Fluid Dynamics of Magma Reservoirs
For over a century, the chemical evolution of igneous rocks was explained by the concept of a large, liquid-rich magma chamber. However, geophysical surveys have been unable to identify these large chambers beneath active volcanoes. Furthermore, the thermal models and chemical data from these surveys, instead suggest that the magma spends most of its life as a liquid-poor ‘mush’ (a pile of crystals with liquid present in the pore spaces) and that the traditional idea of a magma chamber is, at most, a short-lived feature. Therefore, the aim of my project is to understand the fluid dynamics of these magma reservoirs and to answer questions which are fundamental to understand why and when magma is delivered to volcanoes.
