Melting and melt migration in heterogeneous mantle beneath mid-ocean ridges

Abstract:

Evidence for chemical heterogeneity in the mantle is widespread in oceanic basalts, yet its consequences for basalt petrogenesis are little understood. A significant unknown is the effect that heterogeneity has on the dynamics of magma flow in the mantle. Observations of oceanic crust and the upper mantle suggest that magma migrates to the surface through a network of high porosity channels. In this thesis, I use computational models of coupled magma/mantle dynamics beneath mid-ocean ridge...
