Seismic and gravitational studies of melting in the mantle's thermal boundary layers
(Massachusetts Institute of Technology, 2007)
This thesis presents three studies which apply geophysical tools to the task of better understanding mantle melting phenomena at the upper and lower boundaries of the mantle. The first study uses seafloor bathymetry and ...
Geochemical and rheological constraints on the dynamics of the oceanic upper mantle
(Massachusetts Institute of Technology, 2007)
I provide constraints on mantle convection through observations of the rheology and composition of the oceanic upper mantle. Convection cannot be directly observed, yet is a fundamental part of the plate tectonic cycle. ...
