The Great Dividing Range is the fifth longest mountain range in the world, and it exists in Australia, of all places. Australia is pretty well known for being a relatively tectonically stable continent, with no nearby tectonic rifting or subduction-related events occurring. As a result of this, orogenies, the term used to describe mountain building processes, should, in theory, not be occurring here. But yet here it is, this spectacularly large mountain range not only exists, it stretches from the very tip of Queensland, all the way south through New South Wales, where it then bends east as a result of some tectonic activity that has occurred here, before straightening out somewhat, and stretching down in Victoria, where it then suddenly, and, somewhat unexpectantly, turns west where is stretches towards the far western parts of Victoria, through the Central Highlands where Ballarat, Creswick, Daylesford, and Ararat occupy, before finally ending at the Grampians.
In this video, we'll get an idea of the tectonic processes that led to the formation, and continual uplift of this mountain range. We'll go all the way back to the very beginning, around 550 million years ago, and work our way up to point when the Great Dividing Range first began life. We'll also explore the weird western bend that occurs in Victoria, and discuss why this mountain ranges stretches so far west.
New Zealand, unsurprisingly, has some part to play here. But, a fact that is perhaps surprising to many, is that so does Antarctica. And you'll understand why by the end of this video.

Thank the algorithm for leading me here! In my childhood, I visited Australia and New Zealand and was marvelled by their natural beauty, we'd spend a lot of times in the museums looking at rocks and at the mountains; so much so that when it was time to return to my equally beautiful Chile, I brought myself some thick Australian Geology books! Some years passed, here I am studying Geology in my Atacama, and finally little by little acquiring the knowledge to understand the geology of both my homeland and our distant beautiful South Pacific Neighbours! Thank you for the vid, love from Chile 🇨🇱❤️🇦🇺🇳🇿!
So glad you enjoyed this! Thank you so much for sharing this, it was absolutely awesome to read mate!
The great diving ranges were far larger then they are now. What’s left is the hard granite. Essentially the bases of what was some of the oldest volcanoes to exist.
Come back any time mate. I’ve seen so much beautiful nature and geography from Chile, but now you’ve made me want to visit on my next holiday.

thanks mate Iam an Aussie and that's 100% correct didn't have to watch the vid knowing that it was wrong
I feel sorry for the first people that looked at the dividing range and thought “screw that I’ll just walk around”
Australian here: The Great Dividing Range is not a single, continuous mountain range like the Andes but a series of ranges that runs down Australia's east coast. So you can go west.
My beef cattle station is based on the great dividing range. Our property is made up of part of the range with steep cliffs and some staggering views from the top of the range here in Queensland. Over the past 10 years myself and some friends have planted 2. Million trees on areas of the property that I've closed off so cattle came roam on that area and what was once bare farming land will again be forested land
That's great, thanks for the extra oxygen👍🤣
Aboringal people kept a lot of land and tops of hills bare.as they traveled their song lines on cleared path ways.they kept around the water holes and natural ponds lakes clear of trees.so when animals came down to water hole they could see them and catch food for the tribe.so for 40 thousand years Australia did not always have full on trees.also the clearings helped with bushfires and if Aboringals were burning off areas of land.they knew how to manage land.sometimes it's not always about planting trees.there are native grasses,bushes and wild flowers.
@juneallan4903 with all due respect where do you people come up with this stuff? I know there is a small minority of people (mainly women) who are so desperate to view aboriginal culture though this perfect, utopian lense but to do so is to ignore some very basic facts. No, aboriginal people didn't know how to look after the land, they knew how to look after themselves. There's quite a big difference between those 2 statements. We know the truth is if aboriginal people never immigrated to Australia the very face of Australia would look very very different, probably more closer to how Tasmanian forests look today. It was the act of "firestick burning" that left eucalyptus the most dominate tree in Australia as these fire resistant trees were the only trees able to withstand the burning/destruction of Australia's early landscape. .
Secondly, if aboriginals never immigrated to Australia it is highly probable that Australia would still be home to the unique megafauna that once used to roam right across the planet before human (not just white man) settlement. Through new impartial studies it is now recognised that it was not climate change that wiped out Australia's megafauna but instead the hunting of offspring coupled with the act of firestick burning and environmental destructions that led to the megafauna demise.
