En classe de Terminale S, \u00ab\u00a0La convergence lithosph\u00e9rique\u00a0\u00bb, apr\u00e8s avoir \u00e9tudi\u00e9 les caract\u00e9ristiques du magmatisme des zones de subduction, on recherche la cause possible \u00e0 l’hydratation des p\u00e9ridotites du manteau au dessus du plan de B\u00e9nioff.
\nLes compositions min\u00e9ralogiques des roches de la cro\u00fbte oc\u00e9anique en subduction ont \u00e9t\u00e9 \u00e9tudi\u00e9es, au microscope polarisant ou sur \u00e9chantillon macroscopique.
\nL’objectif de cette activit\u00e9 est de rechercher la pr\u00e9sence \u00e9ventuelle d’eau dans des m\u00e9tagabbros de composition min\u00e9ralogique connue.<\/p>\n
