This session aims to present and discuss results of natural and laboratory observations together with theoretical modeling to describe mass and energy transport processes in the crust and the mantle. Magma and fluid are the main transport agents. Mass and heat transfer governed by magma and fluid mass and energy transport are imaged globally and locally by geophysical observations such as seismic tomography and electrical conductivity profiles.
Characterization of magma and fluid sources and the plumbing systems facilitating their formation, evolution, and movement in the mantle and crust rely on accurate chemical and physical property data. Transport properties of magma and fluid are characterized primarily by their composition, temperature, and pressure, which, in turn regulate element partitioning between minerals, magma, and fluid. Fluid abundance and composition in fluid-bearing environments also affects partial melting and crystallization processes together with physical properties including equation-of-state and rheology of magmatic systems. Transport processes governed by these chemical and physical properties include magma and fluid formation at depth and their ascent toward the surface.
The session will focus on those phenomena. Relevant information includes physical and chemical properties and processes of magma and fluid, as well as geophysical imaging and geochemical mapping of the Earth's interior at scales from local to global. Presentations can include results of laboratory experiments, numerical modeling, and observations using geophysical and geochemical approaches. Contributions to any of these subjects are encouraged. Commission of Physics of Minerals of the International Mineralogical Association (CPM-IMA) supports this session.
