L\u2019objectif de ces 9 jours de stage est de vous faire acqu\u00e9rir les techniques de base d\u2019analyse de terrain<\/strong> dans les 3 grands domaines de la p\u00e9trographie<\/strong> : magmatique, m\u00e9tamorphique et s\u00e9dimentaire, avec une approche dynamique<\/strong> de la formation des roches observ\u00e9es.\u00a0<\/p>

Dans le domaine s\u00e9dimentaire<\/strong>, l\u2019analyse de faci\u00e8s et le lev\u00e9 de coupes serviront de base \u00e0 l\u2019interpr\u00e9tation en environnements de d\u00e9p\u00f4t de syst\u00e8mes carbonat\u00e9s et silicoclastiques. Ce travail concernera les affleurements de Molinges, du Lac du Bourget et du Barrage de G\u00e9nissiat. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Dans le domaine magmatique<\/strong> (voir le terrain-virtuel correspondant<\/a>), les structures des corps magmatiques et les lithologies associ\u00e9es seront analys\u00e9es afin de reconstituer les m\u00e9canismes de mise en place des magmas et les dynamiques \u00e9ruptives, les processus de fusion mantellique ou crustale et les processus de diff\u00e9renciation des magmas.\u00a0<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Dans le domaine m\u00e9tamorphique<\/strong>, l’\u00e9tude des structures et des parag\u00e9n\u00e8ses des roches m\u00e9tamorphiques servira \u00e0 d\u00e9terminer les protolithes et \u00e0 reconstituer les conditions de d\u00e9formation et de recristallisation au cours de l’\u00e9dification d’une cha\u00eene de montagne. Ce travail s\u2019effectuera dans les C\u00e9vennes pr\u00e8s de Saint Jean du Gard (cha\u00eene hercynienne, Sud du Massif Central). <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
