Recent advances in geochemical analysis, petrological investigations, experimental petrology, and computational modelling have significantly enhanced our ability to constrain the architecture of magmatic systems, assess timescales of magma evolution, quantify (isotope) fractionation processes, and investigate critical transitions from dormancy to eruption. However, challenges remain, including estimating magma storage depths, understanding crystal-melt relationships, integrating temporal and thermal constraints to better link physical and geochemical models, and calibrating models with experimental and natural observations.
A thorough understanding of magmatic plumbing systems is crucial to advance our knowledge of volcanic hazards, crustal evolution, and ore mineralisation. This session aims to investigate the multitude of key processes operating in magmatic systems, such as: magma generation, transport, mixing, and storage; mineral–melt–fluid reactions and fractionation; kinetic and equilibrium elemental and isotopic exchange. We invite contributions that rely on field observations, high-resolution geochemical data (major and trace elements as well as isotope ratios), thermodynamic and numerical modelling, geochronology and diffusion chronometry, machine learning, and experimental petrology to shed light on those processes and their timescales. Studies that combine various approaches (e.g. apply experimental or computational findings to case studies of natural systems) or develop new tools for understanding the complex evolution of magmatic systems are especially welcome.
