The Chaîne des Puys volcanoes of the Auvergne, France

David Nowell New Barnet, Herts, UK The Chaîne des Puys is a series of remarkably fresh volcanic cones in the Auvergne region (Fig. 1), which covers a significant portion of the Massif Central, the large upland area in the southern half of central France, which at its greatest extent is about 360 km wide. Over a hundred assorted cones, domes and maars are mostly strung out along a north-south axis a few kilometres to the west of Clermont-Ferrand (Fig. 2), the administrative capital of the Auvergne and the Puy-de-Dôme department, which is named after the highest of these volcanoes (Fig. 3). The 96 Departments into which France was divided into after the French Revolution are named after geographical features, with two-thirds of them named after rivers. Thus the Puy-de-Dôme must not be confused with Le Puy-en-Velay, the ‘county town’ of the Haute-Loire which is the neighbouring department to the southeast, and also famed for being built around its slightly older Miocene volcanoes.
