Chemistry and microstructure of the isotopically anomalous material (COS) in the carbonaceous chondrite Acfer 094 are studied using synchrotron-radiation X-ray diffraction (SR-XRD) and transmission electron microscopy (TEM). SR-XRD and TEM observations shows that COS grain consists of magnetite+pyrrhotite (+minor pentlandite) with a symplectitic texture in tens nm scale. Such a nano-metered inter-growth texture may suggest the simultaneous and rapid crystal growth of the constituent minerals at the time of formation.
