Abstract

The ignimbrite was deposited as a series of pyroclastic flows emanating from the caldera region of the Tindfjallajokull volcano and is associated with a ground-surge deposit. The main magma type was comenditic, and the phenocrysts reveal slight variations in physical conditions of the magma-chamber. The xenolith assemblage indicates a minimum depth of 3 km. The ignimbrite is composite, containing a suite of basic and intermediate glasses in addition to the comendite.
