Geofluid Systems of Koryaksky-Avachinsky Volcanoes (Kamchatka, Russia)
Table 2
(a) Water chemical compositions of deep wells of the Koryaksky-Avachinsky volcanogenic basin, according to sampling data collected from 1970–2014. Wells: GK1, G1, K6, R3, R2, 53, E1, KO1, K5, and K6 (well positions shown in Figure ). GK1, G1: data from G. Ryabinin (pers. com., 2011); R2, R3 (A. Evtukhov et al., 1995), and E1: Kopylova G. (pers. com., 2011). The remaining samples were collected by A. Kiryukhin and T. Rychkova, and analyses were performed in the Central Chemistry Lab of the Institute of Volcanology FEB RAS. and : hydrogeochemical geothermometers (, Fournier, 1977; and , White, 1970).
