Interactions between mantle plumes and mid-ocean ridges : constraints from geophysics, geochemistry, and geodynamical modeling
… interactions between mid-ocean ridges and mantle plumes using geophysics, geochemistry, and geodynamical modeling. Chapter 1 investigates the effects of the Marion and Bouvet hotspots on the ultra-slow spreading, highly-segmented Southwest Indian Ridge (SWIR). Gravity data indicate that …

Effects Of Subduction History On Mantle Convection: Implications For True Polar Wander And Dynamic Topography
… is the subduction of oceanic crust into the mantle along convergent margins; this process of recycling Earth materials destroys the geological data used to reconstruct plate history. To reconcile the long-debated subduction history of the circum-Pacific, this study implements two contrasted …

New Constraints For Convergent Margin Plate Tectonic Reconstructions From Imaged And Predicted Mantle Structure
… plate reconstructions from imaged and predicted mantle structure using seismic tomography and forward geodynamic models, respectively. We apply recently-developed P-wave tomographic filtering to create ‘synthetic tomography’ of the geodynamic models. East Asia is one the most uncertain areas in …

On the Viscoelastic Deformation of the Earth
Post-seismic deformation and glacial isostatic adjustment are two processes by which the Earth deforms viscoelastically. In both cases, the details of the deformation depend on the rheological structure of the Earth as well as the forcing, which is the earthquake and further movement on the fault …

The evolution of the Greenland Ice Sheet from the Last Glacial Maximum to present-day: An assessment using glaciological and Glacial Isostatic Adjustment modelling
… are highly sensitive to variations of upper mantle viscosity. Depending on the Earth model adopted, different periods of post-LGM ice loading change dominate the present-day response in particular regions of Greenland. These results will be a useful resource when interpreting existing and …
