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.
