Hey all! Going forward, for each video, I'm going to summarise any pertinent comments, corrections & feedback yous have in a pinned comment (like this one). The pinned comment will be updated for a couple of days after the release of the video.
This is kinda an obvious question, but what's after ore deposits? Spec evo I imagine? Since you aren't going to tackle coastal features. Anyways, your rock map looks amazing, Ezri looks like a Van Gogh painting, and I like that!
I disagree with composition of Laramide type mountains. They are more like a mix of Himalaya and Andes. You have big plateau surrounded by ridges from both sides. Ridge in the continental interior is the one which is volcanicaly active, because subduction is shifted into continent's interior. Not to mention these mountain types are generaly less volcanicaly active. Rockies are mostly composed by older plutonic (which are usually felsic, so granite or granodiorite, diorite isn't that common) and metamorphic rocks + sediments on the plateau, rather than extrusive rocks like andesite or rhyolite. Rockies are no longer volcanicaly active (except for Yellowstone hotspot area), so you don't find there much of andesitic rocks. That big andesitic are you showed is in Sierra Madre Occidental which still have big volcanicaly active areas. If you look on Rockies on the map, you can see granite + metamorphic in the west, remaining andesite + metamorphic in the east and between them lot of sediments. Large basalt areas are from LIPs. If subduction is still active under such mountain range, you get more andesite than in today Rockies. Also I wouldn't say that Andes are predominantly rhyolitic, there is roughly equal amount of andesite. You did it on map well, just that placement of Andes in template as granitic wasn't the best. After all, andesite is named after Andes.
With Laramide orogeny, the time after the orogeny has occurred has some degree of basin and range extension. The most accepted theory is due to the remaining gravitational potential energy from the laramide orogeny. I hope that next episode has faulting, it is quite important for orogeny, especially laramide and sevier. And you can do some funky stuff with transform faulting.
@@CAS13069 I would also like to see faulting. But I doubt that we will see that, because faults and uplift give you entire new mountain ranges and Edgar have map finished. It would change weather, wind, ocean current, bioms etc. But maybe will Edgar cover that big rift in Jannar? There also lots of faults, there will be some interesting rive/lake/volcanic systems.
YES ROCKS! I love how you added the explanation of why shallow seas are more prevalent at different times based on current tectonic events. Makes so much sense!
5:40 nope, it actually is called the Baltic Shield. There is a second name though, Fennoscandian Shield, it was introduced by Finnish geologist Wilhelm Ramsay (along with the term Fennoscandia). While the latter became widely accepted, the former, as far as I know, is used as the main one only in Finland, Sweden and Estonia, while the rest of the world prefers the traditional "Baltic Shield" (though in 1992 there was a CGMW recommendation to replace it with "Fennoscandian Shield" entirely. Edit: Well, yeah, it is a part of EEC, but I thought you were talking about the northern shield part of it. Also Baltica is the name of the proto-plate to which EEC belonged
hi! i am friends with a hydrogeologist who actually currently works for ireland's EPA, and we were talking through this problem a couple months ago as i was working on my own planet's geological formation. this is very similar to the method we worked out together, though i never did a timeline so i was working backwards from a map i'd already done and had some rough idea what the current tectonics looked like
Loving this! One thing I'll mention is that the shield/platform boundary doesn't seem to follow the boundary of the maximal extent of the ice sheets, but rather where ice sheets persisted for thousands if not tens of thousands of years, rather than the mere centuries or millennium or two of milder regions. So it doesn't have to be exact, and when in doubt, bias the platforms a little bit more poleward from that boundary line
I haven't even started this yet, but I want you to know the pure joy that hit me when I got the notification. I realized that tonight, I have something extraordinary waiting for me.
Yup, this is a huge part why Canada's population is so southern. The cold is a factor, for sure, but it's also because of the Canadian shield. In the Great Plains, like in Alberta, the population distribution spreads way more North than in Ontario or Québec for this reason.
This creates such a gorgeous map!! As much fun as it is to learn about worldbuilding from yours and Madeline’s content, it also makes me appreciate our real world so much more, like this is so crazy and amazing! I need to get back into gplates so I can get into this part eventually
Between Madeline's stream and the release of this video I've been continually imagining the suffering Edgar was putting himself through for this. I was beginning to worry about him; I'm glad he's got it done.
To answer the question of why there is more andesite in islands. The igneous scale runs from Rhyolite - Andesite - Basalt with each one being denser (among other things). Continental plates float on top of oceanic ones because they contain more lighter material (granite and other rhyolites) than the oceanic ones (consisting mostly of heavier basalts). Volcanic activity and plate collisions can roll and mix this material up. Pushing heavier Andesites upward. Oceanic island chains would then be more andesite and basalt than continental convergence zones.
i have been yearning for your newest video and coming home today to see this has made it much better! i always love to sit and watch your videos. you truly are a great teacher and are quite funny! can't wait to see more! this video has been one of the most interesting if yet and your creativity is definitely something to be admired! :)
I'm certainly no geologist, but I think the reason the sahara might have more sedimentary rocks is because it was once a massive wetlands, not because its a desert now. I could be wrong though, but food for thought.
Well, in this case, they ARE rocks. Rocks are a bunch of minerals together, basically. We didn't look at individual minerals (like quartz and stuff) here, so "rocks" is correct.
it's been a while (or more accurately probably i found this series late, watched all of it, and now waiting the full length for the first time for a video in this series). perfect timing too, as i was in the process of writing a summery of where you'd be able to find ores, fossil fuels (going of your an another persons old videos), and was trying to start looking into rocks. now in the future lets find out if the old metal videos still function.
hey even if you expect your cultures not to be interacting with the ocean floor, anyone who lives near shallow water is probably going to interact with the seafloor to some degree. then again idk how different coastal and just-off-coast minerals are going to be. food for thought?
Great video! One question, though: you previously talked about the huge lake on Esrie periodically flooding into the ocean. Wouldn't you expect the rocks to reflect that?
Great video, I just didn't understand the shield and platform bit, it seems counter-intuitive; I would have thought the terms should be swapped around.
Shouldn´t the remaining mountains in the old mountain-building zone be the typical rock of the zone or basement since there is no deposition on mountains, and the erosion would only leave the hardest rocks still standing, which aren´t usually sedimentary? Could be culturally important. Imagine a gigantic plain on top of an old zone with just a few small mountain chains standing the test of time. Since there are no newer ore-rich mountains close by, whoever controls these remnant mountains has a quasi-monopoly on the ores. Ore the caught be holy for being the only source of some ores for thousands of miles.
A strange reason why rocks are interesting to me in this context is because of DnD spell components. Some of the most common ones are diamond and ruby, of course with those as well as Sapphire and Emerald being the most common gems in our world. Problem is, they don't occur nearby, so a society can only commonly have them after a certain amount of globalisation. Otherwise they're too uncommon and too expensive
Hey, I've planned to start working on a gplates alternative made specifically for worldbuilding. I think the project could really benefit from the input of an experienced worldbuilder like you. So yeah, if you're interested in making sure that the worldbuilding community gets the best possible map making tool feel free to contact me ^_^
1st wow, the map looks awsome. 2nd would you consider a video on reverse tectonics? I have many worlds that i know how i want the land to look, parhapse some mountains as well but it is triky to reverse egineer the tectonics and how they looked, any advice?
QQ: Are you going to eventually consider impact structures? Impacts are a bit random, but they do tend to deposit rare elements (e.g., Iridium concentration at the KT boundary).
Kinda weird to call andean systems for granitic rocks when Andesite was named for the Andes, and the map sure looks purole dominated. I suppose the point is just more granite present than laramide type. I will also suggest the importance of metamorphics and ophiolites in ridge subduction zones.

