Scheme of the proposed depth segmentation of the Copahue geothermal reservoir according to geophysical data (JICA 1992; Lazo et al. 2015; Lundgren et al. 2017), well data, fluid geochemistry composition and isotopic abundances (Chiodini et al. 2015; Roulleau et al. 2016), zeolite zone, mineral alteration assemblage (Mas et al. 1995, 1996), and pressure–temperature–depth profiles (JICA 1992)
