Before I read the following links, I'd like to express my unscientific
opinion about this subject.
I'm sure there are numerous causes for the separation of Pangaea into its
present configuration, that is, the present continental shapes.
As I became enthralled with the impact hypothesis surrounding the K/T
event. I mused that Pangaea had been impacted by a "string" of meteorites
actually "perforating" it in some places to trigger the break-up.
As a Northeasterner I mused that, the Baltic, Africa and NE NA, might
present such a "perforation" boundary.
As I said earlier, Volcanism and Plate Tectonics [presently I can't think of
any other causes] might be sufficient to trigger break-up. Today,
California and eastern Africa don't seem to need much else.
So, That being said, I'll eagerly return to read the links associated with
this post. Thanks for your patience.
