Deformation of upper mantle rocks with contrasting initial fabrics in axial extension
Walid Ben Ismail, Andréa Tommasi, Marco Antonio Lopez Sanchez +3
To explore the role of the olivine grain size and crystal preferred orientation (CPO) on the evolution of the microstructure and the mechanical behaviour of upper mantle rocks up t…

An effective parameterization of texture-induced viscous anisotropy in orthotropic materials with application for modeling geodynamical flows
Javier Signorelli, Riad Hassani, Andréa Tommasi +1
In this article, we describe the mathematical formulation and the numerical implementation of an effective parametrization of the viscous anisotropy of orthorhombic materials produ…

On the role of solute drag in reconciling laboratory and natural constraints on olivine grain growth kinetics
Jean Furstoss, Carole Petit, Andrea Tommasi +3
We investigate the effect of solute drag on grain growth (GG) kinetics in olivine-rich rocks through full field and mean field modelling. Considering a drag force exerted by impuri…
