Coordinators: Anastassia BORISOVA and Sophie GOUY
Missions
The Petrology and Mineralogy department gathers a set of human power, analytical, and instrumental means aiming at supporting the characterization of rocks and minerals as well as other solid materials.
Scientific domains: archaeology, experimentation, magmatism, metamorphism, metallogeny, mineralogy, structural geology, paleontology, sedimentology, volcanology…
Services and platforms
Lithopreparation
