Paraná and Etendeka traps

The Paraná and Etendeka traps in Brazil, South America comprise a large igneous province which includes both the main Paraná traps as well as the smaller severed portions of the flood basalts at the Etendeka traps in Namibia and Angola. The original basalt flows occurred 128 x 10⁶ to 138 x 10⁶ years ago. The province had a post-flow surface area of 1.5 x 10⁶ km² and an original volume projected to be in excess of 2.3 x 10⁶ km³.^[1]
