MADISON, “MultiphAse rocks Deformation In SubductiOn zoNes” is a research project financed by the Agence Nationale de la Recherche (2018 – 2022). The project leader is N. Hilairet, UMET, CNRS – Université de Lille.

MADISON is motivated by our lack of knowledge on the mechanical behavior of key rocks located in depths in regions where tectonic plate meet : the subduction zones. Their mechanical strength plays a major role on the mass transfers in depths, and on their shallow expressions seismicity and volcanism.

The physical properties of these rocks, for instance their viscosity and deformation mechanisms, will be studied by three complementary approaches: experiments, numerical models and natural samples observations.
