"ground zero is auriferous, what would happen to the gold with regard
to the tektites?
Would the tektites contain any fraction of the gold? "

Hi Brian,

The tektites would likely have a higher concentration of gold, like in
the case of the Ivory Coast tektites where this actually happened.
Screwed the Ir analyses up because Au bearing material on Earth is also
high in Iridium.

But you are probably still talking about at most parts per million
anyway, so, nothing your going to be able to see with your eyes
assuming the tektites are by force well mixed, it will just be an
impurity in the glass. One would think that any clump of gold that
wasn't vaporized would not travel with the silicates anyway, as it is 7
times denser. So maybe a Muong Nong tektite would have some
inclusions. Too bad there aren't any from the source crater of Ivory
Coast tektites.

Kindest wishes
Doug

Greetings listees,

If tektites are produced as a portion of the ejecta from a large
terrestrial crater event and the stratum at ground zero is auriferous,
what would happen to the gold with regard to the tektites? Would the
tektites contain any fraction of the gold? In what form might one
expect to find it?

Happy hunting,
Brian
