This actually answered a question I had wondered about - in the North West of Scotland there are mountains made of a distinct sandstone - Torridonian (named after the sea loch). I remember reading that the material that created this sandstone came from the erosion of mountains to the North West (where the Atlantic is now).
I looked up Scotland and 750 million years ago and there is a range of mountains to the North West. :-)
Incidentally, one of the cool things about the North West of Scotland is that the original landscape that was buried by the sandstone has been exposed in places.
Edit: I also seen to remember reading that the Brownstone buildings of New York are actually made from the same stone deposited on areas that ended up on the other side of the Atlantic when it split.
