The scaling of plate-tectonic convection is investigated by simulating thermal convection with pseudoplastic rheology and strongly temperature-dependent viscosity. The effect of mantle melting is also explored with additional depth-dependent viscosity. Heat-flow scaling can be constructed with only two parameters, the internal Rayleigh number and the lithospheric viscosity contrast, the latter of which is determined entirely by rheological properties. The critical viscosity contrast for the…

Mantle rheology and the scaling of bending dissipation in plate tectonics
[1] Plate tectonics on Earth involves the bending deformation of plates at subduction zones, and because plates are generally considered to be stiff owning to the rheology of mantle minerals, the
Influence of realistic rheological properties on the style of mantle convection: roles of dynamic friction and depth-dependence of rheological properties
In order to generate plate tectonics, the near surface layer should not be too strong, but the causes for not-so-strong near surface layer remains unclear. We conduct mantle convection modelling in
Numerical model for the generation of the ensemble of lithospheric plates and their penetration through the 660-km boundary
In the kinematic theory of lithospheric plate tectonics, the position and parameters of the plates are predetermined in the initial and boundary conditions. However, in the self-consistent dynamical
Towards scaling laws for subduction initiation on terrestrial planets: constraints from two-dimensional steady-state convection simulations
The strongly temperature-dependent viscosity of rocks leads to the formation of nearly rigid lithospheric plates. Previous studies showed that a very low yield stress might be necessary to weaken and

The importance of understanding the microphysics of plate boundary formation for assessing early Earth tectonics is highlighted, as different plate Boundary formation mechanisms are influenced by mantle thermal state in fundamentally different ways.
Scaling laws for convection with temperature-dependent viscosity and grain-damage
Numerical experiments of convection with grain-damage are used to develop scaling laws for convective heat flow, mantle velocity, and plate velocity across the stagnant lid and plate-tectonic
Influence of magmatism on mantle cooling, surface heat flow and Urey ratio
Two-dimensional thermo-chemical mantle convection simulations are used to investigate the influence of melting-inducted differentiation on the thermal evolution of Earth's mantle, focussing in
Initiation of plate tectonics from post-magma ocean thermochemical convection
Leading theories for the presence of plate tectonics on Earth typically appeal to the role of present day conditions in promoting rheological weakening of the lithosphere. However, it is unknown
A preliminary numerical study on water-circulation in convecting mantle with magmatism and tectonic plates
Abstract We present a preliminary self-consistent numerical model of solid-state convection in a wet mantle with magmatism and tectonic plates to understand how magmatism and tectonic plates affect
Thermal evolution with a hydrating mantle and the initiation of plate tectonics in the early Earth
[1] The net influx of water into the deep mantle by plate tectonics has been poorly constrained because it is difficult to quantify how efficiently subducting slabs are devolatilized on a global


Scaling of stagnant-lid convection with Arrhenius rheology and the effects of mantle melting
SUMMARY On the basis of numerical modelling and scaling analysis, a few modifications are proposed for the scaling of stagnant-lid convection, in order to make it more applicable to the thermal
The effect of rheological parameters on plate behaviour in a self-consistent model of mantle convection
Abstract In a three-dimensional numerical model of mantle convection we have explored the self-consistent formation and evolution of plates. This was done by investigating the influence of
Mantle convection with a brittle lithosphere: thoughts on the global tectonic styles of the Earth and Venus
SUMMARY Plates are an integral part of the convection system in the fluid mantle, but plate boundaries are the product of brittle faulting and plate motions are strongly influenced by the existence
Generation of plate‐like behavior and mantle heterogeneity from a spherical, viscoplastic convection model
[1] How plate tectonics arises from mantle convection is a question that has only very recently become feasible to address with spherical, viscoplastic computations. We present mainly internally

Abstract In the last decade, significant progress has been made toward understanding how plate tectonics is generated from mantle dynamics. A primary goal of plate-generation studies has been the
Effect of plate bending on the Urey ratio and the thermal evolution of the mantle
Abstract The bending of tectonic plates as they subduct causes resistance to plate motions and mantle convection. It has been proposed that this effect could keep plate velocities relatively constant
