[WIP] Building a world from tectonics onward

[Charerg]

Looks good, though I'd drop the subduction zone extending westwards. This scenario would place the adjacent oceanic crust under slab pull in both directions, forcing a new ridge in the middle of that sea. That would also conflict with continent A shifting direction and breaking apart (as it would no longer be under slab pull in this scenario).

Doh! It's so obvious after you point it out...

Ok, so with the offending subduction zone removed, at 100 Mya I end up with the following scenario. Moving forward, since C has lost most of its northeastern slab pull forces, it changes direction to a more northerly vector. This, in turn, changes the nature of the C-B interaction from being simple convergent subduction to a retreating subduction zone. My current thought is to treat that as something of a Kermadec-Tonga situation where a piece of B--likely including a chunk of the continent in the south--gets ripped off and a new spreading center opens. That will evolve for a while, until I can think of what else to do with it.
