James Kennett at Santa Barbara is back (again) with the Dryas impact theory 10900 BC. With him: Sweatman, Tankersley, and - in spirit - Loeb. Against them: the vulcanologists.
Sweatman is not a coauthor in the paper, but is credited; Tankersley gets more credit than he deserves. Loeb is quietly ignored.
Kennett ignores the Greenland crater, which has nothing to do with this, instead looking to Sweatman's Black Mat over the Assyrian jazira itself. This time they got shocked quartz.
Personally I am more on the side of the vulcanologists. Still: I must disassociate this blog from certain of their more Science-Be-Settled! claims, like this 2011 mess. I do want to point out that a volcano if powerful-enough might eject chunks of rock high enough that they come back to us as meteors so, why can we not kiss and make up.
Be interesting to see how the vulcanologists (and Colavito) respond. UPDATE 2/29/24 ... given Kennett's problems.
