Abstract

The Mesozoic acid volcanic rocks of the Namibe basin are concentrated along the continental margin and are characterized by voluminous sheet-like bodies overlying the tholeiitic basalts. The igneous rocks of SW Africa correspond in petrology and Sr-Nd isotope compositions with those of Lower Cretaceous age (135 +- 3 m.y.) in the N Parana basin of SE Brazil and appear to represent the easterly extension of the vast volcanic activity of the Parana basin which occurred before the opening of the S Atlantic Ocean.
