Hi all CAI lovers,
Looking at the jelly doughnut (chondrule-filled CAI), I wondered if the appearance could be misleading. I have seen some CAIs that are rather convoluted meaning in a 3-D view, they might form a cone or other shape where if cut along the right plane, it would appear as if the CAI was completely surrounding the chondrules, but in reality, the chondrule material is actually inside more of a CAI pipe or ice cream cone. Therefore in a cross-section, say through the top of an ice cream cone, it would appear that the cone material was completely encasing the ice cream, but in reality, it is not.
Just some thoughts when looking at a wonderful collection of CAIs from around the world. This is what makes this list fun!
Cheers,
Martin H

I have enjoyed every one of these as NWA 3118 is a favorite of mine but John's in particular begs the question:
If CAI's are the oldest things out there then how does chondritic material get completely encapsulated inside of one?
We have a lot to learn from this meteorite.

At the Tucson show, I picked up a nice NWA end
section with a wonderful CAI. I know, I know, its not an historic L6, but it
is pretty cool anyway.
When I do talks about the solar system, I like to
pass around a CAI for the obvious reasons. Now I can hold one up in front
of a class and everyone can see it.
Here are some pics of the piece:

Notice the smaller CAI island that drifted off the mainland, looking somewhat like Madagascar off the east coast of Africa.
Any thoughts on the CAI would be appreciated.
Happy viewing.
