Description of the thesis topic

-This PhD is part of a major project recently funded by the National Research Agency (ANR). The ANR project is called MYGALE and aims at understanding the influence of hydrothermal alteration on volcano stability. The project will focus on La Soufrière de Guadeloupe, an active volcano in the Caribbean. More information about MYGALE are available here:
https//ites.unistra.fr/recherche/equipes/ge/ge-perso/anr-project-mygale.

This PhD will be in experimental volcanology, located in Orléans, France. There will be field missions to Guadeloupe to collect rocks for laboratory experiments, and also to participate in field work on the volcano. The laboratory experiments will aim at understanding the influence of hydrothermal alteration on the physico-chemical properties of volcanic rocks and at constraining the reaction kinetics. To do so, the candidate will mainly use the experimental facilities available at ISTO, Orléans (i.e., flow-through benches). The candidate will quantify alteration in-situ in the experimental device and post-mortem by 3D characterization using an X-ray microtomograph (porosity-permeability). The alteration products will be characterized using electron microprobe and/or X-ray diffraction.

Skills in volcanology and pressure-temperature experimentation will be assets for obtaining the PhD grant.

Work Context

The candidate will work at the Institut des Sciences de la Terre d'Orléans (ISTO) and will join the 'Magma' team. The candidate will also work with the MYGALE team, based at the Institut Terre et Environnement de Strasbourg (ITES), the Institut de Physique du Globe de Paris (IPGP) and the Volcanological and Seismological Observatory of Guadeloupe. (OVSG). The successful candidate will collaborate with another PhD student at ITES, who will study the physical and mechanical properties of weathered rocks.

Additional Information

The PhD can start from september 2022 to January 2023.
