During such episodes, Accepted 10 November 2011 voluminous ignimbrite deposits are produced which cover landscapes over 104–105 km2. In such sequences, Available online 30 November 2011 brief eruptive recurrence and chemical similarity limit the applicability of geochronological and geochemical correlation methods.
