Cioni R., D'Amore F. A genetic model for the crater fumaroles of Vulcano island (Sicily, Italy). In: Geothermics, vol. 13 (4) pp. 375 - 384. Elsevier, 1984.
A description is given of a genetic geochemical model for the crater fumaroles on the island of Vulcano (Aeolian islands, Sicily). The chemical and thermodynamic characteristics of the fluid suggest that it derives from a mixing between a deep fluid of magmatic origin and a fluid from a shallow hydrothermal system. Variations in temperature and composition of the fluids sampled between 1977 and 1978 could be attributed to variations in the contributions from these two sources. The model suggests that the variations in S/C, S/Cl and CO2 ratios are the best indicators of variations in the magmatic component.
