The Chaîne des Puys (French: [ʃɛn de pɥi]) is a north-south oriented chain of cinder cones, lava domes, and maars in the Massif Central of France.[1] The chain is about 40 km (25 mi) long, and the identified volcanic features, which constitute a volcanic field,[2] include 48 cinder cones, eight lava domes, and 15 maars and explosion craters.[3] Its highest point is the lava dome of Puy de Dôme, located near the middle of the chain, which is 1,465 m (4,806 ft) high.[3] The name of the range comes from a French term, puy, which refers to a volcanic mountain with a rounded profile. A date of 4040 BCE is usually given for the last eruption of a Chaîne des Puys volcano.[4]

An outstanding example of plate tectonics in action and continental rifting, the Chaîne des Puys region became a UNESCO World Heritage Site in 2018.[5]

Formation

The Chaîne des Puys is located on the Limagne fault, a major part of the European Cenozoic Rift System which formed during the creation of the Alps roughly 35 million years ago.[5] The region has a wide variety of geologic features formed by the rifting. The mountain chain itself began to form approximately 95,000 years ago, and the volcanic activity that formed the range stopped about 10,000 years ago.[3] The majority of the cones were formed by Strombolian eruptions, and these cones usually have well-defined summit craters. Some have nested craters, and others show broken rims where lava poured through.[3]

In contrast, Puy de Dôme was created by a Peléan eruption; this type of eruption is characterized by long dormant periods periodically interrupted by sudden, extremely violent eruptions.[3]

Future eruptions at the Chaîne des Puys are possible and would result in the formation of new mountains.[6]

Research

Before 1750 and the chain's identification as volcanic, the Puys were rumored to be man-made mounds of mining waste or Roman forge furnaces.[7]

The chain was the subject of the pioneering research of English geologist George Julius Poulett Scrope, starting in the 1820s. In 1827 he published his Memoir on the Geology of Central France, including the Volcanic formations of Auvergne, the Velay and the Vivarais, which was later re-published in a revised and somewhat more popular form in The Geology and extinct Volcanos of Central France in 1858. These books were the first widely published descriptions of the Chaîne des Puys, and the analysis therein laid the foundation for many of the basic principles of volcanology.^{[citation needed]}

[de] Chaîne des Puys

Die Chaîne des Puys, manchmal auch Monts Dômes genannt, ist eine Kette von vulkanischen Bergen, im französischen Zentralmassiv, in der Region Auvergne-Rhône-Alpes. Sie erstreckt sich in Nord-Süd-Richtung über eine Länge von etwa 30 Kilometern und umfasst an die hundert erloschene Vulkane. Sie liegt westlich von Clermont-Ferrand, im Département Puy-de-Dôme. Die höchste Erhebung ist der gleichnamige Puy de Dôme, mit einer Höhe von 1465 Metern über dem Meeresspiegel.
