Abstract

Types of layer 1 deposits in ignimbrite sequences include ground-surge, ground-layer, and jetted deposits. Ground-surge deposits are generally thought to represent deposition from turbulent, low-concentration pyroclastic density currents resulting from 'ash hurricane', initial stages of Plinian eruption column collapse, or blast-wave phenomena. Ground layers form by sedimentation from the fluidized head of a pyroclastic flow, and jetted deposits form by explosive jetting from the flow head as a result of heating of ingested air.-from Authors
