A discontinuous belt of Paleozoic mafic-ultramafic rocks outcrops along the Western Precordillera Argentina and Cordillera Frontal and constitute part of the Central Andean basement between La Rioja and Mendoza provinces, Argentina (Figure 1). This belt has been interpreted for several authors as the limit between the Cuyania and Chilenia terranes accreted to the proto-Gondwana margin during Paleozoic times.
