The state of Victoria, in the South Eastern most region of continental Australia, was home to a massive number of ultra-plinian volcanoes and supervolcanoes during the Devonian era. The state is divided in two, with the largest volcanic activity occurring during the early devonian at a site in Victoria where there was a rifting that was taking place. This rifting allowed magma from deep within the earth to rise up, and in doing so, this extremely hot basaltic magma melted the extremely volcanic bedrock basement of Victoria, turning the chemistry of the magma from a low silica mafic one, to an extremely viscous high silica blend, which led to the formation of over 2 dozen massive volcanic calderas in this region. We will cover this in part 2. In this episode, we are covering the volcanic activity that occurred in the Late Devonian, which was related to a nearby orogeny that was induced by a tectonic collision and subduction that was happening near to here, as more and more of Victoria was continuing to be risen from the deep sea, creating a land more recognizable to that one that exists today, with it being built one step at a time, bit by bit like a puzzle.
These late Devonian eruptions created some of the largest calderas and most powerful eruptions ever seen in Victoria. The most well known and well studied of these eruptions, is the VEI 8 supereruption that occurred in the Cerberean Caldera. This massive eruption is thought to be responsible for, or at the very least, related to the Devonian extinction that occurred due to just how powerful it was, and how immense the climactic effects would've been, especially with the Volcanic winter that without a doubt would've followed this eruption. Along with this, was the creation of some of the most well known features in Victoria in present day, such as Mount Dandenong, also known as Dandenong Ranges, and Mount Macedon. Both of these were extremely large and violent caldera forming volcanic eruptions. The land surrounding these impressive structures have slowly wittled down and eroded around the more erosion resistant volcanic rocks of these calderas, leaving them looking like mountains today, rather then the deep depressions within the earth that they once would've existed as. Along with these, we will also cover the Acheron caldera, and two others that exist north of the Cerberean one, that could've been just as powerful, if not more then what occurred at the Cerberean caldera.

Hey guys! We decided to combine the 3 episodes that we made last year which cover Victoria's Devonian super eruptions. I was originally going to rerecord the audio, because I had a horrible mic back then. But I couldn't find the scripts for these, so we tried to fix it as best as we could. A lot of effort went into the creation of each episode, and they contain a vast amount of valuable information, so I figured it was best to combine them all into a single episode. Hope you all enjoy!
Hi mate. I can put you in touch with an Aussie Phd who works in gravimetrics, seismology etc. He is on CZcams discussions alot. Also would like you to look at an anomaly in Queensland.
Your Chanel is leading the rest .. the hard work that goes into these vids and then the finished product of what we see is always so well explained .. amazing ..
Thanks mate, sensational as always. I’ve learnt so much along the way.
I find it interesting that features out there that I’ve seen thinking I wonder how it was created and having my own theories about it.
I’ve been surprised on how close I was with most of it. thanks again buddy.
❤ from Western Australiastan 🦘
@OzGeographics Job well done it explains a lot. I'm wondering if you have heard of Pine Mountain it's approximately 7 klm east of Walwa on the Upper Murray River. It's supposedly Bigger than Uluru (Ayres Rock) as a single Monolithic rock but has not got the recognition for that. Since the 2019/2020 fires you can see a lot more of it but as you can understand being a geology expert there are a lot more Mountains around this region. Thank you.
I thought I'd heard it before but enjoyed it both times ❤❤❤
How fascinating. I lived in Victoria for a number years and was always intrigued by the various and numerous differences in it's geography. Rain Forest to desert, as well as Plains to the Dandenong Ranges. I would often spend many a week end driving all over. The Grampian are fascinating and a contrast to the Highlands. More please.
