Tuff - Wikipedia Particles of volcanic ash that are sufficiently hot will weld together after settling to the surface, producing a welded tuff Welding requires temperatures in excess of 600 °C (1,100 °F)
Tuff Rock | Properties, Formation, Uses - Geology Science Welded tuff is a pyroclastic rock that was sufficiently hot at the time of deposition to weld together If the rock contains scattered, pea-sized fragments or fiamme in it, it is generally called a welded lapilli-tuff
What is Tuff, Its Composition, Formation, and Uses? If deposited volcanic ash is hot enough, usually more than 600 °C (1,112 °F), it may sinter or fuse, forming a welded tuff Such welded rocks are common in rhyolitic volcanic ash deposits but can occur in other types
Tuff - an igneous rock of explosive volcanic eruptions. The rock formed from this hot ejecta is known as a "welded tuff" - because the ejected particles are welded together Some deposits might contain welded tuff near the vent and unwelded tuff at a distance where smaller, cooler particles fell to the ground

Lapillistone - ALEX STREKEISEN Most lapilli tuffs which remain in ancient terrains are formed by the accumulation and welding of semi-molten lapilli into what is known as a welded tuff The heat of the newly-deposited volcanic pile tends to cause the semi-molten material to flatten out as they become welded
