Paraná and Etendeka traps

The Paraná-Etendeka traps comprise a large igneous province that includes both the main Paraná traps as well as the smaller severed portions of the flood basalts at the Etendeka traps. The original basalt flows occurred 138 to 128 million years ago. The province had a post-flow surface area of 1,500,000 square kilometres and an original volume projected to be in excess of 2.3 x 106 km³.
