Présentation
PhD student at the Institut de physique du globe de Paris, France. Studying the spatio-temporal dynamics of the magma reservoirs of Kizimen and Bezymianny volcanoes (in Kamchatka, Russia). Also part of a study on Dominica's magma plumbing system (Lesser Antilles).
Field trip done in Kamchatka in august 2019: 8 days collecting samples at Bezymianny and 6 at Kizimen, collaboration with russian, french and german researchers.
Performing analysis using SEM and EPMA on zoned crystals of orthopyroxenes and plagioclases and melt inclusions in orthopyroxene crystals, plagioclases, magnetites and amphiboles. The zoning patterns will help us decipher the magmatic processes that happened prior to the eruptions of these volcanoes, by using diffusion chronometry on orthopyroxenes and plagioclase and a Crystal System Analysis approach (CSA).
