PhD Research

Title:

“Understanding magma ascent and eruptive processes at Tongariro volcano through microanalytical investigations of the tephra record”

Research objectives

So as to assess volcanic hazards associated with explosive eruptions in a highly active zone as the Central Volcanic Plateau of New Zealand, the aim of the research will be to estimate timescales of syneruptive magma ascent based on tephra record from Tongariro volcano. Using high resolution analysis combined with experimental element diffusion rates, we will focus on submicron diffusion geospeedometry and crystal-melt boundary layers. Thus, we will be able to undersand storage history and quantitavely determine rates and timing of events before the onset of explosive volcanic eruptions.

Methods

  • Electron and ion microprobe analysis (Isotope Imaging Laboratory of the University of Hokkaido)
  • Quantitative image processing
  • Chemical element diffusion modelling of short length- and time-scales
  • Characterisation of submicron melt boundary layers around growing and dissolving crystals
  • CSD studies on orthopyroxene, plagioclase and clinopyroxene microlites
