Former hunting lodge of the , this villa of Capri has an amazing suite on the top floor that overlooks the entire Gulf. Possibly, the Pisciarelli waters are mixtures of evaporated local 4. Waters from Stufe Nerone and Terme Puteolane were analysed both in the present study and in Cortecci et al. Acidity in the Hotel Tennis waters is neutralized by reaction with rocks. Data points are compared with seawater sulfate d 34 S of q See text for deviating points on left.
Positions of Hotel Tennis and Pisciarelli samples are explained as due to mixing between shallow meteoric water and magmatic fluids rich in hydrogen sulfide. Large time variations in individual manifestations may be observed for Stufe Nerone and Terme Puteolane. On this subject, the thermal waters appear to be undersaturated with respect to anhydrite. Therefore, we may imagine three sources of sulfate in these thermal springs and wells: sulfate with d 34 S s q3. At Pisciarelli and perhaps at Hotel Tennis the magmatic contribution is persistent.
The water d 18 O is y4. The alternative is that the water is largely meteoric and that the dissolved sulfate is basically derived from the dissolution of anhydrite with d 34 S similar to that of seawater sulfate.

To the contrary, the waters from Hotel Tennis and, particularly, from Pisciarelli likely represent shallow meteoric water that is persistently heated by and enriched in magmatic water and sulfur.
Conclusions Sulfate minerals and native sulfur around fumaroles at Solfatara and hot water pools at Pisciarelli are ultimately derive from supergenic oxidation of H 2 S with a mean d 34 S s y0. Deviations from the mean value are mainly ascribed to competing isotopic effects during redox processes possibly mediated by thermophilic bacteria. The total sulfur in an unaltered trachyte specimen from Pisciarelli has a d 34 S s q1.

Waters from hot pools at Pisciarelli are chemically and isotopically distinct from those of thermal springs and wells elsewhere in the Campi Flegrei caldera. These features may be of interest for volcanic surveillance. Based on the NarClrTDS diagrams, waters from thermal springs and wells essentially appear to be mixtures, in different proportions, of diluted meteoric water and saline marine water. The marine end-member may be seawater from the bay of Pozzuoli which undergoes chemical and isotopic modifications due to both its interaction with host rocks and boiling processes at depth.
Interestingly, the origin of water and sulfate from the Hotel Tennis well seems to be very similar to that of Pisciarelli, i. In general, the influence of these gases on the sampled thermal waters from springs and wells is occasional, as at Terme Puteolane, depending on changes in the individual hydrologic circuits, coupled with a spatially heterogeneous flow of gases through the aquifer.
At Pisciarelli and perhaps Hotel Tennis the magmatic contribution is more persisting. Many thanks are due to Enrico Dinelli for his collaboration and assistance in drafting the manuscript.
