NEW: May 2020 - WA Division Online Presentation
Presenter: Vitor Barrote (Monash University and Curtin University)
Topic: 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.

25 October 2019 - Geochemical methods of nickel exploration workshop (Joint GSA WA Division & CSIRO)

Description: This workshop provides advanced hands-on instruction on the use of lithogeochemistry of igneous rocks in mineral exploration, with major focus on magmatic Ni-Cu-PGE deposits. The workshop will present general principles of major and trace element geochemistry, specific application to komatiite and mafic-ultramafic intrusion hosted ore systems, discussions of applications to weathered and altered rocks, and a variety of classification/discrimination methods. The workshop will use ioGAS software and will also touch on the use of Python codes for data analysis.

Details: The Geological Society of Australia (WA Division) facilitated a multidisciplinary and interdisciplinary day-long symposium on the Pilbara Coast and offshore regions, in collaboration with the Wetlands Research Association Inc. and Geoheritage Australasia. The Symposium was  held in association with the AMSA 2019 Marine Science for a Blue Economy Conference (Fremantle) http://amsa19.amsa.asn.au/
The aim of the Symposium was to bring together and collate the up-to-the-present and state-of-the art science of universities, government agencies, researchers, and industry in a symposium to share information and exchange ideas towards the understanding and better management of the Pilbara Coast.  The objective also was to produce a quality refereed publication from original work presented at the Symposium
If you are interested in presenting an oral paper or poster at the Symposium or alternately developing a poster paper, please send a 200-500-word abstract and the paper title to: PCMSS@iinet.net.au by April 30

Themes of the Symposium include: 
(1) coastal geology and nearshore, geomorphology, and physical features of the Pilbara Coast;
(2) coastal, nearshore, and hinterland ecology (including coastal habitats, mangroves, rocky shore, saltmarsh, seagrass, coral reefs, fish, amongst others);
(3) link between geodiversity and biodiversity along the Pilbara Coast;
(4) Indigenous, archaeological, and rock art aspects:
(5) European colonisation and industry;
(6) conservation and management.

7 March 2019 - WA Division Tamala Limestone Fieldtrip - Classic Carbonates & Pleistocene Sea-levels
Details: GSA WA & PESA are offering a short afternoon fieldtrip to the classic Peppermint Grove outcrops along the Swan River, led by Dr. Milo Barham (Curtin University). The Tamala Limestone crops out in a near continuous ribbon for over 1000 km along the southwestern coast of Western Australia. Although dominated by Pleistocene aeolianites, with increasing study and recognition of discrete members, the temporal and environmental complexities of the Tamala Limestone’s deposition are becoming clearer. At Peppermint Grove, several facies are well-exposed in a relatively small area, allowing for easy investigation of classic Western Australian lithofacies, and broader carbonate-dominated sedimentary features from a variety of paralic depositional environments (aeolian to shallow marine). Improved age constraints and investigation of facies-relationships at Peppermint Grove allow for the generation of simple sea-level curves for this section and a broader discussion of Pleistocene glacio-eustatic sea-level curves and their influence on sediment packages.
