Resumen:
The San Pedro mining district is located in the central part of the San Rafael Massif (35º 21 58.6 S; 68º 23 22 W), province of Mendoza, Argentina. The San Rafael Massif is characterized by widespread volcanic and pyroclastic rocks of Gondwanan age, known as Choiyoi Magmatic Cycle. Two different suites can be distinguished within this volcanic sequence. The Lower Permian suite (lower section) has geochemical characteristics that indicate a subduction setting and a transpressional deformation style. The Upper Permian suite (upper section) has geochemical characteristics transitional between subduction and continental intraplate settings and a structural style typical of an extensional regime (Kleiman & Japas, 2009). New information provided by fieldwork and petrographic studies allow redefining the hydrothermal alteration assemblages and mapping the alteration zones.
