Work performed in the CoMaX facility aims to better understand the history and emplacement of both terrestrial and extraterrestrial magmatic rocks, as well as the isotopic fractionations that occur during high-energy processes (evaporation/condensation, irradiation, ionisation…).

To meet the demands of this research, the experimental facility houses (1) High-Pressure–High-Temperature, (2) Atmospheric-Pressure–High-Temperature, and (3) Vacuum–High-Temperature equipment.

Due to this wide range of equipment, the CoMaX facility is divided into two complementary entities: “Experimental Cosmochemistry” and “Experimental Magmatology”.

The CoMaX facility is in the basement of the CRPG. At the local level, this facility is part of the ANATELo network (OSU OTELo); at the national level, it is part of the RéGEF (INSU), CRISTECH, Réseau des Electroniciens, Réseau de Technologie des Hautes Pressions, and RTVide networks.

The facility is accessible to all CRPG researchers and annually welcomes tens of users through internships, theses, or external collaborations. We also provide services for our academic collaborators or private partners; do not hesitate to contact us for more information.
