In order to estimate a formation mechanism of isotopically anomalous material COS in the carbonaceous chondrite, melting and quenching experiments were performed varying chemical composition and cooling rate. Symplectitic texture consisting of magnetite and pyrrhotite in hundreds nm scales were reproduced in Ni-free system under rapid cooling condition. The present results suggest that COS also formed by simultaneous and rapid crystal growth.
