[meteorite-list] Shirokovsky

[Marc D. Fries]

Howdy,

I second the motion - a chunk of mantle boundary material, whether its
from Earth of not, deserves an explanation!  Here's a question - if it
came from the Moon would it also fall on the terrestrial fractionation
line?

Any chance its a fake?  Perhaps someone melted some Nantans and poured
them over a bunch of olivine or something like that.  I've never seen the
thing firsthand; does it have a Widmannstatten pattern?

Cheers,
MDF
