History of France: The physical structure of France is dominated by a group of ancient mountains in the shape of a gigantic V, the sides of which form the two branches of Hercynian folding that took place between 345 and 225 million years ago. The eastern branch comprises the Ardennes, the Vosges, and the eastern part of the Massif Central, while the Hercynian massifs to the west comprise the western part of the Massif Central and the Massif Armoricain.These highlands are composed of resistant metamorphic, crystalline, and sedimentary rocks from the Paleozoic Era (about 540 to 250 million years ago), the last including coal deposits. They share the common characteristic of repeated planation, or flattening. Some variety is provided by subsequent deformation and faulting, such as in the ridge-and-valley areas of the Massif.