I absolutely love this channel, I've lived all over Victoria in my 43 years on this planet and it rocks to learn so much about the places that are so dear to my heart and imprinted in my memories. Thank you so much for all of the brilliant work you do, i really hope someone can back up your claims and get this stuff taught in schools all over Australia. My partner and i were just talking about how much more exciting school would have been here in Victoria if we had this stuff on the syllabus! Is there a way to offer your work to Vic schools?? 🤔
As a kid i was lucky enough to dig up some smoky quartz in my mates uncles back paddock, now I know why it was there! Thanks again for all you do. 👍🏼👍🏼👍🏼👍🏼👍🏼
I like the way this guy encourages us to encourage him 😅 like he needs any encouragement 😜 his enthusiasm is infectious 😁 good stuff 👍🙏
I've spent a lot of time 4x4ing, camping and exploring around Mansfield and Mt Buller. So cool to hear that a lot of those wild ridges I tackled were probably volcanic formations
Absolutely love learning this information. There is a lot of ground movement in the strezlecki range and also a number of seismic faults causing quakes
It would be fantastic if you film your treks to discover Australia’s Volcanic activities. It would be like a show and tell.
Wow, that was Amazing, Thanks!
THANK YOU so much for this (and ALL) of your published video(s). This information is exceedingly fascinating. Additional videos on this topic is hoped for (and very much appreciated).
Enjoying this channel. I lived in Geelong for several years before having to go back to the Americas and I only JUST joined up with a mineral club a little while before I left so I barely had any time to get into it. We visited a few sites for specimens (couple sites for fossil sea life including a sheep paddock with steep hills and so many rabbit bones you almost couldn't step without crushing some, and a site with lava bombs full of tiny peridot crystals) and sightseeing (organ pipes park, etc) which was pretty cool and got me wondering about other random things in the area but never had a chance to investigate like the random scoria just west of Geelong near Colac, or the You Yangs farther north. Also went west to the Grampians. I miss it sometimes, it was really beautiful.
Fantastic, i was born in Benalla and travelled and worked in a lot of areas in the first part of video. Keep up the great work.
I went through Koroit to Warrnambool last year and could tell there was a quite a bit of volcanic lava flow in the area. South Australias rocks seem to be millions of years old and sedate in comparison
Thank you for covering this specific area! I grew up an hour east of Mount Gambier and have always been fascinated with the various volcano's dotting the entire South West of the state and across into S.A
I have been out to the Moorella Dig a few times too, I've got a nice collection of quartz that I've since polished up.
Glad you enjoyed it! Thanks so much for watching. I'm hoping to do a dig in Mooralla myself one day soon :)
Thanks bro I was just learning about Skull Rock and this helps clear up some info on what was going on then. Excellent work as always!
Glad it was helpful! Thanks for watching!
Thank you for researching Australia.
Thanks
Thank you so much for the generous donation mate ☺️ much appreciated!
Will you discuss the lava flow around metropolitan Melbourne and how it influenced the topography at some point? :)
The information you presented is utterly astounding and nearly incomprehensible! So much raw power!!!
You do an amazing job with these videos mate. I know because I'm a geologist, and I have struggled immensly finding decent information on volcanics during this time. It was also Mt Macedon that started my journey of discovery. Thank and and keep up the good work sir!
Thank you so much ☺️ I’m so glad you enjoyed it!
Very amazing violent and very diverse volcanics history, Australia ! I live in Western Arizona and was also amazed to see that in one of the early earth super continents that Australia had a side of its continent butted up against the Western edge of Arizona's ancient border , long before California had slid into Arizona on an ancient oceanic plate . Now Australia is clear around nearly the opposite side of the planet !
Many years ago while living in Victoria Au. we used to picnic in a crater the crater was entered on the left and inner area has a BBQ area & walking trails.
Love it!
my house was in this video. i love this channel.
Another reason to settle in your beautiful country. Wild life, super-vulcanoes.
That' would be cool if you did a video on each place. So interesting.
To answer your question I would love to see on site stuff. You are inspiring me to start my own channel and on site episodes would be next level!
We're about to travel to Western Victoria for holidays, with the natural route passing through Palmer, South Australia. I had to make a solemn promise in advance, at water-pistol-point, to not - repeat NOT - tell the story of the Delameranian Orogeny at the end of the Cambrian and into the early Ordovician (going from about 515 to 500mya), which produced the granites there and along the coast around the Eastern Adelaide Hills, Fleurieu Peninsula, Kangaroo Island, and Victor Harbour, as deep magma intrusions under the mountain range.
