Hi List,

I have a Chinga Iron in my collection listed as IVB Anomalous.
According to this abstract, Chinga is Ungrouped. Is this the latest
consensus? If so I will need a different meteorite to represent the
IVB group in my collection.

Regarding the Fukang Pallasite, Arizona Skies states on their web
site that Fukang is Ungrouped. This is news to me. I searched the
internet and could find no info. Can any one confirm the official
classification of this pallasite? Of course, if it is ungrouped,
I'll have to add it to my collection as well!

55 unique planetary bodies represented in my collection and counting!

PS Of course, I went to David Weir's Meteorite Studies site first to
get his take on these two irons, but neither one is listed yet!
