Rock formed when deposits of pyroclactic flows solidify.
The rock formed by the widespread deposition and consolidation of ash flows and nuees ardentes. The term was originally applied only to densely welded deposits but now includes non-welded deposits.
An igneous rock formed by the lithification of ash flow or pyroclastic flow deposits.
welded (ash hot enough to be welded together) and non-welded (air fall) tuffs from a nuee ardente.
the rock formed by the widespread deposition and consolidation of volcanic ash flows and nuee ardentes . The term includes welded tuff (recrystal-lized ash flows) and volcanic breccias.
A pumice-rich deposit formed by a pyroclastic flow.
a poorly-sorted pyroclastic rock body formed by deposition from a flow of pumice
tuff whose acidic lava fragments are welded by consolidation of ash flows.
A volcanic deposit formed by a pyroclastic flow. Ignimbrite layers can be soft and full of pumice such as the land surface around Taupo (from the Taupo eruption 1800 years ago); or hard rock where the deposit has been thick and hot enough for the particles to fuse together (eg at Bulli and Te Toki Points on Lake Taupo).
A type of rock which forms from hot pyroclastic ash clouds developed during explosive volcanic eruptions;
A rock created by the welding together of ash and other volcanic material.
Ignimbrite is a volcanic pyroclastic rock, often of dacitic or rhyolitic composition.
