The cycling of volatile elements (e.g., C, N, halogens and noble gases) between Earth’s surface and its interior plays a crucial role in controlling the chemistry and mineralogy of the mantle with important implications for its rheology, redox state and melting processes.
In this scenario fluids and rocks from mid-ocean ridges, plume-driven continental magmatism and volcanic arc systems show distinct petrological, chemical, and isotopic compositions that clearly reflect mantle heterogeneities.
Natural fluid and minerals inclusions trapped in diamonds and minerals of either mantle rocks (peridotites and eclogites) and from erupted lavas provide a unique window to investigate the interaction between asthenospheric mantle and subducted slab, being this the main process that controls the geochemical and petrological variability of the deep Earth.
In this perspective, we are approaching an interesting new scientific era where the different disciplines can actively interact in a multidisciplinary context for investigating the mantle products (rocks and volatiles) improving our knowledge of the mantle heterogeneity and its link to the Earth formation and evolution.
This session welcomes contributions from various fields such as geochemistry (e.g., noble gases, stable isotopes), petrography along with spectroscopic investigations of natural inclusions, experimental petrology, thermodynamic and geodynamic modelling. Early-stage researchers are strongly encouraged to submit their contributions.
