An effective parameterization of texture-induced viscous anisotropy in orthotropic materials with application for modeling geodynamical flows
Autor: Javier Signorelli, Riad Hassani, Andréa Tommasi, Lucan Mameri
Publikováno v: Journal of Theoretical, Computational and Applied Mechanics (2021)
In this article, we describe the mathematical formulation and the numerical implementation of an effective parametrization of the viscous anisotropy of orthorhombic materials produced by crystallographic preferred orientations (CPO or texture), which

Textural and Compositional Changes in the Lithospheric Mantle Atop the Hawaiian Plume: Consequences for Seismic Properties
Autor: Andréa Tommasi, Lucan Mameri, Marguerite Godard
Publikováno v: Geochemistry, Geophysics, Geosystems, Vol 21, Iss 8, Pp n/a-n/a (2020)
Abstract We characterized the texture, composition, and seismic properties of the lithospheric mantle atop the Hawaiian plume by petrostructural analysis of 48 spinel peridotite xenoliths from four localities in three Hawaiian islands. Coarse‐porph

We propose that strain localization in plate interiors, such as linear belts of intraplate seismicity, may arise from spatial ariations in iscous anisotropy produced by preferred orientation of oliine crystals (CPO or texture) inherited from preious

Polymineralic inclusions in mantle chromitites from the Oman ophiolite indicate a highly magnesian parental melt
Autor: Tiffany L. Barry, Lucan Mameri, Hugh Rollinson
Publikováno v: Lithos. :381-391
Polymineralic inclusions interpreted as melt inclusions in chromite from the dunitic Moho Transition Zone in the Maqsad area of the Oman ophiolite have been analysed and compositions integrated using a rastering technique on the scanning electron mic

Predicting viscoplastic anisotropy in the upper mantle: a comparison between experiments and polycrystal plasticity models
Autor: Andréa Tommasi, Lucan Mameri, Javier Signorelli, Lars N. Hansen
Publikováno v: Physics of the Earth and Planetary Interiors
Physics of the Earth and Planetary Interiors, Elsevier, 2019, 286, pp.69-80. ⟨10.1016/j.pepi.2018.11.002⟩
International audience; Viscoplastic deformation of mantle rocks produces crystal preferred orientations (CPO or texture) of olivine and, by consequence, an anisotropic mechanical response for subsequent deformation events. Olivine polycrystals defor
