CAMP and Pangea.  The Central Atlantic Magmatic Province is defined by flood basalts and other igneous rocks that share the same age (~200 Ma) and similar chemical compositions.  Although igneous rocks do not currently cover the entire area shown in red and orange above, there are dikes in these areas, and dikes are the feeders to eruptive fissures such as produced the Laki and Krafla flood basalts in Iceland.  Therefore, CAMP is the largest large-igneous province, and may have played some role in the mass extinction at the Triassic-Jurassic boundary.
