Gondwana’s Child – the geological making of Tasmania

The Royal Society of Tasmania: 7th April 2024 lecture
Dr Keith Corbett OAM
Dive into the geological wonders of Tasmania with Dr Keith Corbett.
In this “Child of Gondwana” lecture Keith describes the geological makeup of Tasmania, explaining how the unique geology of the island state came to be created. Tasmania has a wonderful diversity of rocks and is a veritable textbook of geological time and Keith’s lecture assists our understanding and appreciation of our deep history.

Keith Corbett, educated at the University of Tasmania, has spent most of his working life in the mountains of Tasmania. In a distinguished career of over 60 years as a field geologist Keith was awarded the WH Twelvetrees Medal for contributions to Tasmanian geology in 2010, and a Medal of the Order of Australia in 2023.

Thanks so much for hosting Dr Corbett and sharing his lecture with us.

If you haven't heard of Nick Zentner at central Washington University he's a geology Professor who has a free on line teaching program that he started doing more actively when covid shut things down he started doing in his back yard cause he was bored.He got a huge following and stimulated us already interested in the subject to learn more. He didn't quit and neither did we so you may notice plenty of us listening to you and other geologists also. So you might like also looking up Nick. Really nice man also and great teacher ( he takes us along on hikes and field trips by carrying his phone).
Thanks for sharing your very interesting talk.
Just a side note ( a close friend's mom was Australian.. I'm old so she has passed... and my parents liked to take British tours and became good friends with a couple from the tours who were Australian and they came to USA and stayed with us and we toured them around... so I'm quite fond of Australia ). Please do share future talks on utube also.

Looking forward to reading your work, thank you.

What do you think about the Karin Sigloch-Mitch Mihalynek conclusion that tectonism is propelled by "90% slab-pull (subduction) and 10% ridge-push (spreading ridge)"? This limits all tectonic observations to the crust and ignores the role of the mantle.

My observation of the tectonic principle is a conveyor belt or tank track (slab) + back drive-wheel (mantle convective upwelling) + conveyance/motion ( slab on mantle convection flow) + front idle-wheel (mantle cooling descent.)

I understand their conclusions, but only to the point of accommodating the rigid crust for conveyance via mantle convection.

How wonderful to hear you speak about the origins of this beautiful island!

We are still slaves to the govt.

Fun rocks, terrible politics. No state should endorse a conlang. Keep the real names of the places please.

Why is it that if you bury the ocean floor by reverse age you get all the continents fitting together into a ball on a smaller globe? That seems like an astounding coincidence.