Lastly the claim that aboriginals have been living in Australia for 40,000 since even say 60,000 years is highly contentious. There are many scientists who disagree to this and they point to the evidence that there is clearly 3 very different and distinct forms of art in Australia, which point to 3 different waves of immigration by 3 different people's. As you know even the oldest rock painting dates to around 17,000 years not 60,000 years. As you are also aware the dot paintings we associate globally with aboriginal people only date back to the 1970's.
Anyways how you react to this information is up to you, you could get all defensive and emotional and start throwing out words like racism or you could say that's interesting information week worth looking into.
Enjoy your day.
Awesome! We need more like you that understand sustainable land management.
Sounds beautiful.. I live in Queensland now and I must say the dividing range is my favourite place to hike. Absolutely stunning landscapes throughout the state.
Myself and some friends mountain biked the full length of the GDR in 1988. We started south of the Grampians at Warrnambool and headed north to met the GDR near Halls Gap. Of cause we couldn't find roads or tracks all the time that were on the divide itself, so we rode on the nearest ones to the GDR that we could find.
We took our bikes onto the Alpine Walking Track in NE Victoria, and that was HARD going, as we had to push or carry them most of the time. One of the strange things about the GDR north of the Victorian/ New South Wales border is that NW of Adaminaby the GDR swings SE towards Nimmitabel for about 140kms before it continues on north. Another thing that lots of people are misinformed about is that the Blue Mountains are not actually part of the GDR, but are about 80kms to the east.
In Queensland the range is somewhat low and at times is really just a series of small mountains and hills. We ended our ride at Cape York and flew back with our bikes from Thursday Island.
How long did your trip take?
That is a truly epic Aussie ride.
I dont believe you.
My son Tom and his partner Tegan rode pushies from Healesville to Cape York a few years ago so it can be done
Some extras to add to this video. The "Great Dividing Range" is not a single mountain range, but a series of massifs (separate ranges), so unlike the Andes it is not contiguous. It is more like the less lofty Appalachians of the Eastern United States, than the soaring Andes. Secondly, some of the large tertiary "lifting" of the Great Diving Range is due to the East Australia hotspot (actually at least 2 hotspots; Southern Victoria and Far North Queensland) moving under it (the hotspots are more or less stationary; Australia is moving over them). Thirdly, the tertiary uplift of the Great Diving Range is not limited to the Grampians, it is extended to the Delamerian Orogen rocks as well (into South Australia, geographically the Mount Lofty Ranges and Flinders Ranges).
New Zealand is on another Continent. Where do you get your information from????
@@Oscarcat2212, To whom are you speaking?
Google it.
I am a geologist but I live in the other side of the world so I know nothing about Australia's geology. What intrigued me was the arrows and the tensions pulling away from ridges when we all know that they are decompressive and not compressive. So your explanation put an end to my doubt.
That is true, it's known as a Cordillera. But I wanted to keep this relatively simple as mentioned in the video haha. Also, the east Australia Hotspot looks to not be a hotspot at all, as seismic scans have revealed it has a shallow origin. Not a deep one. So it can't be a hotspot with this new knowledge. Pretty fascinating stuff! Thanks for the awesome comment mate!
New Guinea is a continental island of Australia.
It was cut off by rising sea levels after the last glacial maximum.
New Guinea is the geologically active part of the Australian continent.
Yup this is true.
@@OzGeologyOfficial Oceana!
@@zelwinters1981 your confusing geology with politics. Oceania is a political designation crossing over continental plates and has no bearing on geology.
BHP geologist? 😆
@@OzGeologyOfficialhey buddy if you get satellite map of South Australia on your phone or computer screen and then look closely with your 👁️👁️ s between township of yunta and edge of danngali national Park and zoom in up and down and focus very very very very clearly and you'll see if look very closely a giant lions face on head and can even see eyes ears and has a cat type snout with Maine. Got to look very closely and you'll see it! Enjoy have fun! 👍🤠🇦🇺🦁🌏👀
I moved to the UK a year and a half ago but I am starting to miss Australia really, really bad. Don't get me wrong I wouldn't have it any other way (moved here to be with my husband and start a family), but I miss driving on the long, open freeways, I miss hiking the mountains, I just miss my beautiful home country 😭
I have traveled all over the world but i just can't stay away from aus. It will always be my home. There is nothing like it.
Take comfort in that the crooked liberals are doing their best to destroy the beauty of Australia.
