Abstract

Oxygen isotopic composition of our solar system is believed to have resulted from mixing of two isotopically distinct nebular reservoirs, 16 O-rich and 17,18 O-rich relative to Earth. The nature and composition of the 17,18 O-rich reservoir are poorly constrained. We report an in situ discovery of a chemically and isotopically unique material distributed ubiquitously in fine-grained matrix of a primitive carbonaceous chondrite Acfer 094. This material formed by oxidation of Fe,Ni-metal and sulfides by water either in the solar nebula or on a planetesimal. Oxygen isotopic composition of this material indicates that the water was highly enriched in 17 O and 18 O (δ 17,18 O SMOW = +180‰ per mil), providing the first evidence for an extremely 17,18 O-rich reservoir in the early solar system.
