I really appreciate your efforts Clive to pull all this together in such a clear exposition. Well done.

Great live footage and animation, with not only Aussies but a Cubana too- the patterns and poetry of geology! Watching this has helped me understand what I have seen on the other side of the Pacific rim, as well as along other older mountains on the east side of N. America. Poetic justice in the linkage between the gold rushes of California and Victoria, and now I'm dreaming about the flow patterns of our living planet.

I don't know the geology of your area well enough to say why there's no orogenic gold but one of the factors in producing orogenic gold is the temperature of the metamorphic fluids. Recent work suggests that if the fluids reached temperatures greater than about 550 °C then this is bad for gold. There are many places in Western Australia that had just the right conditions and temperature - maybe your part of WA was not one of them?

@@GeologyFilms that is very interesting information thank you. Since I posted that comment I have been researching the Donnybrook Goldfield. Your videos let me see that it is likely orogenic. It's a 12km epithermal quartz vein structure emplaced into sedimentary layers and associated with extension faulting from gondwana breakup and Bunbury basalt evolution. Specifically the sediment basement is gneiss and amphibolite. What I've read and seen first hand strongly resembles the process you describe.

Are the Warrumbungle Ranges included in the Macquarie Arc? Or are they from a different volcanic event?

@GeologyFilms

3 жыл бұрын

The Warrumbungle Ranges are a much younger volcanic event less than 20 million years old. The Macquarie Arc which is nearly 500 million. It's interesting that there is a group of young volcanoes running down the east coats of Australia from Queensland and Victoria.

Yeah and no explanation why the subduction stopped. Well, the pictorial schematic is backwards. The Gondwana side slid over the subduction zone going eastward. It overran and consumed the subduction zone. The same thing occurred in North America where the North American plate moved fast to the west and overran the Pacific Subduction zone from San Francisco, southward, but not to the north. The changed into the San Andreas fault as plates started to slide against each other instead of override one or the other.

Did the Keweenaw Peninsula's Copper Country deposits form in the same way?

@GeologyFilms

I think there is still debate about the origin of the Keweenaw deposits. One leading idea is that the copper was concentrated by "burial metamorphism" of a thick sequence of basalts. This sounds very similar to the way that orogenic gold forms.

6:30 in, still no idea why the Macquarie Arc is there. I'm sure this video will have the answer. Yet "Geology Films" are good at no letting-on at this point in the story, I'm sure if I keep watching I will find out. lol

i just found this late at night. very enjoyable. i have some questions. at 2:56, you say "no evidence of volcanic activity". of course there is lots of evidence of volcanic lava flows in victoria to the west of melbourne, scoria fields around colac and the red scoria mt fraser north of melbourne just east of the hume freeway. and at 12:57 your map shows sandstone all across victoria. there must be differences in the sandstone across this area because there were no sandstone deposits around melbourne suitable for the elaborate construction of banks and other buildings in the 19th century melbourne cbd. the sandstone that was sometimes used in these buildings came from sydney. at least some of the volcanics in western victoria are likely to be younger than the macquarie arcs. the western victorian aborigines have legends of active volcanoes. i have seen somewhere that there were hot spots deep below the surface that move relative to continental drift and that a volcano may appear in bass strait off the coast of warrnambool. your show raises the thought in my mind that the macquarte arcs in nsw may have a relationship with the concentration of gold into monster-sized nuggets that victoria was famous for and that there may be unknown deposits of copper.

@GeologyFilms

Жыл бұрын

Good questions. I should have said "no evidence of volcanic activity at the time of the Macquarie Arc". The volcanic rocks across the central and western plains of Victoria are much younger, mostly less than 7 million years old, compared to the Macquarie Arc volcanic rocks, which are more than 400 million years old. The young volcanism in Victoria is not obviously related to plate tectonics - it's a type of intraplate volcanism. The Macquarie Arc volcanism has all the chemical and physical characteristics of subduction related volcanism caused by plate collisions - so very different environment and timing. Likewise, when I mention the sandstones I'm talking about old 400-480 million year old rocks, which form most of the bedrock of Victoria. This bedrock is, in places, covered by a thin veneer (20 to 100+m) of the young 7Ma volcanic rocks. The story of these young volcanic rocks is itself, very interesting - they are so young that western Victoria is still regarded as an active volcanic province, the last eruptions having occurred < 15 thousand years ago. Thanks for watching.

Played tectonics did not create those rocks. The came from the superplume blob that resides in the mantle transition zone (410-660km deep within the Earth).

Many years ago a scientist said a hot spot developed in Heard Island and gradually travelled to Tasmania and up the east coast of Australia and is now under Rabaul Harbour, it last erupted in 1994. What caused Gondwana to break up into the tectonic plates we have today. did another planet crash into Earth?

@GeologyFilms

3 жыл бұрын

The reasons for breaking up a Supercontinent, like Gondwana, is a good question, but not my expertise. Some people think 'plume push' may contribute, or something called 'subduction retreat'. These effects would weaken areas of the crust so that fragments can split off along the weakened zones and thereby start the process of breaking up a large continent.

Interesting that the basalt with the white crystals appear to be exactly like what is found in Northern California. The local rockhounds call it Chinese writing stone as the crystals look somewhat like Chinese crystals.

Yes it's interesting how rocks often look the same in different continents and that's because the geological processes are the same or similar. The white crystals will probably be feldspar.

It's a really good question but I'm not sure how well I can answer you. The ocean floor does get deeper along the edges of subduction zones. The other thing to consider is that as the rocks in the Andes or Himalayas are being compressed, they are not only being pushed up but the whole mountain region is becoming thicker - the thickened base is often referred to as the mountain's roots.
