WebThe solubility behavior of volatiles in silicate melts in equilibrium with complex fluids is of increasing interest because such mixed fluids are closer to natural ones. The ratio of S and Cl in magmas and volcanic gases is often used in volcanology and petrology to study magma degassing processes. The first experimental results on solubilities of S and Cl in …
