Tin extraction from granitic intrusions and transport in magmatic-hydrothermal fluids: implications for the formation of Sn(-W) deposits in

Sn is a rare metal with very high industrial demand. However, the magmatic-hydrothermal processes that affect Sn mobilization and transport in the deep
crust and their role in the formation of Sn(-W) crustal deposits are still poorly understood. This is due to the lack of constraints on the ability of volatile phases
to extract and transport Sn from deep to superjacent environments. This study is aimed at investigating the effect of fluid composition and redox state on the
partitioning of Sn between granitic magmas and volatiles, and its transport at deep crustal conditions (500 – 850 °C, 0.3-0.8 GPa). Experiments will be conducted
in a hydrothermal diamond anvil cell (HDAC) combined with SXRF and XAS analysis at BM23/ID24- DCM beamlines.
