Hi Bob and list

The analyses:
Metallic powder, olivine etc...
Iron: 78% Nickel:18.25%
A general structure close to a pallasite

The metallic powder structure shows that sintering was used (frittage)
The powder was produced by atomization under gas.

It is a manufactured "stone".
So they decided to reproduce that "stone".
They got something close to the Shirokovsky but didn't go further
because of the money needed etc..

Their conclusion:
manufactured product, mainly with metallic powder and sintering process

All the best
Michael B.

Hi everyone,
I received this from a list member on Shirokovsky's origin. It's a
French paper from 2005. Would anyone care to translate some of the key
points?
Thanks,
Bob
