As far as I understand, carbonaceous condrites are not exactly rocky. They
are not stones made of something similar to granite or any other earthly
rock, if that is what you mean. Instead, carbonaceous asteroids are
primarily made of carbon (as the name says) and volatiles. I've never seen
one in person, but from the descriptions that I've got - it is said that
they are very dark and extremely fragile and crumby - I would say that they
probably vegetal coal rather than stones properly said...
