摘要: We discuss the possibility that CI and CM carbonaceous chondrites are fragments of extinct cometary nuclei. Theoretical observational work suggests comets evolve into asteroids, several nuclei now suspected to be among near Earth object population. This population is most likely source meteorites consequently, we may expect some from in this The mineralogy chemistry consistent with view they originate asteroidal objects spectral classes, these turn have a origin. do not suggest or directly delivered by active during perihelion passage come debris meteor streams. Instead, summarize arguments suggesting represent which evolved asteroids after losing their volatiles.
