The Borborema Strike-Slip Shear Zone System (NE Brazil): Large-Scale Intracontinental Strain Localization in a Heterogeneous Plate
Autor: Sergio P. Neves, Andréa Tommasi, Alain Vauchez, Thais Andressa Carrino
Publikováno v: Lithosphere, Vol 2021, Iss Special 6 (2021)
AbstractLarge-scale strike-slip faults are fundamental tectonic elements of the continental lithosphere. They constitute plate boundaries (continental transforms), separate terranes with contrasting geological histories within accretionary orogens, o

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

Bloodstream Infections Due to Wild-Type Pseudomonas aeruginosa: Carbapenems and Ceftazidime/Avibactam Prescription Rate and Impact on Outcomes
Autor: Carlo Pallotto, Andrea Tommasi, Elisabetta Svizzeretto, Giovanni Genga, Giulia Gamboni, Anna Gidari, Daniela Francisci
Publikováno v: Infectious Disease Reports, Vol 16, Iss 5, Pp 828-835 (2024)
Background. Pseudomonas aeruginosa is one of the major concerns among bacterial diseases even when it shows a wild-type susceptibility pattern. In 2020, EUCAST reconsidered antibiogram interpretation shifting “I” from “intermediate” to “sen

Dynamic recrystallization by subgrain rotation in olivine revealed by electron backscatter diffraction
Autor: Walid Ben Ismail, Andréa Tommasi, Fabrice Barou, Marco A. Lopez-Sanchez
Publikováno v: Tectonophysics
Tectonophysics, Elsevier, 2021, pp.228916. ⟨10.1016/j.tecto.2021.228916⟩
International audience; We document how dynamic recrystallization by subgrain rotation (SGR) develops in natural olivine-rich rocks deformed in extension to up to 50% bulk finite strain (1473 K, confining pressure of 300 MPa, and stresses between 115

Microstructure and seismic properties of amphibole-rich rocks from the deep crust in southern Tibet
Autor: Xiong Wang, Maoshan Yuan, Zhicheng Jing, Junfeng Zhang, Andréa Tommasi
Publikováno v: Tectonophysics
Tectonophysics, Elsevier, 2021, 811, pp.228869. ⟨10.1016/j.tecto.2021.228869⟩
International audience; The crust of southern Tibet shows strong azimuthal and radial seismic anisotropies. However, their origin has remained ambiguous. Here we characterized the composition, microstructure, and seismic properties of amphibole-rich

Deformation of upper mantle rocks with contrasting initial fabrics in axial extension
Autor: Marco A. Lopez-Sanchez, Walid Ben Ismail, Ernest H. Rutter, Sylvie Demouchy, Andréa Tommasi, Fabrice Barou
Publikováno v: Tectonophysics
Tectonophysics, Elsevier, 2021, pp.228997. ⟨10.1016/j.tecto.2021.228997⟩
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 to large strains, we performed axial extension experiments at 1200C, 30

Crust-mantle coupling during continental convergence and break-up: Constraints from peridotite xenoliths from the Borborema Province, northeast Brazil
Autor: Alain Vauchez, Maurizio Mazzucchelli, Shiran Liu, Andréa Tommasi

Tectonophysics, Elsevier, 2019, 766, pp.249-269. ⟨10.1016/j.tecto.2019.05.017⟩
International audience; We studied a suite of mantle xenoliths carried by Cenozoic volcanism in the Borborema Province, NE Brazil. These xenoliths sample a subcontinental lithospheric mantle affected by multiple continental convergence and rifting ev
