Convection and transfers in a textured partially-molten planet from the magma ocean stage to present-day solid-state convection

How and when plate tectonics (PT) developed on Earth, and why the Earth is currently the only rocky planet of the solar system with PT, are two of the main enigmas of Earth and Planetary Sciences. The evolution of a planet is conditioned by heat transfer in its most viscous envelope, the mantle. This heat transfer is mostly due to convection, and strongly depends on the convective patterns, which in turn depends critically on mantle rheology. However, the link between rock rheology at small time- and length-scales, and mantle « effective » rheology at the long/large scales of mantle convection is still missing. I propose that it resides in the meso-scale structure of the mantle and…
