Many ignimbrites are loose, unconsolidated deposits, but some exhibit welding, giving the ignimbrite the texture of a solid rock mass, hence the terms commonly used to describe these examples: welded tuff and welded ashflow. 1, record 1, English, - welded%20ashflow

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. [...] On pense que certaines coulées de cendres sont liées génétiquement à des plutons proches de la surface dont certains sont de grande taille et de nature complexe. 2, record 1, French, - coul%C3%A9e%20de%20cendres%20soud%C3%A9es
