Oceanic island basalts have much lower eruption rates than lavas from large igneous provinces, but a quantitative petrological comparison of lava sources has not been made. Claude Herzberg and Esteban Gazel have examined the composition of Galápagos-related lavas, and conclude that the mantle plumes that generated large igneous provinces in the Permian to Palaeocene periods were hotter and melted more extensively than the plumes that produced modern oceanic islands.
