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). A pyroclastic rock containing 25–75% volcanic bombs and/or volcanic blocks is called tuff breccia. Tuff composed of sandy volcanic material can be referred to as volcanic sandstone
