Exchanges between the deep envelopes of our planet and the surface are largely associated with the formation and movement of magma or deep fluids. The movement of these liquid phases is closely related to the internal dynamics of the Earth (plate tectonics, convection, and growth and recycling of the crust), to its differentiation, and to the creation of heterogeneities. The programme "Magma and deep fluids" is intended to contribute to the understanding and quantification of the processes involved in these exchanges, focusing on three points : the processes of magmatic evolution and their kinetics ; the modes of magma transfer between the mantle and crust ; and finally the origin, distribution, and role of deep silicate and non-silicate fluids. The approach is multidisciplinary, closely combining experimental petrology, field observation, and elemental and isotopic geochemical measurements at different scales.


Deep fluids, evolved magmatic fluids, and non-silicate magmas
Magmatic accretion
Kinetics of magmatic processes





These studies are based on the development of innovative isotopic tools that rely on the CRPG analytical facilities (ion probes, noble gas mass spectrometers, TIMS, and next-generation ICP-MS), and on the CRPG experimental petrology lab.
