MEMBRES DU CONSEIL
CONSEILLERS SCIENTIFIQUES (mandat 2020-2023)
Laura Airaghi is a university lecturer at the University of Orléans. She investigates the link between metamorphic reactions (including phyllosilicates) and deformation to better understand the mechanisms that control mineral replacement and the record of the P-T-t-d paths in the mid-upper continental crust. Recently, she explored the link between hydrothermal alteration in granites and strain localization and she started to set up analogue laboratory experiences of deformation in the Griggs apparatus.
Full professor at the Université Claude Bernard, Lyon 1. She is working on the various aspects of fluid-rock interactions in the lithosphere (mechanisms, nature, and kinetic of reactions) and their rheological and geochemical implications. Using a structural, petro-geochemical and mineralogical analysis she is more specialized in oceanic systems (ocean spreading ridges and faults). She combines field work, on land or at sea during oceanographic cruises, with hydrothermal experiments in the lab.
Hervé Cardon is a CNRS Engineer working at the laboratoire de géologie de Lyon. He is a specialist of high-pressure and high-temperature experiments combined with in-situ analysis. His work is focused on the investigation of fluid-mineral interactions from hydrothermal conditions to upper mantle conditions. The goal is to understand the possible consequences for life appearance and microbiological activity at the mineral surface.
Camille Cartier is a young assistant professor teaching at the University of Lorraine (France). Her research, conducted at the CRPG (Nancy, France), is focused on magmatic and cosmochemical processes that have led to the formation and evolution of planetary bodies (Earth, Moon, Mercury, asteroids…). Combining experimental petrology, geochemistry and thermodynamical modelling, she works on several topics, linked by a common thread: the impact of the “oxygen fugacity” parameter on phase equilibria and trace element partitioning.
Laura Creon received her PhD from Pierre and Marie Curie University and IFP Energies nouvelles in 2015. She is specialized in analytical coupling for igneous petro-geochemistry problematics. She has done her first post-doc at the Institut Néel (2015-2016) where she studied in-situ X-ray spectroscopy. She continued with a second post-doc at the Universidad Nacional Autonomous de Mexico, UNAM (2016-2017) where she coupled X-ray tomography with igneous geochemistry. Following these two post-doc she took Research and teaching positions at Le Mans (2017-2018) and Sorbonne University (2018-2019) where she worked on the halogens solubility in Earth mantle minerals. She took her actual position as France Manager of X-ray tomography activity at SEMATEC Métrologie in April 2019.
CONSEILLERS SCIENTIFIQUES (mandat 2018-2021)
Hélène Bureau is a CNRS Research Director at the Institut de Minéralogie de Physique des Matériaux et de Cosmochimie (Sorbonne University). Her work is dedicated to the fate of volatile elements (hydrogen, carbon, halogen, etc.) inside the Earth: cycles and transfers, storage and origin. For this purpose she uses high pressure and temperature experimentation combined with in situcharacterisations (synchrotron radiation), micro-analysis methods by ion beam, and the comparison of experimental results with the study of natural samples. Her main subjects deal with the growing conditions of diamonds in the earth mantle, and the storage of volatile elements in the transition zone.
CNRS Researcher at Montpellier Géosciences with ageologist background, she specialised in the study of minerals in the earth upper mantle mainly using experimental techniques of high pressures and high temperatures.She studied crystalline defects and their impact on the physico-chemical properties of ultrabasic rocks and their minerals as well as the consequences in geodynamics (process of ion diffusion, incorporation of atomic impurities and plastic deformation).
Benoît Dubacq is a CNRS researcher working at the Institut des Sciences de la Terre de Paris. He studies fluid-rock interactions in metamorphic rocks. His research uses thermodynamic modelling and crystal chemistry to better understand the history of rocks in the lithosphere via their pressure-temperature-time path. His recent work has focussed on the partitioning of trace elements between fluids and minerals.
Alexandre Mussi is a Lecturer in Physics at the Unité Matériaux Et Transformations (UMET) of Lille University. He uses Transmission Electron Microscopy (TEM) to study the plasticity of deformed minerals under mantle and subduction conditions. He mainly characterises dislocations by the weak beam technique (WBDF) and Large-Angle Convergent-Beam Electron Diffraction(LACBED), and has developed the transmission electron tomography to characterize their sliding/climbing planes. He currently uses MET orientation mapping associated with EBSD characterisation techniques to study highly deformed minerals. His research primarily focuses on silicates.
Benjamin Rondeau is a Lecturer at Nantes University. His research, conducted at the Laboratory of Planetology and Geodynamics, focuses on the properties of gems in general, and contributes to the establishment of criteria useful for gemmological expertise. His main activity focuses on the geology of gems, especially opal. This work now leads to the use of the opal as a marker of its formation conditions on Earth and Mars, in particular to reconstitute the paleoclimatic conditions on these planets.