Promise to move back one day...we miss you! 🙂

So glad RUclips led me to your channel mate. Clear, precise and informative. Brilliant. Thank you.
I'm also glad it did! Thank you so much mate, much appreciated and I'm happy you're here! Cheers!
Here here
Glad you could find this channel grate channel
Thanks mate, another great video. Always very informative. Love your work.
Much appreciated! Thank you so much mate! Glad you enjoyed it :)
The Great Dividing Range and your channel share something in common, The only way is up. I'm extremely impressed by your knowledge and delivery of it every time I watch a new upload. Thanks for the awesome content mate! Greetings from Central QLD.
Thank you so much mate! What an incredible comment hahaha. I really appreciate the support immensely!
Hey! me too. :)
I grew up near Bacchus Marsh, but have lived in Ballarat, Horsham, Shepparton, Geelong etc in the past. The geology and geography of Victoria has always fascinated me, though there’s much of it that goes over my head. This channel is perfect, it introduces and explains things in a way that I can grasp, but doesn’t treat me like I’m stupid. I’d love to hear of any other resources anyone has that are comparable to OzGeographics?
Well done- I’ve just become a (baby) Patreon. I’ll definitely be climbing tiers as I can afford to, and will forever be singing your praise lol
By the way, the age of this planet never ceases to blow my mind. I have a Spanish piece of eight that was retrieved off a boat that sunk in 1653. When I hold this small price of metal, I honestly can’t help but be blown away at how old it is, but at under 400 years, it’s not even the blink of an eye in the earth’s history. It honestly makes me anxious just thinking about it. The world really is full of wonder!
I was like you….lived over the western side of VIC but have to say, the eastern side is so much more spectacular. A lot of Northern Europeans moved here because of it.
We are sitting on the Greater Western Volcanic Plane - a large Caldera that covers half of Victoria & Mt Gambier is one of the Volcano's expected to go off first .
Melbourne would get all of the ash and fumes.
Look up E B Boyce's media releases stating we're overdue by hundreds of years for them to go off.
The sun is also a reason we have quakes....
@@igitha..._ 🧐
Thank you so much for the kind and touching comment Dani! I've always felt the same! So I'm so stoked to be able to bring this to you. I'm pretty obsessed with the geology of Victoria, so I can't help but pump out content on the state. That piece of metal is insane though, it's actually amazing you have that...
Wow Oz, I had no idea that Australia was the most "geographically stable" continent, with curved mountain ranges, how comforting! I've only lived in geographically unstable areas, such as growing up with the massive quakes of So. California, sink holes in Baja, MX, and even where we are now, the water table rising & falling beneath our farms causes them to be a bit unstable, but it does cushion us from feeling the full extent of massive 8.0 quakes, and volcanoes, occurring along the Pacific coast, and in the middle of the Caribbean (especially bad 5 yrs. ago - so that's 1 good thing)! HA! Keep those videos coming!
Can't imagine the big ones honestly, thanks for watching as always Cheri! Hope you're well and things are safe over there now :)
@@OzGeologyOfficial We're good here, at the moment, HA!!! Hope our Aussie neighbors are drying out over there. Praying for ya'all, Oz!
Im 30 years old and live in regional victoria, i can remember a minor quake which only shook the ground slightly when i was maybe 10, another when i was 21 about the same strength. Very surprising lol
I had a visitor from Canada who said the great dividing range can't be called mountains but just a bunch of hills, lol.
It's definitely a mountain range but I definitely understand where they're coming from hahaha.
My goodness these videos are just fantastic! Did you do a geology degree or do your own study? In a few videos you have given more insight into Australian geology than I have obtained in years of random youtube videos etc.
I'm pretty sure Oz has a few geology degrees under his belt. I'll ask in patreon chat for ya. 😉💖
@@KerriEverlasting Thank you so much. I will send some money to him through paypal, I really don't like patreon.

Glad you like them! I'm just an obsessed person who narrows in on passions to the point of extreme hyperfocus haha. Most people don't get it, but some do!
Live in the southern highlands of NSW. You have answered a number of questions that have puzzled me for quite some time. We take so much for granted. Thank you for passing on your knowledge. 👍😊
Me too. The highland around here look so much like a wall a a Rift Valley, but no one before you mentioned the dead rift or the pressure from New Zealand keeping the highlands uplifted. So the missing rift was very confusing.
