These findings in combination with the proposed breakup age in the early Valanginian that considerably predates the formation of the Paraná–Etendeka continental flood basalt provinces in Brazil and ...

ABSTRACT: The Paraná Continental Flood Basalt (PCFB) province is one of the largest igneous provinces on Earth, but little is known about the architecture and geochemical characteristics of the lava ...

These findings correspond with the characteristics of continental rift basalts. The geochemical analysis hints that the older basalts and diabases were likely derived from the asthenospheric mantle, ...