i cheered aloud when you said cratons. this series is the good schist, as a geologist!
I have never been so hyped for a video titled "Rocks"
Whoa, this is something I would never have even considered as necessary, but can definitely see its usefulness. Very neat!

Rock type is important for were to place agriculture, as in you cannot grow stuff on shield rock, you need to find some pockets of sediments.

If Edgar disliked rocks before this video, he really dislikes them after it. That map is insane.
Hehe you watched Madeline's stream, I did too.
Between Madeline's stream and the release of this video I've been continually imagining the suffering Edgar was putting himself through for this. I was beginning to worry about him; I'm glad he's got it done.
Now THIS is the worldbuilding we all want!

yputube reccomended this to me and i am now going to binge the whole series because it's so chill and good vibes
I wish for Artifexian to have 10 million subscribers. *blows candles*
I've been checking the channel daily waiting for this. Awsome stuff, really made my Friday evening!
Can't wait for minerals, ore's, and gemstones
I'm certainly no geologist, but I think the reason the sahara might have more sedimentary rocks is because it was once a massive wetlands, not because its a desert now. I could be wrong though, but food for thought.
Damn! Looks like a Van Gogh painting.
Nice to see Artifexian's FAVORITE video to make no doubt ;)
"They aren't rocks, they're minerals" - Hank, probably.
Well, in this case, they ARE rocks. Rocks are a bunch of minerals together, basically. We didn't look at individual minerals (like quartz and stuff) here, so "rocks" is correct.
What they said^^. I learned this from a very extensive lecture from my old 9th grade teacher and I'll never forget that fact😅
@@Mercure250 I know, I know :)
Impressive work and dedication. Love it
It's always a fantastic day when there's a new Artifexian video!
can't watch right now, doing orbital physics for school. will be back later to watch but I am soooooooooooooo excited!!!!!!!!!!!!!!!!!

Babe wake up. New artefexian upload.
Yoo this video rocks! I was just starting with plotting the rocks of a worldbuilding project of mine
WE GETTING ROCKS WITHTHIS ONE
YAYYYY he’s back! :)
Loved it ad usual, Edgar! Are we also not getting fossil fuel deposits for the Planet? Ancient plant life as coal, etc, I think it would be neat!
Those are going to be in the upcoming ore deposits video
@AaronGeo thank you! 😁
incredible series !
YES! *ROCKS!*
Thank you for a fantasitc video on a topic that I find mostly irrelevant ;)
The map is pretty
Happy Holidays!
great vid as always
wakes up from a long dream* AH! Oh... Are we back? What did I miss?
He lives!
This Rocks
I'm stopping every single thing I'm doing to watch this video
YOU READY TO ROCK?!
The map at the end looks sooo pretty! Also I think the discord link is invalid.
mildly annoyed by the fact that andean orogenies aren't primarily andesite...
I have been trying to figure this out for my worldbuilding since I started.
hey even if you expect your cultures not to be interacting with the ocean floor, anyone who lives near shallow water is probably going to interact with the seafloor to some degree. then again idk how different coastal and just-off-coast minerals are going to be. food for thought?

What is the best type of rocks for agriculture? I feel like that would be important for world building.

Finally!! (In agonizing voice)
I thought we will never get here.
will you ever bring back your old artstyle in future videos? i miss it
Feels like all the cretons are in river valleys. Shouldnt they really be more upland areas, especially the platform parts?
is there a roadmap somewhere for what implementations/explorations are coming and in what rough order?
Rocks.
