mantle convectiontectonic platetectonic platesA simple three-dimensional spherical model of mantle convection, where plates are taken into account in the top boundary condition, allows to investigate the plate tectonics鈥搈antle convection coupling in a self-consistent way. Avoiding the strong difficulties...
tectonic units/ A9135 Earth interior A9145D Plate tectonics A9330D AsiaThe Runcorn stress equations and 2–30° harmonic coefficients of the geopotential have been applied to determine the mantle convection pattern beneath China. The pattern is compared with geophysical and geological observations and ...

Mantle Convection and Surface Expressionsbrings together perspectives from observational geophysics, numerical modelling, geochemistry, and mineral physics to build a holistic picture of the deep Earth. It explores the dynamic processes occurring in the mantle as well as the associated heat and material c...
Tectonophysics: Plate tectonicsA system in which convection takes place in the upper mantle on two distinct horizontal length scales is proposed. This is consistent with the existence of the plates themselves, the relatively constant heat flux background in older ocean basins, and the knowledge of ...

Chapter 8 begins with a discussion of plate tectonics. Then the study of convection in the Earth’s mantle is introduced by the consideration of Rayleigh–Bénard convection with constant viscosity. Linear and nonlinear stability are discussed, and the formation of planforms, and then the boundary...
The correlation of convergent plate boundaries with the descent of tectonic plates into the Earth’s interior, in the form of cold subducted slabs, is a core tenet of the plate tectonics paradigm and is required as a corollary to the theory of mantle convection. Subducted slabs are the cold ...
tectonics. The Earth’s outer, rigid shell is broken up into pieces called tectonic plates. The plates are propelled by the mantle convection currents below. The continents are embedded in these plates, and are carried along as the plates ...
The solid-state convection in the Earth mantle is characterized by plate tectonics, which shapes the tectonic activities of the Earth, and superplumes as broad hot regions chemically distinct from the surrounding regions in deep lower mantle. Recent numerical studies of mantle convection suggest that...
