Mass and energy transport processes in the crust and mantle are crucial to understanding the movement and distribution of materials and heat in the Earth's interior. These processes, driven primarily by magma and fluid, play key roles in Earth dynamics such as the formation and evolution of the crust and mantle, volcanic and seismic activity, and metamorphism. The mass and energy properties of magma and fluid, controlled by temperature, pressure, composition, and oxygen fugacity, affect many processes including partial melting, crystallization, element partitioning, isotopic fractionation as well as rheology of minerals/rocks, elastic wave velocity and electrical conductivity. A comprehensive understanding of the behavior and roles of magmas, fluids and volatile-bearing minerals under extreme conditions is fundamental to research in earth and planetary sciences.

This session will focus on exploring how transport properties govern those transport processes from local to global scales. Those properties include, but are not limited to, the physical and chemical properties of magmas, fluids, and minerals with volatiles, as well as imaging techniques such as seismic tomography and electrical conductivity profiles of the Earth's interior. We welcome contributions from laboratory experiments, numerical modeling, geophysical observations, and petrological and geochemical analyses, with interdisciplinary studies especially 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).
