Geofluid Systems of Koryaksky-Avachinsky Volcanoes (Kamchatka, Russia)
Table 3
(a) Gas chemistry (vol%) and carbon isotopic data of deep wells of the Koryaksky-Avachinsky volcanogenic basin, according to sampling data collected from 1988 to 2013. Wells: GK1, K1, and R3 (well positions are shown in Figure 1). GK1, G1, data from G. Ryabinin (pers. com., 2011); the remaining samples were collected by A. Kiryukhin and T. Rychkova. Chemical analyses were performed in the Central Chemistry Lab (Guseva V. I.). Isotopic analyses (δ13C) were performed by B. G. Pokrovsky
