In my opinion, this memoir is essential reading for anyone serious about explosive eruptions, pyroclastic density cur rents and ignimbrites.
The first chapter defines the aims, gives an overview of relevant recent research and introduces central concepts relating to pyroclastic density cur rents.
Precisely what goes on in pyroclastic density cur rents to produce that diversity has been puzzling volcanologists for decades.
Pyroclastic cur rent direction was towards the viewer.
It forms the floor of many barrancos, possibly concealing a considerable underlying pyroclastic sequence.
These mantling relationships argue against an erosional origin for the bedforms by later pyroclastic flows.
On the western side of the edifice, two lava flows cover the pyroclastic flows and there is no palaeosol between them.
This lithofacies is thought to represent deposition from highly turbulent flow deposits with high rates of fallout resulting from pyroclastic flows entering a shallow sea.
