Description
Individual of NWA 13167, a C2 ungrouped chondrite meteorite discovered in 2019. Only 5 pieces were discovered.
NWA 13167 has a black, highly porous matrix composed of phyllosilicates, carbonates, Fe-sulfides, and forsteritic olivine that contains FeNi-metal inclusions. Chondrules are small (~300 microm) compared to those in CV and CK chondrites, and CAIS are rare.
An oxygen isotope analysis was conducted at the University of New Mexico (K. Ziegler) and it was shown that NWA 13167 has an O-isotopic composition that is more 160-rich than that of CM chondrites and is distinct from both CV and CK chondrites. It has been proposed as a member of a possible new carbonaceous group, the CT chondrites.
Northwest Africa 13167 has experienced a low degree of terrestrial weathering and has features indicative of very weak shock (S2).
