Geofluids play a critical role in the geochemical evolution of both mantle and crust. They produce different surficial manifestations such as volcanic plumes, fumaroles, and hot springs. Degassing activities from volcanoes and geothermal systems enables the exchange deep-sourced volatiles between Earth’s interior and atmosphere. Chemical and isotopic compositions of geofluids result from magmatic degassing to scrubbing-affected hydrothermal fluids, at which metamorphic devolatilization, radioactive decays, thermal biodegradation, meteoric and seawater infiltration, and microbial activity may contribute. Distinguishing among different fluid sources and defining the timescales of fluid production and migration are essential for volcano monitoring, exploration/exploitation of geothermal resources and quantification of global volatile cycles. Specifically, CO2 is an excellent indicator for tracing mantle (e.g., partial melting, metasomatism/refertilization) and deep/shallow magmatic processes in volcanic systems from different geodynamic settings. This session welcomes contributions concerning fluids from mantle to volcanic and geothermal environments using data from case studies, experimental and theoretical calculations, geochemical modeling, and integrated approaches. Studies using CO2 (in fluid and melt inclusions, fumaroles, volcanic plumes, rainwater, groundwater) to investigate volcanic plumbing system and surface gaseous emissions, as well as the deep mantle source and geodynamic fingerprint (e.g., CO2 in fluid and melt inclusions in ultramafic xenoliths) are also welcome.
