TITLE: Mantle plumes, magma dynamics and hotspot volcanism: Insights from computational modeling
I will talk about how chemical trends observed in ocean island chains, such as Hawaii, can be caused by chemical heterogeneities close to the core-mantle boundary sampled by rising mantle plumes. I will present new computational methods for modeling an evolving mineral grain size and the porous flow of magma through a deforming solid rock, and show that both processes substantially influence magma and mantle dynamics. These new methods will enable future research on the focusing of melt to mid-ocean ridges and the role that melting events play in continental break-up.
