposits in the Mount Read Volcanics of western Tasmania.
Adi Maryono is currently VP Exploration and Director at J Resources and Sulawesi Cahaya Mineral. With 32 years of diverse experience in Au-Cu and Ni exploration, he has been involved in discoveries of world-class Cu-Au porphyry and Ni laterite deposits and other smaller Au deposits
Jonathon Hoye is the Senior Geologist Orebody Knowledge at CMOC – Northparkes Mines, responsible for exploration strategy, targeting, research and geometallurgy. He has been an exploration geologist for both junior and major mining companies, exploring for deposits in the magmatic hydrothermal continuum, with a strong focus on alkalic porphyry and epithermal systems in the circum-Pacific region.
 

 

TRAVEL AND CLOTHING

All participants must have appropriate PPE for mine stie visits (steel-capped boots, long-sleeved shirts, long sturdy trousers). CODES will provide hard hats, reflective vests and safety glasses if required. You will need sun cream, lip balm and moisturisers, and cold and wet weather gear.
