Autor: Tommaso Mandolini, Julien Chantel, Sébastien Merkel, Yann Le Godec, Nicolas Guignot, Andrew King, Jerome Hosdez, Laura Henry, Nadège Hilairet

Publikováno v: Journal of Synchrotron Radiation, Vol 30, Iss 5, Pp 962-977 (2023)

High-pressure (>1 GPa) torsion apparatus can be coupled with in situ X-ray tomography (XRT) to study microstructures in materials associated with large shear strains. Here, deformation experiments were carried out on multi-phase aggregates at ∼3–

Abstract Wadsleyite is the dominant mineral of the upper portion of the Earth's mantle transition zone (MTZ). As such, understanding plastic deformation of wadsleyite is relevant for the interpretation of observations of seismic signals from this reg

Kinetics and detectability of the bridgmanite to post-perovskite transformation in the Earth's D″ layer

Autor: Christopher Langrand, Denis Andrault, Stéphanie Durand, Zuzana Konôpková, Nadège Hilairet, Christine Thomas, Sébastien Merkel

Publikováno v: Nature Communications, Vol 10, Iss 1, Pp 1-9 (2019)

The D$${}^{{\prime\prime} }$$ ″ layer in the Earth’s lower mantle involves a seismic discontinuity which is often assigned to a mineral phase transition to post-perovskite, however, as this phase transition occurs over broad region the assignment

Dehydration-driven stress transfer triggers intermediate-depth earthquakes

Autor: Thomas P. Ferrand, Nadège Hilairet, Sarah Incel, Damien Deldicque, Loïc Labrousse, Julien Gasc, Joerg Renner, Yanbin Wang, Harry W. Green II, Alexandre Schubnel

Publikováno v: Nature Communications, Vol 8, Iss 1, Pp 1-11 (2017)

Intermediate-depth earthquakes (30-300 km) occur in subducting oceanic slabs, but their generation mechanism remains enigmatic. Here, the authors show through high-pressure and dehydration experiments of antigorite that dehydration-driven stress tran
