Département de l'Ardèche - 07

French department (formerly called "Vivarais") located south-east of the "Massif Central", along the Rhône valley.
It can be divided into 4 main areas:
- "Monts du Vivarais" to the north are composed of a metamorphic serie (granites, migmatites, gneisses, schists, amphibolites...) covered by phonolitic and basaltic flows in the Mezenc massif.
- "Plateau des Coirons" to the south-east is formed by Miocene basaltic flows overlying jurassic and cretaceous sediments
- "Cévennes" to the south-west are mountains composed of micaschists with many granitic intrusions.
- "Plateau des Gras" to the south is a large plateau formed by jurassic and cretaceous limestones. It is cut by the famous Ardèche canyon.
