Olivine grains in the Allende CV3 carbonaceous chondrite matrix were examined mainly by TEM. Compositional data of olivine by EPMA are also given. It was revealed that void-like defects were observed occurring in iron enriched portions of both matrix olivine and rims of isolated olivine grains. Detailed observations of these void-like defects suggest that the void structure was formed during thermal metamorphism and that the thermal metamorphism was also related to some chemical reaction to form fayalitic olivine either in the pre-solar nebula or on a parent body.
