Mantle convection and, by association, plate tectonics is driven by the transport of heat from a planetary interior. This heat comes from the internal energy of the mantle and from heat flowing into the base of the mantle from the core. Past investigations of such mixed mode heating have ...
The evolution of the planetary interior during plate tectonics is controlled by slow convection within the mantle. Global-scale geochemical differences across the upper mantle are known, but how they are preserved during convection has not been adequately explained. We demonstrate that the geographic ...
Mantle convection drives plate tectonics and the size, number and thermotectonic age of plates codetermines the convection pattern. However, the degree of coupling of surface deformation and mantle flow is unclear. Most numerical models of lithospheric deformation are designed such that strain is a ...
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 drives plate tectonics, redistributes heat, cycles chemical species, and generates dynamic topography at the Earth’s surface. Constraining spatio-temporal changes in the thermochemical structure of the mantle will help to refine our understanding of these interlinked phenomena. This signi...
Convection in the earth's mantle: towards a numerical simulation Plate tectonics provides a remarkably accurate kinematic description of the motion of the earth's crust but a fully dynamical theory requires an understanding of convection in the mantle. Thus the properties of plates and of the ...
tectonics/ mantle convectionviscosityplate tectonics/ A9145D Plate tectonicsObservational evidence from glacial rebound and gravity anomalies shows that the mantle has a relatively uniform viscosity. Such a structure is consistent with the effects of temperature and pressure on microscopic mechanisms for ...
Mantle plume tectonics based on whole-mantle convection(MOMO model) , along with plate tectonics provides a new hypothesis for the interpretation of earth deep processes and continental break-up. Within palaeo-Tethyan area, the continental blocks located in Sichuan and western Yunnan provinces experienc...
These and other aspects of the pattern of surface motions associated with mantIe convection have been described kinemati cally within the framework of a set of ideas that has come to be called "plate tectonics." The development of this set of ideas has consummated the revolution at a ...
Plate tectonics and convection in the Earth's mantle: toward a numerical simulation Numerical models of mantle convection are starting to reproduce many of the essential features of continental drift and plate tectonics. The authors show h... L Moresi,M Gurnis,Shijie Zhong, - 《Computing in Scie...
