V33F:
Structure, Dynamics, and Properties of Silicate Melts and Magmas I


Session ID#: 8263

Session Description:
Physical and thermodynamic properties of silicate melts and magmas are key factors governing petrological and volcanic processes such as melt generation, transport, emplacement, crystallization, degassing and eruptive style. In order to better understand the dynamics of volcanic systems and to produce numerical models for the mitigation of volcanic risks, it is crucial to investigate the variation of physical and thermodynamic proprieties of silicate liquids and glasses as function of chemical composition and volatile content. The aim of this session is to describe the state of art of the physical and thermodynamic properties of silicate melts currently in our knowledge. For these reasons, we welcome contributions applying experimental, theoretical, numerical and innovative approaches for understanding the structure, dynamics and physical properties of magmas, silicate glasses and melts.
