Dear List,
    The interesting thing about this is the reverse: that a Ford Fairlane engine block could conceivably be made from pallasitic meteoric iron, processed with the olivine phenocrysts removed. What a custom car that would be at the next classic car outing! Of course, if you have to ask how much, you can't afford it.

Let me simplify the formula a little bit:

1970's era Junkyard Ford Fairlane FE 390 Big Block + Olivine + Fraudsters + High School Metal Shop = Shirokovsky

Here is the big block link in case you want to get your hands on your own nickel-rich ataxite engine:

Sorry, couldn't help myself. I can't believe all of the talk over this garbage,

Adam

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
