Abstract.— “Calcite veins from Farallón Blanco, Sierra de La Ramada, Tucumán”. Farallón Blanco is placed in the eastern edge of Sierra de La Ramada, Burruyacú, Tucumán province. In the hill crop out metamorphytes (Precambrian – Eocambrian), granitoids (Paleozoic) and sedimentites of Cretaceous end terciary ages. Calcite lodes are emplaced in metamorphytes at both side of El Naranjito gulch. Main lode have 1,5 m wide and have been recognized 90 m along the strike. Metal mineralization, very scarce, is native gold, pirite and chalcopyrite disseminated in calcite and also in quartz veins. It is suggested that the deposit have and hydrothermal origin possibly related to the Complejo Alto de las Salinas.
