Just a follow up to Bernd's post,

I've been reading a lot on CAI's lately so this discussion is great, keep
it going.
Have a look at:
Hsu, W., et al., 2000, High Time resolution by use of the 26Al chronometer
in the multistage formation of a CAI
Earth and Planetary Science Letters, 182, p.15-29.

They are indeed complicated little beasties.
