The goal of the researh is to better understand how melts               segregate from the mantle, with particular application to the                   Hawaiian Islands.  The PI plans an analytical and numerical                     study of four model problems: 1) Melt segregation with suction,                 to determine whether melt segregation is driven primarily by                    differential buoyancy or by externally applied pressure                         gradients. 2) A finite-element study of thermal convection with                 melting, to evaluate the influence of latent heat and melt                      byoyancy on the dynamics of convection. 3) Dynamical-chemical                   models for the origin of the Hawaiian Islands, to test two                      possible explanations for the petrological/geochemical evolution                of Hawaiian volcanic: chemical variations across a mantle                       plume, and interaction of the plume with the oceanic                            lithosphere. 4) Melting in ascending thermals, to determine how                 melting occurs in isolated buoyant parcels in the mantle.                       Funding at the revised level is recommended.
