Early Cretaceous Volcanism in Central and Eastern Argentina During Gondwana Break-Up (Paperback, 1st ed. 2016)

This book analyzes the Early Cretaceous volcanic processes in Misiones Province and in Sierra Chica de Cordoba (Argentina). The volcanism in Misiones is tholeiitic and belongs to the Parana Magmatic Province (PMP), which extends throughout South America. In contrast, the volcanism in Cordoba is geographically restricted and of alkaline nature, representing a potassic locality peripheral to the PMP. To understand the causes of and geodynamic processes involved in these volcanisms, a new 40Ar /39Ar of 129.6 +/- 1 Ma of a trachyte from Sierra Chica de Cordoba is presented. This dating points out that the volcanism in Sierra Chica de Cordoba slightly postdates PMP lavas. Moreover, complementary geochemical analyses from Misiones Province are presented and compared with those from the whole PMP in order to characterize its source
