Multiple Sulfur Isotopes workshop

Feb 02, 2019

A free workshop entitled “The latest advances in the application of multiple sulfur isotopes in the understanding of hydrothermal and magmatic systems” was hosted by the Centre for Exploration Targeting’s Crystal LaFlamme and Marco Fiorentini on November 28th. This free workshop for CET’s industry members brought together scientists from Australia, Japan, France and Canada to integrate knowledge in the systematics of multiple sulfur isotopes and the relationship to the understanding of the genesis of ore deposits and their isotopic footprint. The workshop focussed on multiple scales from the district to ore shoot scale. Systems investigated included: orogenic and intrusion related gold with examples including Tropicana, Agnew, Callie, and the Golden Mile, Abitibi, komatiite systems including the Black Swan, modern seafloor and ancient VMS systems including the Okinawa Tough, the Nimbus and Degrussa deposits, and Ni-PGE systems in the Alps and at Noril’sk. 

This day-long workshop was funded by the University of Western Australia’s Research Impact Grant awarded to LaFlamme and Fiorentini. Its purpose was to support communication of the research in multiple sulfur isotope space to industry partners. We also sought feedback from industry attendees in the application of these newly developed methods. From this feedback we will seek to improve the workflow in the application of multiple sulfur isotopes within exploration programs. 

Further an effort was made to demonstrate the latest developments in techniques developed to measure and monitor these differences. These complimentary analytical techniques are available in a variety of laboratories around the world, and from this workshop we are seeking to collaborate in developing a workflow in the rapid and accurate collection of multiple sulfur isotopes. Following the workshop, four of the presenting scientists (from Canada, France, and Australia) traveled to Kalgoorlie in order to further discuss how multiple sulfur isotopes can be applied to orogenic gold deposits in a practical context.
