A deposit of a pyroclastic flow. Because of confusion in past use, the term is best restricted to deposits rich in pumice. Some of the largest single eruptive units known (>1,000 km3) are ignimbrites, associated with major explosive volcanic eruptions such as Santorini (1470 BC), Krakatau (AD 1883) and Mount St. Helens (AD 1980). Many ignimbrite deposits are preserved as extensive sheets of welded tuff.
