Hi Yinan
First you need to realize that the heavier the elements the less
abundant they are due to the stellar processes that form them. Once
you get to the heavies, everything is in ppm and there are no selective
element gold smelting operations that anyone has come up with in the

Iron meteorite classification: in the beginning...

It was :)
This is a good reason to pay respects to Harrison Brown, who was an

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
"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.

Dear List Members,
I have 54 auctions ending late this afternoon. I don't know what is going on
but the current bid prices are extremely low. Perhaps the international
visibility issue with eBay is preventing foreign bidders from seeing the items.
All were started at just 99 cents with no res
I have not seen visible gold in meteorites but I have seen them with copper in
them that is visible and more recently, something more exciting. More to come
on this soon.
Hope everyone is doing good!

Hello Doug, All,
We're looking at an iron meteorite, which is a piece of material in
which predominantly heavy elements have been sorted and accumulated
through processes that took place over billions of years. Saying that
gold is uncommon in the solar system doesn't mean much; we know that
differ
Hi All,
I'll have to back Doug on this one -- it is more likely that a transcription
error or font change might occur than that one iron meteorite should have an
anomalously high gold content by three orders of magnitude. I've seen
milligrams and micrograms often confused in technical papers, prob
Hi Jason
No, your example is so far from perfect, that you are comparing apples
as oranges.
but I do think you could find some data a little better somewhere to
fit your argument if you try hard enough.
Your Nickel and Iron example also is bad: 50% Nickel vs. a common 7%
nickel is a factor

Your colorful insight is, well, always worth-a-read and imminently
anticipated in all stories meteoritic...I urge you to write a book...I'd be
the first in line to have it. I'm serious!
