Doug >> Note that N. America has apparently been catching up with and "eating" the northern continuation of that ridge, though S. America is the faster moving continent.<< I agree But there are a couple of chunks off S. America also. These are very volcanic but the mass is not just conical like you would expect a volcanoes. They are mesa like indicating continent below. I see the small piece of continent splitting off and moving towards the big hole then the new basin solidified around it sealing the perimeter causing the magma to seek escape up the prefractured continent. I see the continent extending ten times deeper into the earth than the ocean basin. This crust is fractured deeply forming a pipe to direct lava to the top of the continental chunk. >> I will simply assume that plateau is a basaltic eruption from the mid-Cretaceous superplume episode or some such. << It is odd that it is huge and more or less flat at the top. If we have the lava again directed to the top of the section through cracks then the top areas could all get covered with lava and appear like they are only volcanic. Kamron
