text: We have revisited the idea that surfaces of C, G, B, and F asteroids represent thermally metamorphosed material excavated from the interiors of these asteroids by comparing the ultraviolet, visible, near infrared, and 3-micrometer (µm) reflectance spectra of seven selected C, G, B, and F asteroids with spectra from 29 carbonaceous chondrites and artificially heated samples (Hiroi et al. 1996).
