Massif Central
The Massif Central (French pronunciation: [masif sɑ̃tʁal]) is a highland region in south-central France consisting of mountains and plateaus. It covers about 15% of mainland France.
Subject to volcanism that has subsided in the last 10,000 years, these central mountains are separated from the Alps by a deep north–south cleft created by the Rhône river and known in French as the sillon rhodanien (literally "Rhône furrow"). The region was a barrier to transport within France until the opening of the A75 motorway, which not only made north–south travel easier but also opened access to the massif itself.
The Massif Central is an old massif, formed during the Variscan orogeny, consisting mostly of granitic and metamorphic rocks. It was powerfully raised and made to look geologically younger in the eastern section by the uplift of the Alps during the Paleogene period and in the southern section by the uplift of the Pyrenees. The massif thus presents a strongly asymmetrical elevation profile with highlands in the south and in the east (Cévennes) dominating the valley of the Rhône and the plains of Languedoc and, by contrast, the less elevated region of Limousin in the northwest.
These tectonic movements created faults and may be at the origin of the volcanism in the massif (but the hypothesis is not yet proven). In fact, above the crystalline foundation, one can observe many volcanoes of many different types and ages: volcanic plateaus (Aubrac, Cézallier), stratovolcanoes (Mounts of Cantal, Monts Dore), and small, very recent monogenic volcanoes (Chaîne des Puys, Vivarais). The entire region contains a large concentration of around 450 extinct volcanoes. The Chaîne des Puys (near Clermont-Ferrand), a range running north to south and less than 160 km2 (60 sq mi) long, contains 115 of them (monogenic volcanoes only).[citation needed] The Auvergne Volcanoes regional natural park is in the massif. The amusement park of Vulcania near Clermont-Ferrand allows visitors to discover this natural heritage and introduces them to volcanology.
In the south, one remarkable region is made up of features called Causses in French and consists of raised limestone plateaus cut by very deep canyons. The most famous of them is the Gorges du Tarn (Tarn Canyon).
Mountain ranges, with notable individual mountains, are (roughly north to south):
The following departments are generally considered as part of the Massif Central: Allier, Ardèche, Aude, Aveyron, Cantal, Corrèze, Creuse, Gard, Haute-Garonne, Haute-Loire, Haute-Vienne, Hérault, Loire, Lot, Lozère, Puy-de-Dôme, Rhône, Saône-et-Loire, Tarn, and Tarn-et-Garonne; these form parts of the regions of Auvergne-Rhône-Alpes, Bourgogne-Franche-Comté, Nouvelle-Aquitaine and Occitania.
The largest cities in the region are Clermont-Ferrand, Limoges, and Saint-Étienne.