So this has compelled me to look for it in a podcast to play, sstarting at about Tungkillo. Highly desirable criterion is that it kicks off with the words, "Julie, listen up".
I watch a CZcams channel called Demolition Dave who is a blaster that breaks up a lot of rock in Australia. Many are boulders that builders encounter when excavating for homes or utilities. I started to wonder about the origin of the rocks involved. Some look like they could be large blobs of magma that were ejected because they are rounded and embedded in dirt high in hills. It seems that if they were rounded by erosion they would be laying on bedrock.
Thanks!
Thanks Steve! I’m glad you got something out of this :)
yes, I would love to see more! I love this stuff!
Loving these videos. Do you know if WA has any interesting areas?
Thank you for your videos I love them
So that's what the Dandenongs are, hmm. I've lived all my life in Melbourne, with them off in the distance. My parents, however, are from Italy, bordering Austria, Slovenia and other Italian regions. When over there, we took a day trip into Austria (a very strange concept for an Australian) and the mountains you see as you pass through the border regions are just breathtaking. Like nothing we have here in Australia. I'm used to our non threatening "big hills"😊
Very interesting info 🤔 I live close to Mt Donna Buang and give thanks to the volcanoes that created some of the most stunning scenery in the world 🥰🇦🇺
Great presentation and top-shelf datasets, as usual. Have you ever considered impact ejecta as a valid source for all of that LIP magma source and caldera formations?
As I've studied Planetary Collision Dynamics, with a heavy focus on Active-phase & Impact-phase Comets slamming into Earth, I've found that most geologists and geophysicists do not study impact physics or Active-phase comets. And, for some odd reason, most academics and PhD's believe Asteroid and Impact-phase Comets will damage the Earth's crust the exact same way? This would violate fundamental physics and thermodynamic laws if true?
I applaud your use of the "magnetic scans", are you aware that Active-phase Comets generate their own magnetic fields?
Remember, comets are not simply "dirty-snowballs." Comets are Space-mountains of SOLID Rocket-Fuel nestled in the Oort Cloud and/or Kuiper Belt, once perturbed from their dormant-phase, a comet will fall towards the inner planets. As the comet nears the Sun, sublimation of gases begins and with adequate mass/volume of solid gas, the comet generates a large Plasma-coma and thousands of kilometers long Plasma/Dust-tails. Occasionally, an active-phase Comet will slam into the Sun, planets or moons, at velocities > 42k KMH.
What happens to all of that atomized H/O/C/N/Methane/Hydrocarbons/Alcohol/HeavyMetals/Rock/dust/etc., permeates and saturates the diamagnetic cavity, coma and tails, as the impact-phase Comet contacts Earth's magnetosphere, ionosphere, atmosphere, crust/lithosphere & asthenosphere? All of this is buffeted by a Mass Loaded Plasma and Bow-Shock, building up in front of the comets path through the Cosmic & Solar Winds.
Then, the Active-phase comet slams into Earth at Mach >30. That is gonna leave a large gash and major scarring, with effects world wide, it is called Planetary Collision for a reason.
Keep digging and asking the right questions. You'll figure it out.
The deeper I got into Planetary Collision Dynamics, the more I understood the fact that there is no such place as "outer-space.", it's just, Space.
see: NASA Ames Research Center's work on Comet Shoemaker-Levy 9 impact into Jupiter, 1994. Check into plasma-physics and magnetohydrodynamics, the data is all there. Impact ejecta, what doesn't achieve escape velocity nor angle, will eventually re-impact the Earth's surface, wherever Gravity wants.
Physics is not a belief system.

Great channel man. Not necessarily looking for Oz geographies but it's so good I fit it in while researching the same kind of stuff here in Texas
This planet is truly amazing
😮 Thanks .. such great vids
Love your work ❤
Amazing video, Oz! Looking forward to the followup vid!! And look at all your new subs! Congrats!! I want some of those crystals! Wonderful!
Wonderful.
