Early Cretaceous Volcanism in Eastern Argentina,n only for the Gramado variety, in agreement with the general trend recognized in the PMP. Geochemical features point out that different ancient subduction processes could have affected the source of the PMP basalts from Misiones Province, as those that occurred during Late Proterozoic–Early Cambria

Cratons and other continental domains older than the Late Palaeozoic were also considered, taking into account that the Early Cretaceous volcanism in South America and Africa could hav

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
