The archean is neat because it's somewhat typified by the banded iron formations that exist around the world. Its a global quasi organic geological phenomenon.
Idk about that visual model tho. Nothing I've seen has indicated that mantle plumes are caused by subducted plate sections interacting with the outer core transition layer. It also doesn't make much sense as we can track the Yellowstone Hotspot back out into the pacific ocean back 70-150 Mya. There's no subducting plate in the middle of the ocean to cause that Hotspot originally. Seems bunk on my layman understanding of PNW geology.
