Summary

It is proposed that the term pyrothalassite should be used to describe the materials that form the outer and upper covering of a volcanic edifice that rises from the sea bed, and it includes the fragmental materials produced by hydroexplosions and surf action in the upper layers of the sea. This material is both porous and enriched in thalassophile elements. These two characteristics give a pyrothalassite layer the ability to exert a profound influence on the magmatic evolution of volcanic islands that contain, or contained, such a layer.
