GSA WA special - Dr Vitor Barrote "4D EVOLUTION OF REPLACEMENT-TYPE VHMS ORE SYSTEMS, YILGARN, WA"

Dr Vitor Barrote (recent PhD graduate of Curtin University, now Monash postdoc) took some time out to record a fantastic presentation on aspects of his PhD work on Yilgarn Craton mineralisation entitled "4D EVOLUTION OF REPLACEMENT-TYPE VHMS ORE SYSTEMS IN THE YILGARN CRATON, WESTERN AUSTRALIA" ABSTRACT The discovery of mineral deposits is critical to the long term sustainability of the Australian mining industry. Innovative approaches to mineral exploration and the application of state-of-the-art research techniques to improve the comprehension and detection of ore bodies is fundamental to address the formidable challenges posed by Australia’s complex geological framework and paucity of outcrops. 4D evolutionary models of ore deposits can be generated by combining geological observations with data from several isotopic systems, in a multi-disciplinary approach, to constrain the timing of major geological processes present in the development of a deposit. These models contribute to a better understanding of the evolutionary framework of an ore deposit, the timing of mineralisation, and the processes that drive metal supply and precipitation. This is particular true in Archean replacement-type VHMS deposits, where the syn-volcanic timing of the mineralisation is not always clear. Ultimately the construction of a 4D framework culminates in the development of new or improved exploration tools. BIO Vitor Barrote is a Research Fellow at the Isotopia Facility, Monash University. His research interests lie in the field of isotopic geochemistry and geochronology, with a special interest in technical development and the use of multidisciplinary studies applied in unorthodox ways in order to solve unusual problems. He has been involved in Economic Geology for the good part of his academic journey, from his master degree at UFMG (Brazil) to his recent PhD at the John de Laeter Centre, Curtin University, where he studied VHMS deposits from Western Australia.
