CO Group

The meteorites of this group are named for their type specimen Ornans that fell in France in 1868 - by that, not far from our home in the French department Doubs. There are only about 25 members of this group if we don't count all the probable pairings - especially from the Dar al Gani region, Libya, where many COs have been found. It's more than probable that all Dar al Gani COs arrived in one or two distinct falls.

All members of this group of carbonaceous chondrites belong to the petrologic type 3, and they show a certain relation to the CV group when it comes to chemistry and composition. Therefore, many researchers suppose that the CV and the CO group represent a distinct clan of carbonaceous chondrites that formed in the same region of the early solar system. However, the conditions under which the COs formed must have been different from the conditions under which the CVs formed because there are obvious differences.
