Laboratory modelling of magma emplacement in the Earth crust 1: testing the effects of magma viscosity

Volcanic plumbing systems set the stage for volcanic eruptions at the surface. The dynamics of magma emplacement in such systems remain poorly understood.

For example, magmas exhibit a huge range of viscosities (15 orders of magnitude!!), from fluid basalts to very viscous rhyolites, yet the effects of viscosity on magma emplacement in the crust have rarely been studied.

The aim of this project is to conduct quantitative laboratory models of magma emplacement, in which fluids of variable viscosities are injected.

The use of state-of-the-art structure-from-motion monitoring systems will allow a robust quantification of the results and a deep physical understanding of the modelled processes. This project builds on existing laboratory facilities at UiO and on NFR-funded projects, and the Master student will have the possibility to evolve in a large group of PhD students and postdocs.

The learning outcomes of the students are numerous: sub-volcanic systems, laboratory modelling, data analysis, physics, communication and team work.
