Hello fellow cartographers,

I’ve been crafting this conworld over the past month or so, aiming for utmost accuracy with regards to plate tectonics; after I’ve successfully accomplished that phase, I'll be moving on to the next level—rendering mountains and other surface geological features. Before I move on to those other juicy details, however, I am hoping to get a critique from some of you accomplished and experienced fantasy cartographers (is Pixie still looking through this sub-forum?).

In particular, I’d like to know if my tectonics look plausible, especially some of my island chains. If you view the animation, you'll notice that the middle continent that spins counterclockwise somewhat "blocks" the development of the island chain to the west, at least until the last several million years. Figuring that the north has had more time to accumulate continental crust, I've slimmed down the souhtern part, which I reason formed later. Likewise, I've done the same to another island chain at around -90 longitude. Are these subduction zones plausible from a technical viewpoint? Is there anything I've overlooked? Please let me know.

By the way, the time frame from supercontinent-breakup-phase to "now" is 107.57 million years. Although Pangea officially broke up about 175 million years ago, I'm justifying my shorter time interval by positing that my conworld is somewhat younger than the Earth.

And lastly, the figures on the second tectonic map represent absolute plate motions in degrees per million years.

As always, this "atlas" style may not be everyone's forte, but I appreciate your viewing.
