Hal Provenmeir's book "Tektites a cosmic mystery" published 2013, is also a
good book and includes the study of the Texas and Georgia tektites.

First off, I have been down all week due to a PC crash last weekend and
finally back up and running again. I'm blaming the whole situation on my
comments about the "H word", must have been a bad omen. I'll keep my mouth
shut now and let those that are more intelligent than
Hi Paul,
Lots of hokum pokem around about this subject, but I do remember (a
serious) documentary some time back on UK television ('Horizon' I
think), they [horizon] where basically referring to sulphur type
spherules (the mythical Brimstone) deposits that where found around the
area. I believe b
Very clever Doug.
Glad the new week is upon us as it means more think
time as I head off to work each new day. Can't do the
calculus in the car sadly and we don't get traffic
jams up here so I can't do it while the engine
overheats, either but I'll dig out the appropriate
stuff and do some scratch

Actually, ignore that last bit about the wet craters. The Chesapeake was
dozens to hundreds of km offshore, and Bosumptwi may have been low-lying,
but Ries was high and dry at the time of impact. SE Asia is anyone's
guess.

Well,
if the moon has once been a part of the earth, do we have lunaites
at all? Are they in fact earthites? ;-

Zelmir,
To me the very fact that there are no known Earthites, (other than
Tektites) or any known 'venusites', (or indeed any meteorites of types
not believed to be from asteroids/persolar nebula/mars/moon/and maybe
mercury?) raises some interesting questions...

Some years ago, 2001, I found and purchased a very

Basically it's the formation of glass from heat and pressure. A
meteorite hits the earth, and the force melts the sand (silicate) to
sand. The same thing happens with atomic bombs.

Tom & all,
Tektites are now almost universally viewed as far-traveled impactites,
mainly terrestrial material "splashed" by meteorite impacts. Some
meteoritic components may be incorporated into the glass. Mysteries remain
as to why only a few impacts are known to have created tektites, and we'r

Dear Ian,
Meteorites - No
Wonderfully interesting, puzzling, frustrating pieces of glass YES.
There are both common and rare types. From inexpensive to How Much!!!
As far as your question, "valuable additions to a collection", you must
define for yourself what is valuable to you. To most of us
Tektites are melted earth rock. There is a very small number of people who believe
they are from the moon, but the vast majority of the scientific community believe that
is highly improbable. The biggest question is how you take rock, melt it into a clear
glass, and quench it fairly quic

Speaking of tektites here is a URL showing some teeny tiny lunar impact glasses with
interesting shapes. They were microprobed to determine whether they were impact or
volcanic glasses. Other similar samples are currently undergoing Ar-Ar dating
analysis. Enjoy the photos.
