Theories of the formation of flood basalts must explain how such vast amounts of magma could be generated and erupted as lava in such short … See more

Large Igneous Provinces (LIPs) were originally defined as voluminous outpourings, predominantly of basalt, over geologically very short durations. This definition did not specify minimum size, duration, petrogenesis, or setting. A new attempt to refine … See more
