PROTOPLANETARY DISK COMPONENTS CONTAINED IN PRISTINE CARBONACEOUS CHONDRITES

Carbonaceous chondrites (CCs) can beconsidered cosmic aggregates containingprotoplanetary disk components. Modern analytical techniques allow us to identify CCsunaffected by thermal or aqueous alterationprocesses, having a pristine nature. Such ahighly unequilibrated meteorites allow us toget clues on the early Solar System (ESS), astheir components are ancient materials retentive of chemical clues on their formation.The information they contain is valuable to beapplied to better understand protoplanetary disks.
