The regional geology of France is commonly divided into the Paris Basin, the Armorican Massif, the Massif Central, the Aquitaine Basin, the Pyrenees, the Alps, the , the , the Massif des Vosges, the , the (Rhine graben) and Flanders Basin.[1]
Alpine orogen[]
The regions Alsace, Franche-Comté, Rhône-Alpes and Provence-Alpes-Côte d'Azur are part of the Western Alps.[2] Sediment from the Valais ocean crop out in the . The basement of the Briançonnais microcontinent crop out at Gran Paradiso, , , Vanoise and Ruitor. The Briançonnais cover sequences crop out in the . External massifs include the , Mont Blanc massif, and the . Sediments from the Piemont-Liguria Ocean crop out in and Ubaye.[3] The Jura mountains are part of the Helvetic nappes, that represent deposits from the European margin that were involved in the Alpine orogeny.[2]
Massif central[]
The geographic region of the Massif Central coincides with the geologic region with the same name. It is part of the Variscan orogenic cycle.[4] It was also a region of active volcanism during the Cenozoic.
