Abstract-I review the dynamical and compositional evidence for possibly
linking CM chondrites and asteroids having G-class taxonomic
designations. Three G asteroids have been identified through previous
theoretical studies as being likely meteorite source bodies due to their
locations near resonances. Two of these objects, 19 Fortuna and 13
Egeria, have spectral properties that are consistent with such a linkage
with CM chondrites. Fortuna has a similar strength 0.7 Ám absorption
feature and near-infrared spectral slope to CM chondrites, but a weaker
ultraviolet feature. Egeria also has the characteristic 0.7 Ám feature
of CM chondrite spectra, but does not match as well in the
near-infrared. However, since the 0.7 Ám feature is apparent in the
spectra of approximately one-half of measured C-type asteroids, no
definitive statement about any linkage can be made. Ceres is spectrally
different from known meteorites in the 3 Ám wavelength region and cannot
be convincingly linked with any meteorite group.
