Paraná and Etendeka traps

From Wikipedia, the free encyclopedia

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]
