Summary

Abstract: Phreatomagmatic eruptions are common and dangerous worldwide. How large explosive event complexes evolve during eruptions, the processes that drive the evolution and what is in the rock record was studied in the Mawson Formation in Allan Hills, Victoria Land. The Mawson Formation is a unit of fragmented volcanic rock comprising debris from the Beacon Supergroup mixed with fragments from Ferrar ...
