Europa's Ocean Translates Interior Tidal Heating Patterns to the Ice‐Ocean Boundary
AGU Advances, 2023 The circulation in Europa's ocean determines the degree of thermal, mechanical and chemical coupling between the ice shell and the silicate mantle. Using global direct numerical simulations, we investigate the effect of heterogeneous tidal heating in the

Global patterns in Earth's dynamic topography since the Jurassic: the role of subducted slabs [PDF]
Solid Earth, 2017 We evaluate the spatial and temporal evolution of Earth's long-wavelength surface dynamic topography since the Jurassic using a series of high-resolution global mantle convection models.

Mantle Convection Moving Plates [PDF]
This demonstration models the manner in which the convection currents in the mantle of the Earth cause movement of the plates. Convection currents in the mantle were thought, for many years, to be solely responsible for plate tectonic movements, with the

Geological Journal, EarlyView.Carbonates from Santos Basin revealed U–Pb ages correlated with basalt ages (A), suggesting that they were formed during magmatic events. These events placed hot CO2 in the reservoir, which, when mixed with carbonate‐rich cold water (B), led to thermal convection, enabling the formation of the U contained in the carbonates.

Nature Communications, 2017 Mantle partial melting produced the volcanic crust of Mercury. Here, the authors numerically model the formation of post-impact melt sheets and find that mantle convection was weak at around 3.7–3.8 Ga and that the melt sheets of Caloris and Rembrandt ...

On the global geodynamic consequences of different phase boundary morphologies [PDF]
Solid EarthPhase transitions can influence mantle convection patterns, inhibiting or promoting vertical flow. One such transition is the ringwoodite-to-bridgmanite plus periclase transition, which has a negative Clapeyron slope and therefore reduces mantle flow ...

Thermal and electrical conductivity of iron at Earth's core conditions [PDF]
, 2012 The Earth acts as a gigantic heat engine driven by decay of radiogenic isotopes and slow cooling, which gives rise to plate tectonics, volcanoes, and mountain building.

Journal of Vinyl and Additive Technology, Volume 31, Issue 2, Page 441-452, March 2025.Three poly(caprolactone) (PCL)‐based additives of differing molecular weights were used as a secondary plasticizer to prevent gas checks in PVC films produced through calendering. Results showed that chemical and physicochemical properties influence the prevention or reduction of gas checks, unlike rheological properties including complex viscosity and
