See: http://www.geocities.com/american_meteorite_survey/stretch.html And in a long series of debates with the Late Darryl Futrell, I disputed his claim of Lunar orgin that such forms could have possibly survived if they had been formed on the moon, solidified in space to then, some time later, fall to the earth maintaining this form without any atmospheric ablation. Fanged buttons, and flanged dumbells are evidence that they solidified in space then fell to the earth... like meteorites. But it is the very rare stretch forms that eliminate lunar origin for the very reason that if they too came from the moon they would also have been ablated in the way the the flanged ones are. The Futrell-Schoner debates went on for quite a long time and as I remember I was almost "stoned" for being so adamant in my assertion of mega-Tunguska events as the producers of such objects. It is in the archives in 2001, and I think for those really interested in the tektite question it is worth reading those threads. All the evidence points to terrestrial impact rather than the moon even though no definite terrestrial craters have been found relating to their origin. Also tektites are problematic in so far as they are not what one would expect from material fused from earth deposits. I suspect cometary impactors that completely disrupted in the Earth's atmosphere, not reaching the ground to produce clearly defined craters like more solid objects would be apt to produce. I maintained in the debates with Mr Futrell that the explosion of the bolide was like a mega-Tunguska event that "blew away" the atmosphere to the ground and in the process fused ground material, as well as cometary solids to re-coalesce in the Earth's atmosphere to produce tekites such as are found. This position is also supporte in the distribution of the Indo-Chinites, and Australites, in that the "butter fly" pattern of distribution is similar to the tree flatenting observed at the much smaller Tunguska site. It is also interesting to note that the flanged buttons found in Australia, are thousands of miles away from the more common indo-Chinites, which they are related to, amd are not flanged. Also layered tektites are found closer to the source of the impact. These were not ejected very far whereas the Australites were ejected from the perimeter of the impact zone and thrown thousands of miles above and out atmosphere to fall, re-entering at hypersonic speed to produce the noted flanged button forms. And these prove that this form was produce at hyper-sonic speed as they re-entered the Earth's atmosphere. The rare stretch forms on the other hand are found only in regions much closer to the impact point, which is Thailand, Cambodia, and Viet Nam. The layered ones, which were not ejected are also found there. Thus is my "theory" as to their origin, and it is not just my "theory" but that of many others. (See Feb. 2001 issue of Meteorite Magazine that has a great article on the origin of tektites) (I hope that my answer does not evolve into another heated debate, with everyone wanting to stone me as I won't back down on my ideas regarding tektites. It was almost as bad as the "God, Lunar" topic that would not die... But I miss Darryl Futrell... He was a worthy opponent in the debates) Steve Schoner/ams --- Marcia Swanson <MJSOfArc_at_webtv.net> wrote: > To Tom and List, > I don't know Tom, but would like to know,what is the > number one theory > of where tektites came from? > Regards, Marcie <>< > > > ATTACHMENT part 2 message/rfc822 > From: "Tom aka James Knudson" > <knudson911_at_frontiernet.net> > To: "meteorite-list" > <meteorite-list_at_meteoritecentral.com> > Subject: [meteorite-list] Tektites? > Date: Thu, 17 Jul 2003 18:15:45 -0700 > > Hello Good List, What is the number one theory out > right now of where > Tektites came from? > Thanks, Tom > Peregrineflier <>< > The proudest member of the IMCA 6168 > > > > ______________________________________________ > Meteorite-list mailing list > Meteorite-list_at_meteoritecentral.com > http://www.pairlist.net/mailman/listinfo/meteorite-list > __________________________________ Do you Yahoo!?
