Hi Pete and Michael: The latest information that I am aware of is by Rivkin, et al. in Icarus in 2006. Ceres is a G-class asteroid (similar to the C-class, carbonaceous, asteroids, but with some differences in its visible spectrum and a little brighter). Rivkin's analysis (of 3-micron observations) is that Ceres is composed of iron-rich clays and about 5% carbonates, which makes it similar to CI meteorites. However, there are other G-class asteroids, so the connection is not as clear cut as with Vesta and the vestoids (sounds like a rock group).
