Isotopic ratio and concentration of sulfur in the undersaturated alkaline magmas of Vulture Volcano (Italy)
Abstract
Both the δ34 value and the total S content of products from Vulture Volcano, Italy are mainly controlled by the separation of S gases, predominantly SO2, from high fO2magmas containing S predominantly as SO2-4. The addition of evaporites to such magmas appears to be a relatively uncommon and limited phenomenon. The total S content of the most primitive product of Vulture Volcano (5600 mg/kg) is very high. The high δ34S value of 4‰ indicates an origin through the partial melting of a mantle containing high S, enriched in 34S of unknown origin.
