Different #meteorites, same birthplace: The parent bodies of
different groups of #CarbonaceousChondrites may have formed in the same region of the #SolarSystem…

Just outside Jupiter’s orbit, a ring-shaped region of high gas pressure formed. In this “dust trap,” over several million years planetesimals of varying compositions were able to form.
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).
