Understanding the plutonic-volcanic connection in supervolcanoes
This project aims to develop a multidisciplinary research aimed to reconstruct a physico-chemical tomography of the plutonic-volcanic system in supervolcanoes. This sub-project concentrates on the study of the relation between silicic magma chambers and large collapse calderas and will study the characteristics of magma reservoirs that feed superuptions. Thought the study of eruption products of selected case studies (Permo-Carboniferous volcanism of the Catalan Pyrenees, Spain; Bolaños caldera, Mexico; Aguas Calientes caldera, Argentine)and the application of experimental and mathematical models, we will investigate the following fundamental aspects relative to the evolution of magma in silicic reservoirs: crystallisation, mixing, convection, and fragmentation, which we consider constitute usual parts of the full process in large-silicic caldera formation and evolution. In addition to the thermodynamic approach that we need to follow to characterise these processes we will also investigate the variation of magma rheology during each process and the mechanics of the host rock during magma chamber growth, rupture and subsequent eruption. The results obtained will give a more precise picture on the dynamics of large silicic magma chambers and associated calderas, and will contribute to the co-ordinated project by providing the analysis of the volcanic complex in the proposed reconstruction of a physico-chemical tomography of the plutonic-volcanic system in supervolcanoes
