DESCRIPTION OF WORK:
This project aims to constrain the influence of decompression path on shallow magma dynamics (i.e. magma in conduit or dome). The decompression path, or the magma ascent history, is a key factor in the evolution of shallow magma; it influences the bubble nucleation and growth, the formation of permeable network, and ultimately magma fragmentation; hence the entire dynamics of an eruption.
This project combines insights gained from two sets of rapid decompression experiments: Firstly, using volatile-saturated analogue materials in a transparent set-up will allow for high-speed video analysis of bubble nucleation, growth and eventually sample fragmentation. Secondly, experiments on hydrated silicate melts and natural melts at magmatic temperatures will allow comparing experimental to natural pyroclasts as well as sample textures. A set of decompression paths, from simple linear to more complex scenarios, will be studied for both sets of experiments.
WORKING ENVIRONMENT:
The successful candidate will work for two years with Bettina Scheu and Ulrich Kueppers as well as other staff at the Fragmentation Lab within the group of Experimental Volcanology at the Ludwig-Maximilians-University Muenchen. The working group of Experimental Volcanology offers a stimulating, active working environment with scientists from Europe and worldwide, covering a broad range of topics including also physical volcanology and physics of melts and magmas. The associated labs host state-of-the-art experimental and analytical facilities. The candidate will also spend at least one month per year at another of the 13 institutions from 8 countries that form the NEMOH network. Likely secondments are to Bristol and Pisa, to gain additional breadth in experimental and numerical modelling techniques, respectively.