So glad you both got something out of this! Thank you so much for watching and for supporting the channel :)
"Relatively tectonically stable continent".... we've experienced a couple of tremors in Melbourne, very minor by the standards of our friends over in NZ, California etc and that's been enough to make me grateful I'll (hopefully) never have to experience a major one. It's a terribly disorienting feeling for the few seconds of shaking and I can't imagine what going through a major one or living with minor ones regularly must be like.
Dude that small earthquake really caught me off guard as I didn't think it was possible for it to happen there, so had no idea what it was. I remember just feeling like the world was going to end that day 😂
My grandmother in atherton on the Tablelands west of cairns exerienced an earth tremor. I do not know which year, she passed a while ago.
Thi region is very beautiful. We have natural fresh water lakes with wildlife in them called Eacham and Barrine in inactive volcano craters, with connections underground, there is also another smaller crater, so far down, narrow, crooked and deep, it is dangerous, has been scientificaly checked out. Surrounded by massive old growth rainforests. This is a tropical farming community with food festivals, farming coffee, tea, mango, paw-paw, avocado, pumpkin, potato, sugar, old tobacco farm (not growing now), dairy, with chocolate makers, wine, cocoa and other exotic fruits growers. Most things you want to see are not far away..
Yup, stuffed up on that, looks to be the 5th actually hahahaha.
Pity Australia is experiencing these huge temperature rise problems...
The Range is pretty trippy. Over the years I've crossed The Range at many locations, from Barrington Tops, Barcaldine, Georgetown, and Laura among others. The first time I crossed the range Barcaldine, I was blown away. I was used to The Great Dividing Range being tall mountains and winding roads. The crossing between Jericho and Barcaldine is not much more than a big hill.
Waterfall way from belligen to armidale is spectacular.....as is the gwidir hwy through graften to glenn innes...
@@thylacine1004 I've done the Armidale run, and the Gwidirr as well but many moons ago.
Armidale run is a mini Bolivia
Very trippy indeed! One hell of a place to travel through though. Truly incredible!
It's pretty spectacular going up over the Barrington Tops. I used to live in Gloucester which is right near the Top and it was such a picturesque place.
I had no idea that Australia hosts hotspots (Learnt this in the comments). I watched a series of lectures here on RUclips, by Nick Zentner and he mentioned that Australia was attached to North America at one point. I'm glad that you're here because I find Australian geology and paleontology are fascinating. Thank you so much for uploading.
Oh my... maybe my sub to Zetner has brought me here by algorithmic magic also.
Hey, I'm from Tasmania and I am always fascinated by the rock formations at Rocky Cape National Park... the rocks that match those near the grand canyon.
Numa was the supercontinent in play when Tasmania was just a sedimentary deposit in an ocean.
I have more questions than answers... but I'm here to learn and share my experiences.
In fact, there's a vid on my channel filmed at Rocky Cape National Park... and I have more vids planned for that location, more specific to geology and archeology.
It is always uplifting (!) for us Kiwis to learn how much influence we have on our western neighbour. An excellent video thank you 🇬🇸🇦🇺.
Like anything Kiwi, us Aussies will claim it as our own. ;)
@@Jabjabs and we kiwis will bitch about it all day and night, but then we'll still move to Oz for the better salaries and infrastructure.
@@SamuelKristopher Don't come if you're going to mention Trevor Chappell.
@@SamuelKristopher exactly
I'd been curious about the formation of the range before, and Wikipedia states on various pages that is was formed by a collision with Antarctica during the carboniferous period. I've looked for this collision in those tectonic plate animations but could never see it. So your explanation of uplift from rifting makes more sense. Thanks for the video
Thanks Greg! So glad you got something from this mate!
Great video mate! Very informative. Been all over tthe range from Qld to western VIC and all through NSW. Snow, Summer you name it. Very varied and beautiful. Well explained! Keep it up!
I really appreciate your videos. They are very well researched, have excellent graphics and narrated in a clear and articulate manner.
Many thanks, Andrew! I appreciate the amazing support mate 😊
Love your vids man keep them coming :)
Just did a binge on your channel.
Great presentations mate. Glad I found you, just recently..
I'm back to teaching secondary science this year and this material, your subject matter, is hyping up my expectations, me being an EES (the old geology) and physics teacher.
Cheers mate
Thank you so much for the incredible comment mate, I'm so, so glad you enjoyed this and that you got something from this.
