Re: Permian extinction questions

Well, here in Canada away from the Canadian Shield,
prospectors look for diamond mines by finding out
where the thickness of Cretaceous volcanic ash is
greatest, because that's where the volcanic vents that
produced the ash would be, and that's where they drill
for diamond-bearing rock, and find it.
That show is not worth remembering.

Thanks! I'll try to find out the exact location. The researchers are
Luann Becker and a colleague.
