5:25 Actually funnily enough continents *can* sometimes overlap IRL during a tectonically fast subduction zone margin collision. Seismic tomography has revealed that in the case of the Himalayas continental subduction has occurred corresponding to roughly 50% of the original Indian sub continent. The main difference is that when this happens neither mass of continental crust sinks down into the mantle rather instead they pile up on top of each other. In the case of the Himalayas this zone of overlap is what we call the Tibetan Plateau. The plate boundary for this ongoing collision still has the same architecture as a normal subduction zone. The scale is pretty amazing As for other comments last weekend during Nick Zentner's livestreamed Baja BC series interview/discussion with Karin Sigloch & Mitch Mihalynuk there was a section where Mitch Mihalynuk showed some G plates animations which might be interesting for anyone who wants to take a look at a reconstruction of the complex collisions to form the modern West Coast of North America. The video Section was titled : R. Fixed Archipelago ... with Karin Sigloch & Mitch Mihalynuk The animation involves North America ramming into a mature volcanic arc complex after rifting apart from Pangaea during the Jurassic to Cretaceous time period and it is based on paleomagnetic seismic tomography and geochemical/geophysical lines of evidence integrated together. I particularly want to bring attention to the formation of Alaska with volcanic arcs getting folded up into each other its quite breathtaking even in a simplified animation.
Once the gplates section has finished, will you do a walk through of the main geological events of the world you commissioned or are you going to jump straight to the climate and biomes? Will you show how the climate changes when big events happen (like two continents meeting or splitting)? I don't want to overwhelm you. Just curious about how you will structure stuff. Go at your own pace, we'll watch it all :]
LIPs are a thing I think he's going to cover and orogony. Climate changes are not only related to geological changes but also o2 levels et all. Having a full and truthy climate history would be an undertaking of imense coordination between factors. Cool AF, no doubt.
@@stephenrider6107 LIPs will frankly be difficult albeit fascinating intervals to approach for worldbuilding in part because they have such dramatic consequences for life on Earth with each one being associated with a mass extinction event of some degree. That said their impacts seem to vary quite a bit depending on the when and where the eruptions occur and its hard o reconstruct such eruptions when the last "real" LIP either occurred 17 Ma (if you count the Columbia River Flood Basalts) or ~30+ Ma if not. Another big factor in geological time is carbonate reefs as while they have convergently evolved many times the reef builders have been different each time and moreover there have been long intervals of time without massive carbonate reef complexes In particular during the Triassic and early Jurassic reefs like that didn't exist as reef builders were utterly devastated by the preceding End Permian mass extinctions a.k.a. the great dying. In that sense what the large ecosystem building flora/fauna of forests and or reefs have been built by different organisms over different geological periods its kind of tricky to generalize. Would be amazing to see done in worldbuilding though I thought Biblaridion would cover this at some point but he never really did
Yes! Once the Gplates section is finished, I'll show yous the finished planet and talk you all through then geological history and associate climate events before we tackle modern climate mapping, ocean currents etc.
Not every LIP leads to a mass extinction. LIPs occur about every 30 My. The last mass extinction (not causes by humans or a meteor) was the end-Triassic extinction some 200 Mya.
Are you planning to use this example in later steps or will you make a full simulation for that? If you do the latter, perhaps you could do it as a timelapse in the background of a quick review and a discussion of what's next.
If you check the earlier videos I _think_ I remember Edgar saying that Nikolai from Worldbuilding Pasta was doing a fully-sized, fully-detailed, full bells-and-whistles one for future tutorials to be based on, and Edgar was doing this barebones one as more of a limited demo/highlight reel
Every f*cking video, I think that it can't get nerdier than that And then some guy writes Edgar with a bunch of scientific explanation for how to calculate things😆😆😆😆 Love it!!!!
At 12:15, I think you made a logical error. You say that the island arc is 20 Mya, but that is the moment since you have drawn the island arc. The convention from an earlier video is that we only draw the island arc once they are 50Mya, as before that, they are basically nothing (as you calculated). That does mean that for the calculation of created terrain, we should take our start date as the moment the subduction zones have gone active. That is the moment when terrain starts appearing. So your calculation should be: 900km * 70 My *.5 km/My = 31500 km². This also counts for the other accreations, which should have 50My extra.
My thinking is that for the first 50 million years, island arcs are basically all underwater. After 50 million years the island arc grows above sea level and its those bits that glom onto the continent. So your 31,500 km2 accounts for all the terrain created. Whereas my 9000 km2 accounts for the above sea level portion of the terrain that gloms onto the continent. Now, I'm not a geologist and I might be (probably am) way off here. But this feels right to me. Imagine we have a 1000km subduction zone open at 100 Mya and then 50 million years later a collision occurs. If we take the starting point to be the opening of the subduction zone we get 1000km * 50 My * 0.5 km/My = 25,000 km2. It would feel really weird to add 25,000 km2 of continental crust from an island arc that is basically all underwater. Under my interpretation, we get 1000km * 0 My * 0.5 km/My = 0 km2. All underwater, basically nothing added to the land. I dunno, thoughts?
