The isolated exposures of the accretionary lapilli-bearing facies along the coastline may alternatively record shoreline or water interaction of pyroclastic flows.
Pyroclastic products are widespread and include lapilli tuff, lithic tuff, agglomerate and pyroclastic breccia; compositionally similar lava flows are massive or blocky.
The rhyolite has the form of a variably welded and massive, crystal-rich ignimbrite and associated non-welded pyroclastic deposits.
Nevertheless, the profusion of pyroclastic deposits signifies a major input to the volcanic-sedimentary record derived from subaerial volcanism.
Papers deal with a range of natural systems, including siliciclastic turbidity cur rents and debris flows, pyroclastic density cur rents and avalanches.
This memoir is set to become a benchmark publication in physical volcanology and the starting point for future research on pyroclastic density cur rents.
No pyroclastic lithic components were found in primary deposits.
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.