Thank you for this amazing channel. I hope it evolves in the way you want. Great effort !!! Perth
JFC! I knew we had some extinct volcanoes, but...😮
Victoria has some very clearly visible volcanoes west of Melbourne. Berwick is built on an extinct volcano, and halls gap is a massive volcano like Melbourne.
I am a Victorian and from the Ballarat area and love to hear all this . have you been to the Mt Franklin one near Daylesford? also the Mt Shank one near Mt Gambier. I have climbed it and it is amazing to look down into it. Keep up the great work.
I’m digging your channel so far.
Love your channel and can't wait foe the next episode. I would love a follow up video.
Hey I just found your channel yesterday, great work btw! I'm looking forward to checking out your other videos! 👌
Definitely worth it
Good stuff m8
"I can see my house from here" - Someone from a Lego Star Wars game if memory serves correct. Anyways, the Nongs is the shortened version of the nickname. They are the 'Ning Nang Nongs'
States in title. Add the s. Great work. Love your content.
I'd definitely like to see that bro
Hi, Im new to your channel, loving it!! Have you any info on the Hanging rock area and The YouYans?
I'd love to see you do a piece on the green triangle/volcanic plains between colac, warrnambool, Mt Gambier, & Hamilton
(Mt Napier, Tower Hill, blue lake, Mt Eccles, Byaduk Caves, Mt Rouse, Mt Elephant)
dang! there is so many!
Could the amount of Volcanic action in Victoria have weakened the Ozone Layer over Victoria and Tasmania millions of years ago..as l can't think of a reason why the Ozone Layer would have the damage it has over Australia. We are a small populated country. We could not have caused the pollution to damage to the Ozone Layer.
guess i'm going to have to sub to you, we're the only one's giving any Australian specific geography content ;)
309 liked mate, love you're work. You deserve 100k + subies.
We got another south in the city of Launceston in Tasmania.
It would be great if there were videos like this about the mountains of the Scenic Rim in SEQ, Bunya Mountains and Canarvon Ranges!
czcams.com/video/3avWNHoEDAg/video.html
He already did 👍
@@amazonmang-ck3ws ok, haven't looked through the videos enough yet. Thanks.
@@amazonmang-ck3ws I can only find videos on the Glass House Mountains and the Tweed Volcanoe. There is a lot more mountainous areas in SEQ than that.
Is it possible that these caldera & supervolcanoes are under the influence of tectonic movements? It's almost like Australia might have been spun around by your depiction. I'm talking specifically about the ring of volcano eruptions.
Volcanoes. Nature's nukes.
They're more like nuclear reactors than nukes, but yes.
I would love to see more! can you have a look at tallarook victoria
Shows that even geologically everything important in Australia happens in the south east.
I would love to have your enthusiasm to investigate my country.
Man, I want to learn more!!
My fav subject Australian volcanos. Can I come when you go visit them? Would love to see them ❤❤❤
All that silica that became opals later came from somewhere.
There's a volcanic area near me in Victoria, they call it the lakes n craters, and the stoney rises where there is lots of igneous rock around. Near Camperdown and Colac
Can you do one of your volcano videos on Coonabarabran?
2:26 The real reason The Kiwis got rid of their air force: "Ok Bro. If you don't support us from above we will wreck you from below!"
If you do go out inte bush looking for these super volcano's..... can you take Dan Andrews with you...... and..... you know..... leave him out there
Hey mate, question for you, Have you been following Nick Zentner in Ellensburg WA?? He's just East of me on the other side of the mountains from me
I was wondering if you could tell me if Mt Kosiosko has a caldera
Well, I am not a Geologist, but find it very interesting about Victoria past!
I still reckon Mount Buffalo was a volcano once upon atime.
Also find scrapes (round circular in shape and slightly slanted to hold water),in the granite boulders possibly from the Ice Age?
Does anyone know if the people behind OzGeographics are Geologists? The channel claims to discover stuff every second video and Im concerned that it may be a hobbyist talking beyond their expertise....
@@francistaylor1822 OzSpeciographics mightbe lol
I live at the base of Buffalo, it's always been known to have been a volcano to my knowledge. That's what I was taught anyway, we've studied it in science classes ever since I was a kid.