I've been playing with GPlates and coming up with my own processes for when these collisions take place so it's interesting to see the differences with how you're doing it. One thing I noticed is that you made the same mistake as me in referring to accreted "terrains" when the correct spelling is apparently "terranes" in this context.
Forgive me, but aren't "cratons" something that are defined in retrospect? Like, "this part of the plate was always consistent so we call it a craton" rather than something that was ever intentionally preserved over time?
I think the idea from a worldbuilding perspective is that we want to have consistent cratons in our present-day world, so we define them from the beginning and fudge plate movements to keep them untouched. I'm sure that's not the only method of making cratons, but it seems like it should work well enough.
@@SpuneDagr Most of the major cratons on Earth have remained stable for over 2-3 billion years as far as I know, and since this simulation is only capturing the last 1 billion years or so the cratons should already be defined.
Yes exactly cratons are defined based on modern context though it should probably be noted that there are some geochemical/geophysical distinctions between Earth's Archaean age cratons and younger crust. Currently IRL there are several modern examples of ancient Craton destruction which come to mind for example the Colorado Plateau is a section of the Laurentian shield an extremely ancient major craton which is getting torn off North America by an underplating thermal upwelling which is contiguous with the East Pacific rise. Notably this appears to be the way nature makes "grand canyons" as magmatic upwelling of rigid crust which is able to hold together during that uplift is really the only force that can push that large amount of land upwards on short enough timescales to build huge deep canyons before erosion can tear them apart. The only other example of this kind of complex canyon is in the Southern section of the East African rift valley. Then there is India where not only is ancient cratonic rock being destroyed its getting subducted. Frankly only a few of Earth's cratons have survived relatively unaltered to the present day.
You know, your comment made me realize that you could do the entire worldbuilding process without using cratons. I think it mostly helps by giving a reference for your plates. For example, if you chose 9 cratons, you know you'll have 9 major plates + some microcontinents floating about, and it's easy to figure out which plate id each should have. But yeah, I don't think it is necessary to do a simulation.
Hi, haven't watched the video yet, and now you launched me into GPlates, so now I can go using worldbuilding pasta's work to do my simulation, 350ma now
Important : when coupling continent, you need to reload the rotation file before resetting the anchored plate to 000, otherwise it gives you weird stuff
How does the size of a planet affect the speed of tectonic plates? Say, a planet 0.5x the radius of earth. The kinematics tool assumes the planet is the size of earth, so if it says 3 cm/year that's not really accurate for my planet. Do you have any idea as to what I should do?
I wouldn't worry about this and just go with the same speed for any given Earth-like planet. Though not 100% accurate, it's a reasonable simplification to make imo.
@@Artifexian Follow-up question: should I scale the other things down (craton size, accreted terrain area, etc.) in this way, listening to the measurement tool with the default radius? I know that's not entirely realistic either, but it seems more consistent to have everything scaled down than just some things.
@@lucas_e_jones I know this is a late response, but you can actually change the radius of the planet you are working on in the measurement tool, allowing it to give accurate measurements based on the actual dimensions of the planet you are working on.
My plat ID isn't linking and I don't know what I'm doing wrong. i did the steps and nothing breaks, but then nothing links either. Has anyone had this and figured out how to fix it? Both parent and child were once following other plates, is this the issue?
Sure! You'd lose some of the benefits of the tools GPlates provides, like the kinematics tool and the colour by age functionality. But yeah, you could in theory even do this entire process with a ball and bits of paper.
We'll talk about this in the next video but, in short, it's being rammed by the ocean crust due to different rate of plate motions. Think of it like a snow plough rear-ending a car. Both are travelling in the same direction, yet upon contact the snow plough "subducts" under the car, and the car is "uplifted" by the snow plough. And this convergence can continue to occur even as both continue to travel in the same direction.
@@Artifexian love the intuitive explanation, but I do hope to see more in the future video :) the difference in rate of flow is different between two oceanic crusts because one is pushing a continent; this gives us the subduction zone, correct? Could you, in a hypothetical scenario, shape pink continent to be a giant right triangle with the leg perpendicular to the rift valley and have multiple subduction zones as the triangle moves away from the rift? I.e. the region between the rift and the tip of the triangle only has to move a small amount of continent, but the region between the rift and the base would have to move a LOT more continent? Or have I misunderstood the mechanism for subduction formation between two oceanic crusts. So this: | |\ | | \ | L....\ | Becomes this over millions of years: | _._._._._ |\ | _._._._ | \ | _._._ L....\ | _._._._._._._
Regarding the leftover subduction zones and island arcs (particularly the large one) behind the two colliding continents, could you rotate the 100 continental and ocean plates counter clockwise a bit during the early collision period, like the subduction zone is still active? Or does it pretty much die once the continental crusts run into each other?
uneven pull is fine and as Artifaxian alluded, you could continue to have the two continents grind against each other, likely creating a rift valley towards the north.
Just as a curiosity, could the collision re-activate and rip open the failed fault line in the light-blue craton? Or are the forces too "slow" to push it into activity?
