Excellent explanation. I've been reading in this area and your video graphics and explanations were outstandingly helpful to solidify what I've learned. Thank you.
Great video! I live in the current taconic mountains on the Rensselaer Plateau which has the oldest rocks in NYS. The northern Taconic’s are still quite impressive! The highest summit being Equinox Mountain in Manchester Vermont at just under 4k feet in elevation.
Remember also that the Appalachians extend into The British Isles and Scandinavia as Northern Europe was also part of the story. The Northwest corner of Scotland is part of The Canadian Shield up to 3 billion years old. There are also sedimentray sandstones over a billion years old.
Great video. Really enjoyed the Appalachian orogenies as I am currently conducting a detrital zircon geochronology study in the Midcontinent and it is theorized that sediments came from the northern Appalachians via large transcontinental fluvial systems.

Hello sir! I am from India and here in its geological map on the Northern side Metamorphic rock is shown.. And as per your explanation there should be metamorphic rock
The red crystal at 8:01, I have found 4 different ones like that but 3 where white and one was like a brownish/red. I'm in the mountains of north carolina
I was watching a UA-cam video a few days ago that claimed that the Himalayan Range was a result of a near Earth object impact. A “grazing” of body against Earth and it left the telltale flattening impact that is the Himalayan Range.
At the time Pangea separated I’ve seen suggestions of a hot spot at the point of contact with North America, Africa and Europe. I was wondering if there’s any evidence of this within the Appalachian Mountain Range that you’re aware of?
Thanks for the question & for watching! Hot spot activity is often associated with continental break-ups. The break-up of Pangaea and the formation of the Atlantic ocean were likely driven by heat buildup beneath the converged mass of the super-continent, and the effects of some of that hot spot activity can be tracked through geologic time afterward. There's a good paper by Golonka and Bocharova (2000) that covers some of that geology.

The Appalachian Chain in Alabama linked up with the Ouachita -Marathon Mountain Range that snaked across Mississippi, Arkansas, Oklahoma and Texas. Those were created when the South American plate collided with the North American plate and separated along the line of that range. They believe that the NA plate traveled over the Bermuda Hot Spot which made the Ouachita Mountains rise in elevation in Arkansas and Mississippi. Those eroded away then dropped in elevation as it moved away from the hot spot to create the Mississippi Ebayment that was filled by water from the Gulf of Mexico. I think some believe the failed Reelfoot Rift (New Madrid fault system) was created when the hot spot moved away. There's another failed rift in SE Oklahoma that's below where a mountain range was attached to the Ouachita Mountains at a right angle.
Excellent! Great explanation, very high quality stuff. Thanks.
Impressive video. Clear and comprehensive. thanks
Really enjoyable video - a complex topic, explained clearly, is always more likely to be understood.
Great vid. Well done. Thanks. I just Subscribed. Looks like I have some catching up to do.
Nicely done! I didn’t know that the Appalachians are actually three separate ranges formed at different times.
A fantastic explanation. So interesting.
Straightforward, well explained. So much to learn. Thank you.

Excellent presentation, and so well explained. Very helpful. Thank you.
thanks for your vids. Really appreciate them
you actually make rocks interesting

Nice sigma clasts in the metamorphic rock example you showed.

I live on the Canadian part of the Northern Appalachians. Thanks for helping me understand how they formed.
OMG I love this, this helps so much! I thank you! ❤️

Fantastic, thank you
I guess eventually a new subduction break will appear going under southern India.
thank you!
thanks! i just realised volcanic arcs collide too

Interesting, well done video explanation. Imagine this happening over the course of tens or hundreds of years.😮

K2 is not in Pakistan infact it is located in Pakistan Occupied Kashmir.
