Detailed program (in progress)

  • Opening seminar given by Anny Cazenave
  • Seismic Structure of the Earth
    1. Introduction to seismology (Lekic)
    2. Inverse theory and Tomography (Lekic)
    3. Tomography Practical (Lekic)
    4. Body wave observations and deep Earth mysteries (Cottaar)
    5. Practical waveforms (SeismoDetectives) (Cottaar)
    6. Interpreting seismology in terms of mineral physics + BurnMan practical (Cottaar)
  • Mineralogy and Rock Physics
    1 – A quick introduction on the mineralogy & petrological processes in the lithosphere- asthenosphere system (phase changes, reactions, melting, reactive transport of melts). The lithosphere-asthenosphere boundary as seen in two natural examples; Ronda & Lherz.
    2 & 3– How do the lithosphere and asthenosphere deform? Long-term viscoplastic (ductile) deformation mechanisms: Dislocation creep, diffusion creep, grain boundary sliding. Deformation mechanisms & Rheology
    4 - Deformation and anisotropy of physical properties (seismic, thermal, and mechanical anisotropy)
    5 - Shear zones – strain localization
    6 – Melts and deformation (Tommasi)
  • Geodynamics
    Fundamentals of convection (scaling laws etc.), regional and global geodynamics, with a focus on dynamic topography, subduction dynamics, and seismic anisotropy (Becker)
    Interactions between Deep and Surface processes (Braun)
    Tectonics and plate driving forces (Jolivet)
  • Field excursion by Laurent Jolivet
  • Geochemistry
    1- The continental crust: How do we determine the composition of the continental crust? How did it form, evolve and recycle through Earth history? (Garcon)
    2- The mantle: How do we sample the mantle, what are the geochemical tools to investigate the mantle, what are the main processes that determine its compositional evolution, what is the current state of knowledge, and what are the major remaining questions (Stracke)
  • Geophysics
    1. A spherical planet. How do we know, why is it so, what is a planet ? [how do we measure, why the mountain are not too high, why is it spherical, a simple question a difficult answer : the Lichtenstein theorem, the Liapounov theorem, when a planet becomes spherical, the interior is spherical too] (Chambat)
    2. An elliptical planet. How do we calculate, what informations does it give ? [the order of magnitude, Clairaut equations, modern techniques for fast rotators, the observations, the induced informations, the inertia moments] (Chambat)
    Shape of the Earth, Rheology, Isostasy, GIA modeling (Spada)
