| Scope |
Melts and fluids are fundamental agents of mass and heat transport in the Earth's interior, governing its dynamics, including crust formation and evolution, volcanic and seismic activities, ore genesis, and volatile-mediated global material cycling. Their physicochemical properties, controlled by pressure, temperature, composition, and oxygen fugacity, directly influence partial melting, crystallization, element partitioning, isotope fractionation, rock and mineral rheology, seismic wave velocity, and electrical conductivity. An understanding of the behavior and roles of melts, aqueous fluids, and volatile-bearing minerals is essential for connecting surface to deep Earth processes, refining models of planetary evolution, and assessing implications for habitability.
This session aims to bring together scientists from diverse disciplines to discuss how melts, aqueous fluids, and volatile-bearing minerals influence properties and processes in the Earth and planetary interiors, from the crust to the deep mantle, across all spatial and temporal scales. We welcome contributions from novel laboratory experiments, geophysical observations, petrological and geochemical analyses, and computational simulations, and especially encourage interdisciplinary studies. Contributions from early-career researchers are particularly encouraged. We also welcome presentations from the communities of the Commission of Physics of Minerals of the International Mineralogical Association (CPM-IMA) and the Study of Earth Deep Interior (SEDI-J).
