Book 2016is tholeiitic and belongs to the Parana Magmatic Province (PMP), which extends throughout South America. In contrast, the volcanism in Córdoba is geographically restricted and of alkaline nature, representing a potassic locality peripheral to the PMP. To understand the causes of and geodynamic proce

Other localities where volcanism is exposed are Sierra de las Quijadas and Cerrillada de las Cabras of San Luis Province. In SCC, as in the other mentioned localities, a volcanic–sedim

Introduction,e subsurface of Chaco-Paraná basin. Recent radiometric dating provided by other authors revealed ages of 134.7?±?1 and 131.6?±?2.3?Ma for PMP basalts, whereas interbedded acid rocks show 137.3?±?1.8 and 134.3?±?0.8?Ma, respectively. A new .Ar/.Ar dating of 129?±?1?Ma is here presented for the volcan
