The thickness of the lithosphere is a key parameter for tectonic processes at the axis of ridges. The expansion rate and magma flow of the ridge are two important parameters for controlling this thickness. In this presentation, we identify and test the effect of two additional parameters for the case of slow ridges: the depth of magma emplacement relative to the hydrothermal domain, and the temporal variability of magma flow. \u00a0<br \/>\nThe event will start with a coffee served in front of the Pasteur amphitheatre at 13:15.<br \/>\nThe presentation will be in French and will be available for streaming (http:\/\/streaming-a.osupytheas.fr\/embed\/live.html).<\/p>","protected":false},"excerpt":{"rendered":"<p>Nous recevrons **Mathilde Cannat**, directrice de recherche CNRS dans l\u2019\u00e9quipe de g\u00e9osciences marines de l\u2019Institut de Physique du Globe de Paris, m\u00e9daille d\u2019argent du CNRS 2009.
