Metallogenic evolution of the Sierras Pampeanas of Córdoba and south of Santiago del Estero: Famatinian, Gondwanic and Andean cycles

Five metallogenic stages are proposed for the metallogenic evolution of the Sierra Pampeaneas of Córdoba and south of Santiago del Estero, havin. having already been exposed the first two previous work. Metallogenic stage 3, corresponding to the second orogenic cycle of the Pampean-Famatinian compre...
