Pressure-driven instability in planetary stagnant lids
… resulted in temperatures well in excess of the solidus of silicates, with radiogenic heating also playing a major role. In many cases this results in a partially molten mantle, known as a magma ocean. Both fully solid mantles and magma oceans are noted for their complex fluid dynamics, in …

Thermal evolution of a compositionally stratified earth, including plates
For subduction to occur, plates must bend and slide past overriding plates along fault zones. This deformation is associated with significant energy dissipation, which changes the energy balance of mantle convection and influences the thermal history of the Earth. To parameterize these effects, a …

The Influence of Curvature on Mantle Convection featuring a Temperature-dependent Viscosity
… across the mantle depth (ΔηT). The onset of the stagnant-lid regime occurs for different conditions for bodies with relatively small cores and relatively thin shells. Differences in mean temperature and flow fields observed between 2D and 3D geometry are amplified as relative core-size is …

Geodynamic Modeling Applied to Venus
Modern geodynamic modeling is more complex than ever, and has been used to answer questions about Earth pertaining to the dynamics of the convecting mantle and core, layers humans have never directly interacted with. While the insights gleaned from these models cannot be argued, it is important to …
