This study presents new stratigraphic, structuraland hydrogeological data on the Tocomar geothermal volcanic area (Puna plateau, Central Andes, NW Argentina), together with preliminay geochemical and magnetotellurica data. The main geothermal reservoir is located within the fractured pre-Paleozoic-Ordovician unit. The reservoir is recharged by meteoric waters. Geothermal fluids upwell where main regional structures intersect secondary structures associated with the development of the Tocomar basin. Preliminary data indicate a reservoir tmperature of 200°C and a local geothermal gradient of 130°C/Km associated with the Quaternary volcanic activity in the Tocomar area.
