Nov 19, 2014 at 20:35 comment added David Hammen @Neo - That's exactly what Silver & Behn said in their paper, that plate tectonics is not a continuous process. It instead operates in fits and starts.
Nov 19, 2014 at 19:33 comment added Neo The implication that subduction stopping when super continents means an end to plate tectonics I think is a bit of a stretch. Certainly, you can imagine a unique world where the world is filled with transform boundaries and rifts, and actually growing in crustal for a small period of time (100-300myrs).
