Time-dependence in 3D mantle convection models
The view of the lower mantle as a ?graveyard? of subducted crust prevailed for decades and was supported by the Hofmann and White (1982) ...
Publications référencées LMV : - ClerVolcWe have developed a new method for implementing subduction that parameterizes the deformation associated with bending of the oceanic lithosphere within a small ... Thermal perturbations caused by large impacts and consequences ...Both are in a region with thin lithosphere, where a mantle plume has been suggested. Hence upper mantle viscosity could be regionally reduced, ... Plumes from the heterogeneous Earth's mantleThis large-scale flow is conceptually similar to a mechanism ad- vocated by King & Anderson (1995, 1998) for the generation of continental flood basalts. Chapter 6 Mantle Convection with Strong Subduction ZonesPROGNOZ-7 was launched into an orbital plane for which the inbound part was at a local time of about 1900 and the inbound orbit moved into the dayside after ... On the state of sublithospheric upper mantle beneath a supercontinentFor instance, the student will build a program to represent convection (in the Earth mantle, in stars or in ocean or atmospheric boundary layers) ... THE PLASMA MANTLE - INISThis tomography-based modelling of the mantle convective flow is equivalent to assuming that the conservation of energy equation has already been 'solved' (at. Numerical Modelling of Buoyancy Induced Flow in Earth's MantleBurdick and Heimberger (1978) derived an upper mantle model for the Western United. States basically from long-period earthquake records. ... tD. Taille des grains et localisation de la déformation dans la lithosphèreMaterial properties for mantle convection consistent with observed surface fields, Journ. Geophys. Res.,. 85, 7031?7044. Kaus, B ... The thermo-chemical evolution of Mars with a strongly stratified mantleAbstract. The Martian mantle probably experienced an early global magma ocean stage. The crystallization and the fractionation and overturn of such a magma ... 7.02 Physics of Mantle Convectionchoice for the function F(r), at least for mantle dynamicists, is the Murnaghan EoS (Murnaghan, 1951) at constant T that allows us to write an EoS for solids of ... Stagnant-lid convection: comparison of viscosity laws and uniform ...A large range of parameters is covered in this study and results that are obtained here for Earth's mantle are actually also relevant for icy. Fluid dynamics of planetary differentiationThe ranges given here take into account the pressure and temperature ranges that are representative of the Earth's mantle and magma oceans, and ...
