SE4.02 Mantle convection: Geodynamic models of mantle convection: constraints from mantle plume activity

Event Information

Recently, much attention has been focused on the role of mantle plumes as a fundamental mode of mantle convection throughout much of the Phanerozoic. Large igneous provinces (LIPS) are inferred to be the surface expression of plumes originating at the core-mantle boundary impacting on the base of the lithosphere, with a periodicity of 50-75 Myr. Archaean and Proterozoic LIPS also provide evidence for plume events, but perhaps with a longer periodicity than in the last 500 Myr. We invite contributions with an inter-disciplinary perspective from modellers of mantle convection,seismologists, petrologists, geochemists and geodynamicists interested in exploring the role of mantle plumes in the thermal and chemical evolution of the mantle.
