Volatiles in magmatic-volcanic systems

The abundance and flux of volatiles are important to the hazards associated with explosive volcanic eruptions. Volatiles in magmas can be determined from investigations of melt and fluid inclusions in combination with volatile solubility data. A comparison of the newly determined solubilities of H2O...

Zusammenfassung:	The abundance and flux of volatiles are important to the hazards associated with explosive volcanic eruptions. Volatiles in magmas can be determined from investigations of melt and fluid inclusions in combination with volatile solubility data. A comparison of the newly determined solubilities of H2O, SO2, and Cl in a molten Vesuvius phonolite with the compositions of Mt. Somma-Vesuvius melt and fluid inclusions further elucidates degassing and eruptive processes for this volcano.
