23. Models, Drobbles, and Data in Magmatic Sulfide Deposits

Discovery to Recovery

Magmatic sulfide deposits have arguably the most quantified deposit model, but what are the game changers in our understanding? Despite a decades old foundational model for their formation, what is new and what should be considered in the search for new resources? This episode checks in with an expert in magmatic sulfides engaged in the global pursuit as well as those researching emerging ideas that shed new light on the model, including some which have implications for exploration.
Peter Lightfoot, Lightfoot Geoscience and adjunct professor Western University, began his career in academia and at a survey, but then seized the opportunity to make the switch to exploration and has never looked back. He gives us his five game changers in the understanding of the ore deposit model for magmatic sulfides, from mineral systems to big data and structural analysis.
The recognition of ‘drobbles’ – the coalescence of vapor and sulfides in the formation of magmatic sulfide ores stems from how we ask questions, the scale of observation and fundamental experimental work. Margaux Le Vallaint, CSIRO, Kensington, W.A., Australia, talks about her research into the role of gases in the formation of Norilsk massive Ni deposit, with implications for the Permian-Triassic extinction event.
In the lead up to the early career Pt Symposium, in May 2022 (check it out on the MagSul website), keynote speaker, Eduardo Mansur, Norges Geologiske Undersøkelse, talks about developments in mineral analysis and potential applications for exploration. Plus, what does an early career scientist think the future holds for the science of magmatic sulfide deposits?
