Fluid-aided mass transfer and mineral re-equilibration are essential for metamorphism, significantly influencing the formation and evolution of the Earth’s crust and lithospheric mantle. Metasomatism interacts with igneous and tectonic processes, contributing to ore mineralization, alteration of oceanic lithosphere, and mass transport in subducted oceanic crust and the overlying mantle wedge. These processes have implications for fluid flow, volatile storage, and both regional and localized crustal metamorphism. The alteration of accessory minerals like zircon and monazite allows for dating metasomatic events and provides insights into the chemistry of involved fluids. Present-day fluid movement in the lithospheric mantle and deep to mid-crust can be studied using geophysical methods such as electrical resistivity and seismic data, further clarifying metasomatic processes inferred from petrographic, mineralogical, and geochemical data. This volume aims to unite a diverse group of geologists, each with expertise in various aspects of metasomatism, to contribute to a series of review chapters that outline our current understanding of how metasomatism influences the evolution and stability of the crust and lithospheric mantle.
