Scientific paper

Laser-spot analysis was carried out on the Murchison, Murray, Nogoya, and Yamato (Y)-791198 CM chondrites in order to see microdistribution of noble gases. Primordial noble gases are rich in rims around chondrules in the four meteorites. This suggests that large fractions of the primordial noble-gas carrier phases in the CM chondrites might have accreted on chondrules prior to formation of the meteorite parent bodies. Solar-type noble gases in Murchison, Murray, and Nogoya reside preferentially in the clastic areas which were probably formed by cataclastic effects due to regolith gardening. Cosmogenic noble-gas concentration in the clastic areas of Murchison is enriched by factors of three than that in the non-clastic area, suggesting that materials consisting of the clastic areas have been exposed to cosmic ray on the surface of the meteorite parent body, or the clastic areas have high abundance of preirradiated grains.
