The purpose of this session is to understand the structure, physicochemical and thermodynamic properties of silicate melts and glasses under extreme conditions and the implications to multiphase magmatic properties. In-situ studies of these types of geological materials at high temperatures and pressures are becoming increasingly routine and this session solicits submissions that involve any aspect of magmas or melts under extreme conditions. We strongly encourage the submission of contributions focusing on:
·melt/glass thermodynamics with emphasis on mixing properties,
·spectroscopic evidence for short and medium range structures,
·the role of cationic and anionic interactions on transport properties,
·volatile solubility and diffusivity,
·speciation behavior of elements, with emphasis on volatiles and trace elements,
·redox properties and the structural role of transition elements,
·the glass transition,
·rheological properties of magmas, with emphasis on both melt and multiphase systems showing complex rheology,
·experimental and computational determination of phase diagrams, particularly in volatile-bearing systems, and their impact for the study of magma properties.
·ab initio modeling of melt thermodynamics and structures and advances in analytical and spectroscopic techniques, especially in HP research.
Finally, applications to both natural magmas and glasses as well as to industrial processes will be most welcome.