@@francistaylor1822 Oh well, It's very informative and the presenter is a qualified geologist, or maybe not!...ask him. :)
@@tragicvalentine
Mt Buffalo (granite) isn't a volcano but it was formed underground by magma pushing slowly up from the mantle, so it is plutonic rather than volcanic. It has been exposed by weathering and erosion over millions of years. Something I remember from geology 101.👍
Just a question is the strezlecki range and latrobe valley which is rich in coal part of a volcanic base too
Gotta say loving your content, just hope you don’t burn out by doing too much too quickly!
One thing I wanted to point out, it’s hard to tell which videos are related, you might wanna do what other channels do and add a bar symbol ( | ) and the series name and episode number to the end of the video titles in your multipart videos so it’s easier to tell on a console or mobile device which video is related to other videos, especially if you’re doing compilations like this one. Just wanted to suggest that as you’re doing an awesome job and it may help you out a ton.
Great idea! I'll try to get that implemented today. Thanks for the suggestion and for the amazing support!
What was the scale of millenia this all was from compared to the various Dinosaur era's ?
Can't wait until you do Far North Queensland's 'recent' volcano's and more.
come to Qld the Scenic Rim is a one Massive caldera
Whats going on with Daylesford Hot Springs?🙂
13:48 WIllimigongong That's a cool name
Question, I'm a little confused did all those volcanoes occur at the same time, or at different periods
I so want to see Melbourne, whether I’d leave is another story
Could the new findings of earths core stopping its spin cause more valcanos to erupt like we’re seeing more quakes now and I’m thinking their may be a link between these happenings.
Look at lake gordon in tazmania, it looks like it sits in the center of a MASSIVE caldera.
30:00 and 30:44 Would you please tell where those area are?
I was delusional in my regards geological knowledge of Victoria Sir OZ 👌 Basically you have packed my lunch box & sent me back to geology kindergarten 😂
I always thought that the orogenous zone was closer to Tassie
Check Sunbury out we are surrounded by 4 mountains I was told that it used to be a volcano?
Question: your map shows several calderas near each other isn't it possible that they are all ONE caldera not separate
Great video but is this the only place in Australia where we had volcanoes? surely not. By the way I noticed you are no longer using patreon , I checked the other day to see if a payment had gone through and was surprised to see nothing except the OzGeographics logo.
Yup there are but Victoria is my home state so many of the videos will be centered around here until my content is exhausted haha. I wrote a community post regarding the patreon, we originally stopped it after we made the gold discovery because I wasn't sure if I was going to be able to live up to the expectations of the people who so generously donated and supported the channel as a result of the sporadic nature surrounding the discovery of the reef.
@@OzGeologyOfficial No worries mate.
Miles in both the uk and usa
You shouldn't play up the SuperVolcanoes because it makes the average size Volcanoes feel inadequate. Its twue.
So I lived one time right on the top of a 365 million year old super volcano when I had a house at Mt Evelyn.
Did Warburton Ranges have a super volcano

First time for everything...? Lol😊
@@FlattardiansSuck Yes I am new to CZcams. Never even knew about it until tonight.
It's amazing how the remnants of these beasts hide in plain sight. The American state, New Hampshire is a prime example. Called "The Granite State" it should be dead obvious that it had an amazingly volcanic past, I mean granite, right? The ghosts of crazy big overlapping calderras are now visible to modern scanning, but still, GRANITE STATE! Great Rock hounding is a given.
BTW, love your content, you're the Australian Nick Zetner.
AND, since my age and income makes me peak value, I soldier through all the ads. You're welcome
Aren't these supervocanes in Victoria extinct.?
Dormant = asleep - not all are extinct. The last AUS eruption was 5000 years ago at Mt Schank S.A. Near Mt Gambier.
4:40 pyroclastic flows ,,everyone knows Pompei ,,Hurculenium was across the water ,,
Leidenfrost effect sped the flow up to nearly the speed of sound,,,naah like 700km/hr ,
as big as a nuke,,btw ,, i put 20 bucks into , Level Smellbourne for the gold ,,
love your stuff ,,keep it goin ..
