What “tuff” means
Wiktionary · Wikipediatuff/tʌf/
- nounA light porous rock, now especially a rock composed of compacted volcanic ash varying in size from fine sand to coarse gravel.
Tuff is a type of rock made of volcanic ash ejected from a vent during a volcanic eruption. Following ejection and deposition, the ash lithifies into solid rock. Rock that contains greater than 75% ash is considered tuff, while rock containing 25% to 75% ash is described as tuffaceous. A pyroclastic rock containing 25–75% volcanic bombs or volcanic blocks is called tuff breccia. Tuff composed of sandy volcanic material can be referred to as volcanic sandstone.
