Advances in our understanding of Earth's thermal evolution and the style of mantle convection rely on robust seismological constraints on lateral variations of density. The largelow-shear-wave velocity provinces (LLSVPs) atop the core-mantle boundary beneath Africa and the Pacific are the largest ...
A mineralogical model for density and elasticity of the Earth's mantle [1] We present a thermodynamic model of high-pressure mineralogy that allows the evaluation of phase stability and physical properties for the Earth's mant... AS Piazzoni,G. Steinle‐Neumann,H.‐P. Bunge,... - 《...

On the origin and constitution of the upper part of the earth's mantle The author proves that the Dirac-Gilbert equation serving as a basis for the expansion theory has the consequence that the Earth's mantle must be, excepting the uppermost 200 kilometres, similar in constitution to a magma...
Three-dimensional density model of the Earth's crust and the upper mantle for the area of Poland. J. Geodyn. 25, 5 - 24.Grabowska, T., Bojdys, G. & Dolnicki, J., 1998. Three-dimensional density model of the Earth's crust and the upper mantle for the area of Poland, J. ...
Motion of hotspots and changes of the Earth's rotation axis caused by a convecting mantle. Advection of mantle density heterogeneities was used to infer changes of the non-hydrostatic moment of inertia tensor and corresponding changes of the rotation axis. Results were compared with paleomagnetic re...

Understanding magmatic processes and their evolution in the Earth's interior requires a better knowledge of silicate melts and their physical properties. Among them, density is one of the most important to constrain the residence or ascent time of magma in the upper mantle and crust. However, ...

The formation of the earth's core was due to the density differentiation of the primitive matter of the earth. This differentiation should be in progress at the core-mantle interface in the present epoch. Redistribution of substances of various densities gives rise to large-scale convective ...
