Les tufs pyroclastiques résultent de l'écoulement de fragments pyroclastiques, liquéfiés par l'eau ou par des gaz volcaniques, qui finissent souvent par constituer d'épaisses accumulations dans les vallées et les dépressions. Les matières pyroclastiques formées de cette façon peuvent être composées de «lave vive» solidifiée, de fragments de «lave inerte» issue d'éruptions antérieures, de fragments pyroclastiques également d'éruptions antérieures ou de fragments de roches arrachés aux parois du substrat lorsque les fluides volcaniques montent à la surface.  3, record 3, French, - tuf%20pyroclastique

Fiamme are lens-shaped, usually mm to cm in size, seen on surfaces of some volcaniclastic rocks. They can occur in welded pyroclastic fall deposits and in ignimbrites, which are the deposits of pumiceous pyroclastic density currents.  3, record 4, English, - fiamme

Record number: 4, Textual support number: 1 OBS

The pumice clasts, which are in a hot, plastic state when deposited from the pyroclastic flow, are compressed and flattened by the weight of the overlying ignimbrite body, producing elongated glassy clasts with ragged, flame-like ends... Many fiamme clasts continue to vesiculate after formation, leading to the development of spherical vesicles within them.  2, record 4, English, - fiamme

Record number: 5, Textual support number: 1 CONT

An ignimbrite is the deposit of a pyroclastic density current, or pyroclastic flow, a hot suspension of particles and gases that flows rapidly from a volcano, driven by a greater density than the surrounding atmosphere. Ignimbrites are often of dacitic or rhyolitic composition.  4, record 5, English, - ignimbrite

Record number: 5, Textual support number: 1 OBS

When coined by the New Zealand geologist P. Marshall in 1935, the term "ignimbrite" referred only to flows with emplacement temperatures high enough to cause the fragments forming the deposit to become adhered together or welded; this restriction no longer applies, and the term now includes any pyroclastic-flow deposit, welded or not.  3, record 5, English, - ignimbrite

If sufficiently hot when deposited, the particles in an ignimbrite may weld together, and the deposit is transformed into a "welded ignimbrite, "made of eutaxitic lapilli-tuff. When this happens, the pumice lapilli commonly flatten, and these appear on rock surfaces as dark lense-shapes, known as fiamme. Intensely welded ignimbrite may have glassy zones near the base and top, called lower and upper "vitrophyres, "but central parts are microcrystalline("lithoidal").  2, record 7, English, - welded%20ignimbrite

La coulée de cendres est l'élement de base de la plupart des dépôts pyroclastiques appelés tufs soudés, coulées de tufs, coulées de ponce, ou ignimbrites. [...] Les dépôts d'une coulée de cendres sont considérés comme analogues, mais pas nécessairement identiques aux dépôts produits par le passage d'une seule nuée ardente. [...] Les matériaux mis en place à basses températures, tels que les «coulées de ponce» de Crater Lake dans l'Oregon sont en grande partie non soudés dans les dépôts épais. Les tufs soudés à haute température du sud-est de l'Idaho sont densément soudés en couches très minces. La plupart des tufs soudés sont probablement mis en place à des températures intermédiaires entre ces extrêmes.
