@Setanta,
Did I say near? hmm.
Jever steal a hunk a the causeway?
I did. Getting it on the plane was the hard part.I had it in my office ofr years until a student wanted to do a project on the ratios of Na/Ca/?Mg in diabases, gabbros and basalts of the world. He cut a thin section and "lost" the specimen from which it was cut.
Little bastard, shoulda flunked him./
