'''Puy''' is a [[geology|geological]] term used locally in the [[Auvergne (région)|Auvergne]], [[France]] for a [[volcano|volcanic]] [[hill]]. The word derives from the [[Provencal]] ''puech'', meaning an isolated hill, coming from Latin ''podium'', which has given also ''puig'' in Catalan and ''poggio'' in Italian.
Most of the puys of central France are small [[cinder cone]]s, with or without associated [[lava]], whilst others are domes of [[trachyte|trachytic]] rock, like the domite of the [[Puy-de-Dôme (mountain)|Puy-de-Dôme]]. The puys may be scattered as isolated hills, or, as is more usual, clustered together, sometimes in lines. The chain of puys in central France probably became extinct in late prehistoric time.
Other volcanic hills more or less like those of Auvergne are also known to geologists as puys; examples may be found in the [[Eifel]] and in the small cones on the [[Bay of Naples]], whilst the relics of puys denuded by erosion are numerous in the [[Swabian Alps]] of [[Württemberg]], as pointed out by [[W. Branco]]. Sir [[A. Geikie]] has shown that the puy type of eruption was common in the British area in [[Carboniferous]] and [[Permian]] times, as abundantly attested in central [[Scotland]] by remains of the old volcanoes, now generally reduced by [[denudation]] to the mere neck, or volcanic vent, filled with [[tuff]] and [[agglomerate]], or plugged with lava.
See Sir A. Geikie, ''Ancient Volcanoes of Great Britain'' (1897).
