After using the topology-based method outlined in this Artefexian video (https://www.youtube.com/watch?v=CxFpWyAzWqw&t=1485s) to create my divergent boundaries, I’ve run into a problem.
At 900 MA, the Divergent boundaries all connect in the middle as they should.
But one timestep later at 850 MA, the Divergent boundaries form a sort of triangle, and I am not sure what this is. Is it a Pacific-type plate, or does this represent an error on my part? And if it does represent an error, how would I go about correcting this?
