The Joyango granite is located in the norwestern part of the Sierra de Ambato, in the province of Catamarca. U–Pb zircon SHRIMP determinations indicate crystallization ages of 323.8 ± 2.2 Ma. The chemical composition of the Joyango granite (Rb-Ba-Sr content and Zr/Hf relation) indicates that it is an evolved granite of crustal derivation that displays a high degree of differentiation. The Ga and Al contents and their relationship with the Ce, Nb, Zr and Y contents, allow the Joyango granite to be interpreted as type A. Geochemical characteristics and similar ages have been identified in other areas of the Eastern Sierras Pampeanas, particularly in the San Blas, El Durazno and Huaco (Sierra de Velasco), La Quebrada (Sierra de Mazán), El Salto and Ayacucho (Sierra de Fiambalá) and Cerro Colorado (Cerro Negro) granites. This highlights the importance that the carboniferous magmatism has in this area of the Sierras Pampeanas.
