| Abstract | Thermal manifestation associated to Planchón-Peteroa and Descabezado Grande-Quizapu-Cerro Azul volcanic complexes can be explained by a close relationship between a magmatohydrothermal systems and fault from the Malargue Fold Thrust and Belt. Two possible reservoir can be distinguish at different depths. The deeper one has temperatures near 350ºC and is controlled mainly by a mixture of volcanic and hydrothermal fluids. Instead the shallow one has a temperature range between 100-140ºC. |