As an Australian who has visited Canada I always find it funny we call these big hills mountains haha.
Just because they are old, does not mean they were not once very large mountains... As an old continent there has been more than a little erosion in the intervening millennia... The mountains of the Americas are just young mountains, still rugged and bearly eroded yet. Consider them the know it all teenagers of the geological world.... All sharp abrasive edges.
I love all of this knowledge you are sharing with us. Well done! And Thank You From Regional Victoria
👏👏👏
You are so welcome! Thank you so much for watching!
Im so glad to see this, I live in Victoria in the volcanic plains and grew up seeing the dormant volcanoes but never knew much about it all so loved learning more
I learned a lot of new things about our beautiful Australia. Thank you for your video.
I was told that the Great Dividing Range was similar in altitude to the Andes but has been heavily eroded millions of years ago due to being a quite old piece of landmass.

Mate I love your videos and as usual this one was most interesting.
Glad you enjoyed it mate! Thank you so much as always for the incredible support!
First video on this channel I've watched. Two mins in and I subbed.
Nice work, mate!
Great video mate, love learning new random facts to tell people
As a bloke who grew up in South West Vic, and spent alot of time in the Grampians, I absolutely loved this!!!
Same me I grew up near Ararat (Grampians) Geological faults clearly marked.
Glad you enjoyed it guys! Thanks for watching :D
Hamilton, I need a hand dragging a 44 full off dirty oil up Mt Napier. I just want to see what people do.
Thank you, love the info
Love the video. Cheers from the Hunter Valley of New south Whales.
Thank you so much for watching mate!
Wow didn't see this coming - wonderful video
Love your work 🙏❤️ Victorian that has lived in the ovens valley and Gippsland, now in Queensland.
Orbost being my fav place on earth. Cheers.
Great work, great content. Respect. From the Atherton Tablelands. Right on top of the GDR. I'm fascinated by the geology happening here, this content was refreshing, and inspired.
Thank you so much for watching Shane!
as some one that lives on the other side of the Great Dividing Range i hate the damn thing the weather is completely backwards on this side rain when you dont need to and no rain when its needed.
Fascinating, all the videos I've ever seen from this channel really are inspirational.
Thanks for great explainers about how we were formed. I live in Tassy now, came from Melb. I love rocks and mountains. Now my G'kids can get to know more too.
I always learn alot watching your videos. Being from WA I do now wonder how the Darling Scarp and Stirling Rangers had developed in the Perth Metro and South West Areas.
Great info, thankyou,from Nth QLD, Australia!...🐸
Fantastic once again mate! Hi from Perth WA 😃😃
Thank you so much Ellyse! I appreciate the support!
so glad to see someone do a video on the great dividing range. I grew up in SE QLD on one of the mountains and learnt a lot about how awesome the land around me was, its good to see other people learn about it too.
Edit: After finishing the video, I'm kind of sad to see that its mostly Victorian centric and doesn't talk about any of the other notable areas of dividing range (Mt Kosciuszko, Tweed volcano/ Mt Warning, Mt Superbus, Mt Bartle Frere
Congrats on 50 Videos!!
Thank you so much Tyler!
Very enjoyable video thanks Id like more 😊
Very informative and excellent presentation. 👍👍
Wow the Grampians are still growing like whoa, great video.
Would love to see an episode explaining how the climate in Australia’s interior would be different if the great dividing range was taller like the Andes or Rockies
simple, it would be even drier.
it would be drier, the coast would be wetter, maybe more rivers due to snowpack and glaciers.
Actually, the Great Dividing Range is the 4th largest at 3,500km behind the Rocky Mtns at 4,830km South African Great Escarpment at 5,000km and the longest Andes at 7,000km. But great video none the less.
Good stuff mate +1 sub 👍
Thanks for the sub!
More detailed, longer videos are ok with me. Very interesting.
I had to watch this again as it is so interesting. I catch the city to Dandenong train and on my left are the Dandenong ranges and on my right is Mount Aurther. I would love to know more about these including Mount Matha.
Excellent video
Absoulty love this guys research
Spot on awesome
Thank you kindly!
Great video. It is interesting to look at the relationship to the Victorian Gold Fields to the fault zones shown in this video at 5:37
Great stuff
great editing and narration. keep it up
Thanks a ton!
Thanks for the video it's great to see how it was shaped.
My pleasure! Thanks for watching!
