Centre de Recherches Pétrographiques et Géochimiques
Cosmochemistry and planetology research themes at the  CRPG include
- evolution of the protosolar nebua as an ensemble of distinct chemical and isotope reservoirs
- participation in present day sample return missions (isotope microanayses)
- experimental cosmochemistry
- early evolution of planets: from core-mantle segregation up until the recording of the biological signatures of the Archean.
