Talk title: A new link between the Earth’s deadliest mass-extinction event and largest nickel ore deposits
Speaker: Dr Margaux Le Vaillant, CSIRO Mineral Resources, 26 Dick Perry Avenue, Kensington, WA 6151, Australia
Abstract: The Noril’sk deposits in Russia, most valuable source of nickel on Earth, formed along with giant eruptions of lava 250 million year ago. Mass release of nickel into the atmosphere during ore formation was proposed as a trigger for the Permo-Triassic mass extinction event - termed the Great Dying – killing over 95% of species on Earth. Release of nickel would have promoted a marine organism’s activity with catastrophic greenhouse climatic effects. But how did the nickel get into the volcanic gases? We found the smoking gun: nickel-rich sulphide droplets physically attached to former gas bubbles, frozen into the Noril’sk ores.
About the speaker: Originally from France, Margaux completed her undergrad in Paris (prepa BCPST at St Louis) and Nancy (National engineer school of Geology, ENSG). She then completed her Masters in collaboration with Lulea University of Technology in northern Sweden. In 2011, she moved to Perth to start her PhD at UWA, within the Centre for Exploration Targeting. During her time with CET, Margaux worked on hydrothermal footprints around magmatic nickel sulphide deposits, and will present the results of this study today. Over the last three years, Margaux has been working at CSIRO as a post-doctoral fellow, looking at the physical processes related to the emplacement of magmatic nickel sulphide deposits, she now joined as a research scientist leading the Hydrothermal footprint team.

The GSA-WA Division 2016 Annual General Meeting was held at the Irish Club, Subiaco on Wednesday 4 May 2016.
Gibb Maitland Medal 2017
Call for Nominations - Now Closed
The Gibb Maitland Medal was established by the Western Australia Division of the Geological Society of Australia in order to recognize individuals who have made substantial contributions to geoscience in Western Australia. It is named for Andrew Gibb Maitland, Government Geologist from 1896 to 1926, who established the Geological Survey of Western Australia. The Medal is usually awarded annually and nominations are now sought for the 2017 Award.
In assessing nominations, the primary consideration will be the significance of individuals’ contributions to geoscience and the quality of their scientific work. To reflect the importance of resources to Western Australia, particular consideration is given to contributions that relate in some way to discovery or documentation of mineral and petroleum resources in the state. Geoscientists from industry and from academic, government or other institutions are all eligible for the award, but especially those who are actively engaged in their careers, whether in Western Australia or not. Unsuccessful nominees do not have to be renominated because their names automatically remain on the list for annual consideration for five years, although sponsors may wish to update the nomination.
Recent recipients of the Medal include:
2005 Dr Jon Hronsky WMC Resources
2007 Dr Peter Eadington CSIRO
2009 Mr Philip Commander Department of Water
2010 Dr Tim Griffin GSWA
2011 Dr Stephen Barnes CSIRO
2012 Dr Scott Halley Mineral Mapping Pty.
2013 Professor Cam McCuaig Centre for Exploration Targeting, UWA
2014 Dr Ravi Anand CSIRO
2015 Dr Graham Begg Minerals Targeting International Pty Ltd
2016 Professor Kliti Grice Curtin University
2017 Dr Ian Tyler GSWA
No awards were made in 2006 or 2008
Nominations should be in writing, with sufficient details of the nominee to allow evaluation by the Awards Subcommittee.
