Low glass viscosity and rapid welding of ignimbrite would be principally favoured by high-temperature emplacement, alkaline magmatic composition and incomplete degassing. |
Explosively erupted pyroclastic material is called tephra and includes tuff, agglomerate and ignimbrite. |
Department of Energy terminal storage facility for spent nuclear reactor and other radioactive waste, is in tuff and ignimbrite in the Basin and Range Province in Nevada. |
This local marker unit conformably overlies an andesitic lapilli tuff and the Little Stand Tuff, a nodular rhyolitic ignimbrite. |
The ignimbrite and tuff rocks there form part of the Borrowdale Volcanic Group. |
These volcanics are a group that includes different volcanic materials such as Incesu ignimbrite and Seksenverentepe volcanite. |
