Abstract

This study takes an experimental approach to investigate the processes of tephra taphonomy. Tephra was applied to peats and movement monitored over periods of up to 6 years. Experiments combined field studies on six British peatlands with rainfall simulation experiments in the laboratory. The extent of tephra movement most likely depends on the density and porosity of the surface peat; there is no simple relationship with wetness. There is some indication that the extent of tephra movement depends on the tephra particle size but this will require further work to confirm. The taphonomy of tephra is an important issue which should be considered in all tephrochronology studies in peatlands
