Hi List,
Here are 3 pics of a genuine blue chondrule spotted upon breaking a
fagment of the CM2 meteorite Tanezrouft 082 (purchased last June in
Ensisheim, from A. Gouesslain/J.-L. Parodi, the meteorite finders).

Question: what could
Hibonite - Ca(Al,Ti,Mg)12O19 - in a CAI. It can be gorgeous.

Hello Jeff, Matthias, Ted, all,
Your wise suggestions about the blue inclusion are highly appreciated.
I also first thought of hibonite that was mentioned in a similar
discussion we had on the list a couple of years ago. At the time, Jeff
Kuyken showed us a chondrule-like inclusion in
CAIs can be quite round. The famous Blue Angel CAI was a fairly
round, mm-size object in another CM chondrite, Murchison (this
publication was in 1982-ish in GCA). Not all hibonite in meteoritic
CAIs is the same color. The blue comes from Ti3+, formed under reducing
conditions. The blue
inclusion. It
seems to be a solid blue CAI or chondrule.
Cheers,
Jeff
