[meteorite-list] Fukang Pallasite & Chinga Ungrouped?

[David Weir]

Hi Mike,

I read only recently that Fukang is a main group pallasite (don't 
remember the source but likely an LPSC abstract). I did also read the 
abstract on Chinga, Willow Grove, and Tishimingo. I don't own any of the 
above meteorites.

Regards,
David

Thanks for using my site.
