Very interesting and compelling evidence. And this brings to my mind again, the thought of cometary air burst events as explanations for tektites. Those that were on this list 15 years or more ago must remember the numerous posts and exchanges I had with Darryl Futrell and others regarding mega air bursts causing these odd pieces of glass depleted of water.
After Shoemaker-Levy impacted Jupiter in July of 1994 Dr. Shoemaker, (a friend of mine) produced some papers on the event. What I found interesting was the odd puff of hydrogen and oxygen that the impacts produced. And that hydrogen was expelled into space, actually leaving Jupiter's gravity well, and the heavier oxygen was captured completely as the impacted Jovian atmosphere cooled leaving black smudges. So what I saw happening, that no one else could see, was that the areas of impact had vaporized solid cometary silicate components depleted of water which was dissociated of hydrogen by the impact, but oxygen rich. And as that impact area cooled the black smudges may actually be tektite glass. Re-condensed from the vapor cloud depleted of hydrogen, rich in oxygen, and silicate components. The black smudges are actually clouds of glass particles, completely depleted of water. I proposed this to Dr. Shoemaker in a rather lengthy explanation (much more so than here) in I think 1996 or early 1997, and he told me that that is a very interesting explanation for tektites. One that should be explored. Unfortunately to my and everyone's dismay--- Dr. Shoemaker was killed in a car accident in Australia shortly after... Mega air bursts do happen... And they create the things that are being seen now in this Dryas event. But with larger mega bursts, I think that such can and have produced the water depleted glasses that we know as tektites. And I think the evidence of the process was shown to us when Shoemaker-Levy struck the Jovian atmosphere in July of 1994. It would be interesting to see if there are any micro-tektites, (glass depleted of water) in any of the Dryas deposits.

It?s hard to stay objective in the YD impact debates, nearly impossible if you are one of the participants. And yet George has done a very good job of presenting current research from both sides of the aisle. But now he?s come down off the objective fence, and jumped into the fray with both feet. George, along with David Kimmel, Alan West, and James P. Kennett are headed to a meeting of American Quaternary Association, at the University of Wyoming, in Laramie, Wyoming, August 12-15, 2010. And they are going there to tell the world about a New Method to Produce Nanodiamonds from Research into the Younger Dryas Impact event. Heck, that?s only one of the posters from the event There?ll be many others. New paradigms are wondrous things.
