What are we studying ?

Our group uses the framework of Fluid Mechanics and Mechanics to study the dynamics of geological systems and planetary interiors. Our modeling combines theory, numerical simulations, and laboratory experiments. Regimes diagrams and scaling laws deduced from our analysis are then used to interpret the natural observations.


A- Thermal Convection in a solid-state mantle:


A1- Fundamental studies and Global Regimes:

  • Temperature-dependent viscosity

  • Interaction with compositional heterogeneities

  • Visco-Elasto-Plastic rheologies and the onset of Plate Tectonics


A2- Subduction


A3- Plumes and Hotspots


A4 - Small-scale convection



B- Mechanics of polycrystals and the generation of seismic anisotropy


C- Evolution of the Earth and the terrestrial planets


C1 - Magma Ocean Cooling in interaction with an atmosphere


C2 - Onset of Plate Tectonics and Continental Growth in the Earth


C3 - Present-day Venus

Participation to VERITAS project


D - Heat and Mass transfer out of hydrothermal systems

Velocity and heat flow measurements on the sea-floor


- Measuring temperature, velocity and concentration fields in the laboratory


- Movies, images, and cartoons
