PhD thesis: Origin of Pleistocene lava-hyaloclastite sheets, southeast Iceland (on Hold)
Supervisors:James White, Magnus Gudmundsson

Aims
My study is based on a young lava-hyaloclastite sheet in southeast Iceland, and focuses on understanding subglacial eruption dynamics, the thermodynamics of magma-ice interactions, and the processes and timing of emplacement for the erupted material.
