This study presents new stratigraphic, structural and hydrogeological data on the Tocomar geothermal volcanic area (Punaplateau, Central Andes, NW Argentina), together with preliminary geochemical and magnetotelluric data.The main geothermal reservoir is located within the fractured Pre-Palaeozoic?Ordovician units. The reservoir is recharged bymeteoric waters. Geothermal fluids upwell where main regional structures intersect secondary structures associated with thedevelopment of the Tocomar basin. Preliminary data indicate a reservoir temperature of ~ 200 °C and a local geothermal gradientof ~ 130°C/km associated with the Quaternary volcanic activity in the Tocomar area.
