Re: Tektite Question
Larry:
I have often wondered about this as well. I don't think that
one large asteroid could have caused all of the tektites but I do believe
that they form from impact events. For example micro tektites have
been found in sediments in Haiti just recently. These appear to correlate
with the Chicxulub impact crater at 65 Ma. Furthermore, the recently
discovered Alamo impact event, north of Las Vegas, has some odd looking
carbonate sphereules that may in fact be tektites. The appear
to have formed when a comet struck a seashore, more specifically a
carbonate reef or shelf, vaporized it, and sent it high into the atmosphere.
The "liquid" carbonate then rained down as globules and landed in soft
sediment. The are preserved QUITE well. Anyway, I am babbling....

With all the recent discussion of asteroids hitting

this question for the list.
Has there been any research done with the idea that Tektites were formed
when a large asteroid hit the earth? As there appears to be only
4 known
major sites with tektites.
New studies that I have read about indicate additional sites with
tektites with varying ages from 5 thousand to 65 million.
Because we have never seen the cause, are they the effect?
Can this be a logical assumption? Thanks for your attention.
