Geochemical and isotopic constraints on the petrogenesis of the Cretaceous alkaline Morro Redondo intrusive complex, Rio de Janeiro, Brazil: implications for alkaline magma genesis

T The Morro Redondo Complex is composed of plutonic and volcanic alkaline rocks. This igneous complex is part of the Poços de Caldas - Cabo Frio Magmatic Alignment (PCCFA). This study aims to contribute to the understanding of the petrogenesis of the rocks in the Morro Redondo complex and, thereb...
