This channel provides recordings of events (predominantly monthly talks) held by the Western Australian Division of the Geological Society of Australia. This channel is currently freely available to all as a geological resource for society but may become restricted as a members only section in the future.
The Geological Society of Australia was established as a non-profit organisation in 1952 to promote, advance and support Earth Sciences in Australia.
The Society has a Division in each state and territory, each of which hold regular meetings to enable members keep in touch with scientific developments, present the results of their work and contribute to discussions on vocational and scientific topics. Specialist Groups cater to different sectors of the Earth sciences. For more information about joining the Geological Society of Australia visit the link below.

Stephen Poropat: Paleobiogeographic implications of Cretaceous Australia's fossil record
Presentation: Palaeobiogeographic implications of Australia’s Cretaceous fossil vertebrate record.
The Australian Cretaceous vertebrate fossil record is patchy, biased towards the eastern half of the continent, and temporally restricted. I explore why these biases exist and how they can be overcome. I explore what Cretaceous vertebrate fossils we do have and what they tell us. But I also explore what we might be missing - and might be able to reasonably expect from Australia’s Cretaceous fossil record in the future.
Speaker bio:
Stephen Poropat’s deep-seated passion for palaeontology all started with a book, a Christopher Reeve-narrated documentary about dinosaurs, and the trials and tribulations of Littlefoot in The Land Before Time. Since undertaking a PhD at Monash University on microfossil invertebrate biostratigraphy, Stephen has worked as a postdoctoral researcher - focused on dinosaur anatomy, phylogenetics, and biogeography - at Uppsala University in Sweden and Swinburne University of Technology in Melbourne. He is now Deputy Director of the Western Australian Organic and Isotope Geochemistry Centre at Curtin University, where he is working as part of Prof. Kliti Grice’s team in an attempt to understand the pathways that lead to exceptional fossil preservation. He has a long-standing association with the Australian Age of Dinosaurs Museum in Winton, Queensland, and he is passionate about popularising Australian palaeontology to the general public.
Presented at Public House Perth on the 4th of September 2024 for the Geological Society of Australia - Western Australia chapters' monthly technical talk.

Finley Rea: Accessory mineral indicators of metallogenic fertility applied to IRGS
มุมมอง 3936 หลายเดือนก่อน
Microchemical analysis of accessory minerals, such as apatite and zircon, provide insight into geological processes operating during (and posdating) magma crystallisation, some of which may be indicative to metallogenic fertility. The ~3.5 Moz Mount Leyshon Au-(Bi-Ag) deposit, a breccia-hosted intrusion-related gold system (IRGS) in northeast Queensland, provides an excellent opportunity to dev...

Chris Fisher: A multi-mineral approach to understanding crustal evolution: examples from the Archean
มุมมอง 1242 ปีที่แล้ว
Chris describes the so-called Hf-Nd paradox. He gives evidence to show that this paradox is commonly only a feature of poly-metamorphic terranes and can be explained by Sm-Nd mobility rather than being a fundamental feature of the early Earth. U-Pb and Sm-Nd analyses of apatite and titanite can help to clarify the record of crustal growth and evolution.

Parabéns!
Great talk. Thanks
WOW thank you very much I live in Bridgetown WA and TO MY NORTH , WEST, EAST, AND SOUTH I HAVE FOUND A FEW GRAMS HERE AND THERE. GREAT FINDS AFTER WASH OUTS. I HAVE A PIECE OF QUARTS ITS VERY CLOUDY QUARTS WITH DARK GREY MINERALS RUNNING THROUGH THE QUARTZ. YOU CAN SEE CLEARLY THIN RUNS OF GOLD IN THOSE DARK SECTIONS THE WHOLE THING WEIGHS 45 kg lol I’m guessing but at least 2 ounces would be in there. But it’s a nice specimen.. PLEASE FORGIVE ME MY GEOLOGY LINGO IS FAR FROM SATISFACTORY.😊 THANK YOU FOR HELPING TO UNDERSTAND MY REGION.ITS CRAZY THE AMOUNT OF MINERALISATION.🇦🇺👍❤️
I have been pleasantly surprised when crushing up a small specimen with how much gold there was. Mine had ironstone and quartz so couldn’t do a specific gravity test but recommended you do it if you can as you may be surprised by how much there is. Cheers
Good !
Amazing part of the world glad I got to spend 5 years there in Paraburdoo
I am civil engineer but i did very wide scientific researches about this zone It formed in hydrothermal volcanic mountains In base of the mountains By hydrothermal soulutions in high pressure and heat soultion the gold concentrated by carbon which be activated and absorbs gold also other metal in it and around it Such as active carbon in cyanide sulation More rich layers of graphite more rich of gold The iron sulfur ,zinc ,lead are found there in layers Mountain is very hiegh and black when you dig in it you smell sulfur
Thanks for delivering an interesting and polished talk!😊
Thanks!! Excellent talk
Great talk! Thanks for sharing this on TH-cam. This was very interesting and relevant to my work. I would like to find your paper and think about doing some similar work.
Highly informative, helpful and educative indeed!
Merci!
👏👏👏👏👍👍
Interesting
I love geology .... and dare I say it 'the down to earthedness' of geologists .... well done!
Great!
In optima forma!
Brilliant! So comprehensive and all-inclusive approach. Thank you!
Very interesting! Competently.
