Topic:
The influence of crystal size distributions on dynamic processes in magmatic systems
Project outline:
Despite significant progress in understanding the rheological properties of silicate melts and two-phase mixtures (e.g., melt+crystals), it remains largely unclear in what way and to what extent the crystal size distribution (CSD) affects the rheology of a magma. The main aim of this project is to systematically investigate the effects of changing CSD’s on the flow properties of magma, and to use the newfound experimental scalings to model the rheological paths of magma during conduit flow and volcanic eruption. The work will consist of a combination of experiments on magma-analogue material and HP/HT petrological experiments on natural samples from two case study volcanoes.
The project is funded for 36 months by the Deutsche Forschungsgemeinschaft (DFG).
Requirements:
- background in volcanology, petrology, & physics
- interest in experimental & laboratory work
- skills in fluid mechanics and numerical analysis
Supervisors: Dr. Sebastian Mueller, Prof. Jonathan Castro (Univ. Mainz)
To apply, send one PDF including your CV, a research statement, and contact information for 2 referees to Sebastian Mueller (sebastian.mueller@xxxxxxxxxxxx). The research statement should include a description of undergraduate research projects/studies undertaken as well as future research interests.
