An ignimbrite is the deposit of a pyroclastic density current, or pyroclastic flow, which is a hot suspension of particles and gases flowing rapidly from a volcano. Ignimbrite is a pumice-dominated pyroclastic flow deposit formed from the cooling of pyroclastic material ejected from an explosive volcanic eruption. As the . Ignimbrites are pumice-dominated pyroclastic flow deposits with subordinate ash. There are many historic examples, most of which are restricted to valleys. Ignimbrite is a pyroclastic rock formed by very hot ground-hugging cloud of volcanic ash, blocks, and gases known as pyroclastic flow or pyroclastic density. Ignimbrites are composed of bomb- to lapilli-sized pumice fragments, and subordinate lithic fragments, embedded in a matrix of vitric, crystal, and lithic ash.
