Tuff is a type of rock made of volcanic ash ejected from a vent during a volcanic eruption. Following ejection and deposition, the ash is lithified into a solid rock. Rock that contains greater than 75% ash is considered tuff, while rock containing 25% to 75% ash is described as tuffaceous (for example, tuffaceous sandstone).
Aug 15, 2023 · Tuff rock, also simply known as “tuff,” is a type of sedimentary rock that forms from the consolidation of volcanic ash and other volcanic debris. It is a unique rock type that results from explosive volcanic eruptions, during which a mixture of hot ash, rock fragments, and gases is expelled into the atmosphere.
The meaning of TUFF is a rock composed of the finer kinds of volcanic detritus usually fused together by heat.
Tuff, a relatively soft, porous rock that is usually formed by the compaction and cementation of volcanic ash or dust. (The Italian term tufa is sometimes restricted to the soft, porous, sedimentary rock formed by the chemical deposition of calcite, or calcium carbonate, or silica from water as.

Tuff (from Italian tufo) is a type of rock produced by the eruption of volcanoes. It consists of consolidated volcanic ash ejected from vents during a volcanic eruption. Rock with more than 50% tuff is called tuffaceous. The chemical and mineral composition of tuff varies according to what was in the molten magma.
