Re: A 1.8 billion yr old Supercontinent, before Pangea proposed. (Mike Kremer)
Well it is a compelling theory, but seems to be a rather shakey one, in my slightly informed opinion.
It seems like a stretch to claim to be able to piece a continent pre-pangea together without many many examples. Seems like having the tell-tale reverse-magnetism signature isn't enough.
Of course, it is a fairly easy and safe gamble... If these few rocks have that signature, then it means there really could have been a continent before Pangea... So figuring out the configuration of it would be the real challenge. I don't know, I guess I'll keep watching this develope.
