Carbonaceous Chondrite [CO3.7; S1; W0]
Fall, 3 January 1877

With an accompanying loud whistling sound, a large stone (~45 kg) struck a tree and broke into pieces. Unfortunately most of the material has since been lost. Warrenton is one of only 6 observed CO (Ornans-like) chondrites falls. Moreover, only two petrologic type CO3.7 meteorites (moderately metamorphosed) are known.

The CO chemical group of carbonaceous chondrites are defined by elemental and isotopic ratios and the COs are further distinguished by their small chondrules (usually Olivine-rich) and abundant refractory inclusions. Warrenton’s original complement of such inclusions has been altered. For example, original high temperature Hibonite and Perovskite were largely - if not entirely - replaced on some original homeworld. Nevertheless, Warren’s remaining 1.6 kg contains sufficient ancient refractory inclusions to continue as an occasional object of current scientific research.
