This paper describes the methods used to collect volcanic gases from Vulcano, and to perform the chemical and isotopic analyses. The results indicate a fluctuation of the chemical composition of the gases within a short period of time. The origin of the vapor is inferred to be a mixture of sea water and the local meteoric water with subsequent vapor - rock interactions. The origin of CO/sub 2/ is ascribed to marine carbonates. A contribution of sedimentary materials is also suggested by the high N/sub 2//Ar ratio, and high delta/sup 15/N of N/sub 2/. On the other hand, most of the He is concluded to be of mantle origin.
