I have an opportunity to make an educational meteorite presentation to a
local metal detector club and a rock hound club. I do not want to reinvent the
wheel. Please send me or direct me to presentation resources.

Dear Steve, Norm and List Members,
I posed a question to D. Futrell some 10 years ago
concerning comet formation of tektites. I asked him
if it was possible that a comet could have entered
Earth`s atmosphere and left behind glass from melted
silicates from both the comet and Earth entrained dus

I'm open for a good answer, but if you just described
it, I didn't understand.
My theory on tektite formation:
Go back to the impacts of cometary material on Jupiter in July of 1994. I
think in this there is a clear demonstration of how tektites are formed. There
were huge plumes of plasma extending out into space, and large dark clouds of
re-condensed dust from the imp

Good Evening Everyone...
Might anyone be interested in purchasing a 125g part-slice of the Estherville
meso? It's a very fresh slice from the interior of a very large individual; no
oxidation whatsoever, and it has some large metal blebs. I can let it go for
six bucks a gram if anyone wants it
Hello everyone, I just wanted a little info on Dag 998 it is a CO3. I know
almost nothing about it and I picked up a small piece in Tucson. Thanks for

Norm,
That's a wonderful piece of data (and I can't
dare say "it's hard to swallow...").
Darwin had first described the Australites
in his account of the voyage of the Beagle in
1844, with a very nice illustration of a classic
flanged button. Darwin assumed they were
volcanic obsidian but c
Dear Norm, Steve, Sterling and List,
Thank you for your posts on tektites. The fact is
we know very little about the formation of tektites
and where the mystery crater(s), if any, are. I have
spent almost 20 years searching Thailand, Laos,
Cambodia and the Philippines. So far, the theories

Maybe those should be called "emuites" to convey their unique journey?

Sterling,
I too got drawn into tektites by the mystery. They
often tell their individual stories plainly, but we
still can't get the big picture out of them!
One comment on your comments though. Tektites
(australites) ARE very often emu gizzard stones. In
the dry lakes where they are most abun
Ill be giving a presentation on meteorites for a 4th grade class and want to
give each
student a small piece of meteorite. Nothing special - chipped fragments will
do.
Anybody got a couple of dozen I could pick up cheap? Maybe 20 grams or so each?
Thanks,
Gary
