Abstract

Mineral chemistry of the magmatic biotites from the syn-mineral dacitic porphyry of Morro del Cobre (Frontal Cordillera of San Juan province) reveals that ther are Mg-biotites, typical of porphyry Cu precursor intrusives. Biotite geothermobarometry confirms the satured and oxidant character of the magma which evolved to shallower chambers.
