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.
