My PhD thesis focuses
on the study of the chemical and mineralogical nature and the formation
mechanisms of volcanic aerosol particles. Such dispersions of solid, liquid or mixed solid/liquid
particles in the air are emitted at fumarolic or magmatic vents during
eruptions and affect, among others, the climate (ex. acidic sulfate particles
from Mt. Pinatubo in 1991), human health (ex. crystalline silica particles from
Soufriere Hills since 1995) and economy (ex. silicate particles from
Eyjafjallajökull in 2010).
The main interest of my work are PM10 secondary
particles directly forming from magmatic gases and emitted in the troposphere during
continuous quiescent degassing (ex. Vulcano) or persistent moderate explosive activity
(ex. Stromboli). They are characterized automatically and manually by single
particle analysis using CCSEM/EDX and manually using TEM. The resulting
particle types are then compared to mineralogies predicted to occur at the
observed field conditions by thermochemical modelling using HSC chemistry
(Outotec).