I remember being told in school that it was due to Australia passing over a magma hot spot that currently is near Mount Gambier, the possibility of a volcano occurring offshore of Mount Gambier within the next couple of thousand years is highly likely.
Very possible and it will almost certainly happen. Thanks for watching Dale!
I always wanted to drag a barrel of oil up Mt Napier, near Hamilton. About 100k east of Mt Gambier. And set it on fire, just to see the publics reaction.
@@goonbuggy1135 hahaha I like your style 😉
@@dalehatton6965 But you know a hill and a heavy 44, Lots of effort, But itid be a huge laugh. Might be easier to put it in the Byaduk caves.

Excellent video 💪
Thank you 🙌
Awesome Awesome video ❤
Glad you liked it Audrey! Thanks so much for watching :)
Finally! I've been getting skeptical of the algorithm but for the first time in a while I'm totally happy. Liked and subbed.
Only one thing - I've got no idea what "compressive tension" is. Maybe this channel is aimed at more knowledgeable geology enthusiasts and that's okay, still enjoyed the video. But it was a bit hard to see how this rifting could still lead to upward movement in Australian mountains.
Thanks Samuel! Certainly is confusing to say the least. Essentially the middle of the rift zone is splitting apart, and this split in the middle is causing magma to rise up through it en masse. This magma rising is forcing the plate to further rift and to split apart, and in time, the sides of the rift zone take on the majority of the stress that is forcing the plate apart. In time the sides of the rift zone become squashed as the rift further spreads apart and they begin to fracture, buckle, fault, and uplift as more and more stress gets applied to them during the course of the rift zones' life. It's definitely hard to explain in words, but I hope that helped :)
Can you make a video of Queensland, around Mount Samson and north through the Glasshouse Mountains, and explain that amazing country, please?
I'd be interested in seeing a video about that, too. The Glasshouse Mountains are impressive. I'd also like to hear about the Granite Belt - used to live up that way and the amount of granite, basalt and even pumice lying around the place was incredible.
This is really interesting and informative. Thank you. 🇦🇺
Thank you so much for watching, Stephanie, I'm so glad you enjoyed it!
Wow, very cool....
Crazy how geological activity here in NZ can have such an affect on Aus
Agreed!
fascinating, informative, ...
I live in Far East Gippsland near the Black Allen line on the south side of the bend in the great dividing range at 250-350 mts, on a sheer zone with granodiorite bedrock and the occasional basalt overlay which really looks like an intrusion and gets me confused. I am fascinated by the geology and rocks on my property and the greater surrounding area. The river along my boundary has such a variety of rocks coming down it and i often like to look at them and wonder how far from upstream they have travelled, i also think that there is a volcano a few ks north of me, just from looking at the google earth maps. . Great videos thank mate although sometimes i think you talk too fast and i cant keep up.
Thanks for sharing mate, I share that same fascination and love. I'll try to slow down a little, too!
Old geologist here…enjoyed the show!!!
Many thanks, Janet! So glad you enjoyed it!
Great presentation! So great to see Australian videos on this topic for a change.👍🍻🤠
Glad you enjoyed it!
Agrees with what I've read about rising lake St George near Canberra.
Thank you for the video. It is very informative.
It is interesting that you have mentioned the Great Diving Range starts in North Queensland, I was told at school it started in Papua New Guinea and further to this, it went down across Bass Strait (quite shallow waters hence it become quite aggressive in windy conditions) into Tassie. This was 50 years ago, I hope things have been upgraded since then. It is worth mentioning there are numerous points along the Great Divide where there has been serious historic Volcanic activity, this would weaken the Crust?
Still an excellent video, thanks for the effort.
Cheers Adrian! Tried to keep this one simple and onpoint, I have other videos where I explore the massive volcanism that occurred here :)
I will look into these.
Thanks for the Work, it is very informative.
Very cool
Would like to see a similar video about the origin of the Flinders Ranges in South Australia
Actually the first 100km west of the range is different soil to beyond that, the actual split being around the Albury/Wodonga area traveling north and south.. fault lines from Wagga to Albury and down into Vic Beechworth. Running a north south direction. That eastern section of Australia drifted into the central and western. There is seashells in piles on the western foothills of the G.D.R.
It would be good if you could put the text at the top of the page so we can read it under the RUclips controls. when we pause it.
Great video. Can you do South Australian mountains please
Thanks Dan! Sure thing, I'll add it to the list!
