Distribution of temperatures calculated for the Villarrica springs and the laboratory batch experiments [TON tonalite experiment (180 days), AND andesite experiment (180 days)] using classical solute geothermometers (light grey) compared to temperature distributions derived from multicomponent geothermometry (dark grey). Classical solute geothermometer temperatures (SiO2, Na/K, Na/K/Ca, K/Mg, Li/Mg and Na/Li) were calculated using formulations of Arnórsson (1983), Can (2002), Diaz-Gonzalez et al. (2008), Fouillac and Michard (1981), Fournier (1977, 1979), Fournier and Potter (1982), Fournier and Truesdell (1973), Giggenbach (1988), Kharaka and Mariner (1989), Michard (1990), Nieva and Nieva (1987), Tonani (1980), and Verma and Santoyo (1997)
