A discontinuous belt of Paleozoic mafic-ultramafic rocks outcrops along the WesternPrecordillera Argentina and Cordillera Frontal and constitute part of the Central Andeanbasement between La Rioja and Mendoza provinces, Argentina (Figure 1). This belt hasbeen interpreted for several authors as the limit between the Cuyania and Chileniaterranes accreted to the proto-Gondwana margin during Paleozoic times.
