Influence of the Ringwoodite-Perovskite transition on mantle convection in spherical geometry as a function of Clapeyron slope and Rayleigh number [PDF]
Solid Earth, 2011 We investigate the influence on mantle convection of the negative Clapeyron slope ringwoodite to perovskite and ferro-periclase mantle phase transition, which is correlated with the seismic discontinuity at 660 km depth.

Multidisciplinary Constraints on the Thermal‐Chemical Boundary Between Earth's Core and Mantle
Geochemistry, Geophysics, Geosystems, 2022 Heat flux from the core to the mantle provides driving energy for mantle convection thus powering plate tectonics, and contributes a significant fraction of the geothermal heat budget.

Impact of upper mantle convection on lithosphere hyperextension and subsequent horizontally forced subduction initiation [PDF]
Solid Earth, 2020 Many plate tectonic processes, such as subduction initiation, are embedded in long-term (>100 Myr) geodynamic cycles often involving subsequent phases of extension, cooling without plate deformation and convergence. However, the impact of upper mantle

Effective buoyancy ratio: a new parameter for characterizing thermo-chemical mixing in the Earth's mantle [PDF]
Solid Earth, 2015 Numerical modeling has been carried out in a 2-D cylindrical shell domain to quantify the evolution of a primordial dense layer around the core–mantle boundary.

Geochemistry, Geophysics, Geosystems, 2021 Based on the standard view of depth‐increasing viscosity in the mantle of rocky planets, convection in the deep mantle of these planets is expected to become less likely as the size of planet increases.

Геодинамика и тектонофизика, 2021 A geodynamic model of upper mantle convection related to the Pacific subduction zone is mathematically substantiated and applied to investigate the Cretaceous-Cenozoic evolution of Central East Asia (CEA) and the Arctic. We present a solution for the two-

Vertical motion modeling as a result of mantle convection on the Sea of Okhotsk profile [PDF]
Геосистемы переходных зон, 2022 Vertical motions, especially in the active continental margins such as Kuril-Kamchatka transition zone, are still pure studied. One of the factors significantly affecting the amplitudes and directions of vertical motions is mantle convections.

The impact of rheological uncertainty on dynamic topography predictions [PDF]
Solid Earth, 2019 Much effort is being made to extract the dynamic components of the Earth's topography driven by density heterogeneities in the mantle. Seismically mapped density anomalies have been used as an input into mantle convection models to predict the present ...

Non‐adiabaticity in mantle convection [PDF]
Geophysical Research Letters, 2001 Seismic observations indicate that Earth's lower mantle is homogeneous as revealed by smooth depth variations of the bulk sound velocity and Bullen's inhomogeneity parameter η being close to one. Here we show with 3D spherical convection simulations that it should also be non‐adiabatic because a significant proportion of mantle heat sources is internal.

Rapid transition from primary to secondary crust building on the Moon explained by mantle overturn
Nature Communications, 2023 Geochronology indicates a rapid transition (tens of Myrs) from primary to secondary crust building on the Moon. The processes responsible for initiating secondary magmatism, however, remain in debate.