Nice, I've always said that we're limited to very few natural disasters and the fact we have such a massive mountain range on the East was always a question up in their among mates, cool bit of perspective.
1:43 has some interesting cliff erosion patterns I noticed, it looks almost like water cutting into the side of the ravine consistent in height around the entire basin and stepping down in stages. I've been learning about North America's landscape as it's been ravaged by flood disasters and it has very similar features. The only clear difference from evidence I've seen for myself is that they had a glacier sitting on top of Canda to prompt that flooding and now an impact crater in Greenland that's been dated to the YDIH at 12,000 years ago, and also a smaller one south in Canada dated 8000 years ago.
Thank you so much Josh! Will do mate :)
Hey mate another great video. Love to see one on the separation of India from WA. We have one of the most active seismically active areas in Australia that runs through a place called rocky gully. There are occasions of earthquake swarms, one a few yrs ago that caused a surface rupture in a dudes farm.
The Bunbury flood basalt is also really interesting as it powered a hydrothermal circulation cell involving a failed third arm of the rift zone.... and an epithermal gold system that I'm about to study as a Masters project.
Animations of the break up of gondwana always helpful but not much focus has been given to understanding what happened here. We have the darling fault which is western edge of archean yilgarn craton, then the failed rift arm which pulled the Leuwin/naturalist block off the yilgarn. This blockis now separated from the yilgarn however, the Bunbury basin contains sedentary sequences up to 10 km deep... confirmed by so oil exploration
Very very interesting area
Keep up the great work
Cheers mate! Great suggestion, the India from WA one is definitely something I want to do for sure!
That's neat so the Great Dividing Range acts as a sort of pressure release for plates interacting and subducting all the way over in New Zealand due to an ancient fault line above where the subducting plate has already dive'd hundreds of kilometres below the surface. I wonder if the fault line's existence helps reduce severity of activity through the Tasman Sea area.
The drive from Kathrine in the N.T. to Broome in W.A. is a must for anyone interested in geological formations. About 500km from Broome is an expanse where the road skirts along sections of cliff face where a pronounced line of erosion seemingly indicates an epoch where the sea level was much higher (or the landmass was much lower) This is supported by a landscape which is very plausibly once an ancient ocean bed, where nothing much grows higher than head height and the grounds surface a flat expanse of nothing much at all.
Great video. I live pretty close to Mt Arapalies in western Victoria, and would like to know a bit more about its formation.
Cheers Luke! I'll add it to the list!
Thanks for showing gordonvale my hometown at the start of the video
No problem 👍
Thank you
Fantastic.
Many thanks! So glad you enjoyed this!
Very awesome ❤
Thank you! Cheers!
very informative video but would really love to see more graphics (cross sections perhaps) on how the subduction is impacting the growth of the mountains. Really hard to visualize when you use top down satellite maps that dont really show distinct mountain ridges.
Finally something discussing the Great Dividing Range that includes the Grampians! I may be biased as I live here but it’s definitely one of the greatest places in the country.

Glad you enjoyed it mate :)
I love your content ...
Thank you so much!
your videos get better and better
Thank you so much Paul! I appreciate that mate!
@@OzGeologyOfficial very informative can’t state how much I like seeing a new video on my feed
I'd love for you to do an episode on Point Lookout in the New England National Park in NSW. My understanding is that it used to be a 5000m high volcano. Several rivers radiate out in all directions from the centre former vulcano - The Styx, Bellinger, Georges, Guy Fawkes, Five Day creeks/rivers and several more. There is also a remnant of the caldera called 'The Crescent' visible from the 1478m high lookout.
Thanks Tony! I'll look into it!
@@OzGeologyOfficial That would be great! Unusually, both The Styx River and Georges Creek start flowing west then swing round to the east. The assumption is that they originally flowed down the western face of the vulcano. The Styx, Guy Fawkes and the Georges have all cut massive gorges since that time.
@@TonyGrant. the reverse of the Castlereagh river, which flows east before turning to flow west. It has been surmised that the creation of the great dividing range caused the change of direction
@@savagexeno2549 That's interesting.
I think it's actually closer to 1580 MTRS.. point lookout.
At the closing of the video that has the patreon and PayPal links, there is a drone shot of a walkway across the top of a mountain. Where is that located? It looks like a nice spot, and I'm guessing you've done a video there. I'd like to watch it if that's the case.