I'd suggest you abandon the term "island arc" and instead use the term "oceanic arc" as this better differentiates between the types of magmatic arcs. Oceanic arc are rooted on oceanic crust and continental arcs are rooted on continental crust. New Zealand is an island but is a continental arc. Kermadec (the northern extent of the New Zealand arc) is an oceanic arc.
I'm sorry to write this, but I'm very disappointed in that this series started out so well, and now it's just turned into a GPlates tutorial 🫤 You should definitely do the kind of stuff that makes your nerd senses tingling, but keep it separate from this series. I loved to watch your older stuff on world building! 🤓
I'm sure it'll go back to the old stuff once the technical details are out of the way. I think this is the last or second-to-last video focusing on a GPlates tutorial, given that he ended by saying that he covered all the scenarios we're likely to encounter there.
But the point of the series is to show the whole process of world build, how to simulate plate tectonics included. I agree that he could have shorted the gplates section a bit. Some things seem to be doubled. But it only takes a relatively large part of the series right now (7/16 still counting) because working with gplates seems harder to explain and more involved than filling out his nice spreadsheets. As far as I understood his intentions, he doesn't have much more to show in gplates, maybe 1-3 episodes. It's not like he commissioned someone to do the detailed whole process, so he can keep the tutorial shorter and focused or something. In the future there will be more long, maybe 10+ episode segments on spec bio and conlang and so on. The gplates section may seem long now, but it probably won't in the future. In his own timeline (ep. 0) he said it may take 3 to 5 years. He made 16 videos in 6 months, so 90 to 160 episodes are possible, what are 10 or so episodes on gplates compared to that.
This whole series is a tutorial! This is world building using his building philosophy. He's big on realism. So every step of building his world will be guided by a more realistic approach. So he built a feasible star system and home planet. A feasible geologic history with world building pasta and showing us a very simplified version of it because of how in-depth gplates is. We're already done with collision demonstrations and we already know a lot about different plate boundaries and how they move and form stuff and destroy stuff. I'm sure he's nearly done with showing us the basics of plate tectonics (moreso after the negative feedback like yours made him decide to futher simplify and reduce this phase) and we'll be off to the races in the next phase. Once this phase is done I bet he'll show us worldbuilding pasta's work on the geologic history of Artifexxia which will probably just be playing the completed animation of that world with some commentary and that'll be the end of plate tectonic building (unfortunately). I wasn't happy with the effect feedback like yours has had on the series as I was very interested in seeing his original vision for this phase playing out, but what can you do I guess? This is only a small part in the overall world building of Artifexxia, a rather important part, as you'll see later, but in the grander scheme of things this series will have much much more to it than just gplates.
I would like to see you do a full world at the end of this, from start to finish, with full complexity. This is all extremely interesting, and I intend to do one of my own when you're finished with the series.
I believe he contracted someone to do a full example, I remember seeing it in the first of the gplates episodes

I'm sure it'll go back to the old stuff once the technical details are out of the way. I think this is the last or second-to-last video focusing on a GPlates tutorial, given that he ended by saying that he covered all the scenarios we're likely to encounter there.
But the point of the series is to show the whole process of world build, how to simulate plate tectonics included. I agree that he could have shorted the gplates section a bit. Some things seem to be doubled. But it only takes a relatively large part of the series right now (7/16 still counting) because working with gplates seems harder to explain and more involved than filling out his nice spreadsheets.
As far as I understood his intentions, he doesn't have much more to show in gplates, maybe 1-3 episodes.
It's not like he commissioned someone to do the detailed whole process, so he can keep the tutorial shorter and focused or something.
In the future there will be more long, maybe 10+ episode segments on spec bio and conlang and so on. The gplates section may seem long now, but it probably won't in the future.
In his own timeline (ep. 0) he said it may take 3 to 5 years.
He made 16 videos in 6 months, so 90 to 160 episodes are possible, what are 10 or so episodes on gplates compared to that.
This whole series is a tutorial!
This is world building using his building philosophy.
He's big on realism.
So every step of building his world will be guided by a more realistic approach.
So he built a feasible star system and home planet. A feasible geologic history with world building pasta and showing us a very simplified version of it because of how in-depth gplates is. We're already done with collision demonstrations and we already know a lot about different plate boundaries and how they move and form stuff and destroy stuff. I'm sure he's nearly done with showing us the basics of plate tectonics (moreso after the negative feedback like yours made him decide to futher simplify and reduce this phase) and we'll be off to the races in the next phase. Once this phase is done I bet he'll show us worldbuilding pasta's work on the geologic history of Artifexxia which will probably just be playing the completed animation of that world with some commentary and that'll be the end of plate tectonic building (unfortunately).
I wasn't happy with the effect feedback like yours has had on the series as I was very interested in seeing his original vision for this phase playing out, but what can you do I guess?
This is only a small part in the overall world building of Artifexxia, a rather important part, as you'll see later, but in the grander scheme of things this series will have much much more to it than just gplates.
