Scientist

Marguerite Godard is Director of Research at Géosciences Montpellier. She began her scientific career working on processes of magma flow and transport in partially molten mantle from mid-ocean ridges to subduction zones by combining petro-structure, geochemistry (LA-(HR-)ICP-MS…) and numerical modeling. She recently added to her research topics the study of hydrothermal alteration in the sub-seafloor, with application for CO2 sequestration and H2 production. For these studies, she participated to the development of new experimental devices (ICARE Lab) to monitor the hydrodynamic and chemical changes induced by fluid flow (T up to 400°C; P ~ 40 MPa; variable pCO2) in (ultra-)mafic rocks.

Lab

Géosciences Montpellier is a Joint Research Unit CNRS-Montpellier 2 University (110 scientists/engineers and 50 postdoc/PhDs) which has a broad expertise in Earth sciences, from mantle geodynamics, petrostructure and geochemistry to hydrogeology. It is involved in several fundamental research programs (IODP, ICDP, French National Research Agency) and collaborative projects involving industry (ADEME, EU-FP7 …). CNRS nurtures VOXAYA, a high technology R&D company specialized in 3D imaging.

Géosciences Montpellier has full access to high performance analytical (clean labs, SEM, EBSD, EPMA, (LA)HR-ICPMS & ICPMS, Raman, Mossbauer) and computer facilities. It hosts the ICARE percolation-reaction laboratory. It benefits from Montpellier University’s teaching facilities and integration/housing programs.
