Evolution of carbonaceous chondrites (IMAGE)
Caption
Different groups of carbonaceous chondrites (here CO, CV, CM, TL, CI, and CR) can be traced back to different generations of planetesimals that formed over the course of about two million years. They differ in their proportions of fine-grained material (shown here in blue) and inclusions (shown here in brown).
