Speaking of big CAIs... Here is a rather nice 1cm plus CAI from a new CV3 I had classified. (still provisional at this time) http://i27.photobucket.com/albums/c165/jedisdiamond/NWA6717Mainmass.jpg
Here is the "CAI stone", which came from another group of NWA carbonaceous stones (not the same as above and still under classification). This one is on its way to Germany for research and study (may be the largest CAI ever!) but is still nice to look at. I am excited for the results of this one... http://i27.photobucket.com/albums/c165/jedisdiamond/DSCF5377.jpg http://i27.photobucket.com/albums/c165/jedisdiamond/DSCF5367.jpg I have CM, CO, CR and CV that all have CAIs visible.

Simple answer: any kind of chondrite. However, most common in carbonaceous chondrites, particularly CV's. They contain more refractory elements than the "ordinary" condrules they are found with. They were formed at higher temperatures and many show signs of repeated meltings. They are older than the next most early solar system materials, the chondrules, by 2,000,000 years or so. Two different dating methods give ages of 4567 my and 4571 my.for CAI's. Sterling K.
