The study of the small bodies of our solar system provides information about its early history, more than 4.5 billion years ago. The study of larger, differentiated bodies (i.e., with a metallic core and a rocky mantle like Mars, the Moon and the Earth) provides information about their internal structure and their geologic history.

Our approach is based on the study of a variety of objects:

  • meteorites and micrometeorites (including their collection in the field)
  • returned samples from space missions
  • terrestrial impact craters and their ejectas (impact glasses in particular)


Ongoing projects

  • FAMES: Marie Sklodwoska-Curie project, funded by the European Union, about the fundamentals and applications of extraterrestrial magnetism (PI: Clara Maurel, 2021-2023)
  • ET-megafires: funded by ANR about the tropical megafires triggered by extraterrestrila impacts in the Quaternary (PI: P. Rochette, 2022-2025)
  • e-Diamant: Equipex+ project about the development of a Quantum Diamond Microscope at CEREGE with applications to the study of extraterrestrial rocks (PI for CEREGE: J. Gattacceca, 2022-2026)
