Volcanic Petrology Group

The Volcanic Petrology group conducts fundamental research on magmatic processes and rocks from active volcanoes. They use petrological techniques and integrate them with monitoring signals and numerical/analogue models to better understand and forecast volcanic eruptions.

Overview

The aim of the Volcanic Petrology group is to conduct fundamental research on magmatic processes and rocks from active volcanoes, toward better understanding and forecasting of volcanic eruptions.

Some of our underlying research questions include

triggering mechanisms of eruptions
storage conditions (P, T, fO2, fH2O, fS2, fCO2) of magmas prior to eruption
unraveling the processes that occur in the reservoir and volcanic conduit
time scales for all these processes
integration of topics #1-4 with monitoring signals (seismicity, deformation, gas chemistry) of active volcanoes
numerical modeling of magmatic, and volcanic processes, plus monitoring signals towards predictability of volcanic phenomena

The signature and strength that distinguishes this group from others worldwide is that we focus our research on deciphering the time scales for all of these processes.

Some of our research tools include:

Mineralogical and geochemical analyses, in-situ and bulk (techniques: electron microprobe, ion probe, FTIR, XRF, TEM, LA-ICP-MS: These mainly take place at EOS and NTU facilities: We also utilize facilities of our international collaborators.
High P and T experiments (phase equilibria and kinetics: in collaboration with colleagues from France and Germany)
Dating and geochronology (in collaboration with colleagues from France and USA )
Field mapping and stratigraphic studies of eruption sequences (other EOS Volcano group members and colleagues from PHIVOLCS and CVI)
Numerical modeling (FD, FEM; EOS and in collaboration with colleagues from Spain and USA)
