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.

Dear Michael Tellinger, You are an inspiration to us all! We've briefly talked in some of your previous video's livechats about scheduling you for a podcast interview. sadly the email address you had posted at the time didn't work for some reason. What is the best way to get a hold of you to schedule a future interview good Sir? I promise that you will not be disappointed! i have many parallel research discoveries to share with you, as well as help verify your own discoveries! especially when it comes to megalithic sites and giants! I have found many such sites around where I live here in Alberta Canada

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.

@LymanAlphaBlob 18 дней назад

There was ocean floor during the formation of past supercontinents as well. The ocean floor and even some continental crust gets recycled into the mantle via subduction. Unfortunately we don't know what it looked like, other than an assumption that it looked much like it does today.

@DonnaCsuti-ji2dd 13 дней назад

Remember new ocean floor keeps forming constantly along the mid Atlantic ridge and that pushes Europe and Africa eastward and North America and South America westward ( then subduction probably occurres on both sides of the Pacific ocean ). Basically the land masses are always on the move and occasionally probably come together into gondwana like masses with the continents all together.

@@DonnaCsuti-ji2dd There are mid-Pacific ridges as well producing new ocean floor, pushing Asia West, and North America East. But how can that be? It only makes sense if you realize that the earth is expanding. The so-called "subduction" is assumed, not proven.

@@LymanAlphaBlob All of the ocean floor around the globe is no older than 200 million years. How is it that there is not one spec of ocean floor that can be aged prior to the "breakup of pangea"?

@LymanAlphaBlob 12 дней назад

@@peterdebaets4590 there is plenty of ocean floor around the globe older than 200 million years. You don't even need to look in the water. A large percentage of the fossils/fossil sites we have access to today on dry land are from ancient lithified seafloor that is currently above sea level. Do you believe that there are fossils older than that?
