(a) Sr and Nd isotopic ratios of Campi Flegrei and Somma-Vesuvius volcanic rocks. Isotope data from Piochi et al.53. (b) Cl versus CaO and Na2O contents of matrix glasses (this study) and melt inclusions in mineral phases (data from34,35,36,37). Somma-Vesuvius data are from Pappalardo and Mastrolorenzo3. Horizontal lines denote saturation pressure for different water and Cl contents (solubility models by38).
