Rheology of Earth Materials :

Closing the gap between timescales in the laboratory and in the mantle


13 July 2020: Is the Earth’s transition zone deforming like the upper mantle?

In a paper just published in Earth and Planetary Science Letters, we combine numerical modeling of dislocation glide with published reults of diffusion experiments and revisit the rheology of wadsleyite, ringwoodite and majorite garnet under geological strain rates across the transition zone of the Earth’s mantle using theoretical plasticity models:
