Composition of the Earth's core: A review 作者:Litasov K D*; Shatskiy A F 来源:Russian Geology and Geophysics, 2016, 57(1): 22-46. DOI:10.1016/j.rgg.2016.01.003 core mantle high pressure iron melt magma ocean silicates 摘要
the bulk composition of the Primitive Mantle. The core’s composition is derived by using a volatility curve for the Earth, based on the Primitive Mantle’s lithophile element abundances, and the chemical systematics seen in chondrites and Fe-meteorites. In all cases the Earth is assumed to ...
RECENTLY, Birchreported data on the density and composition of the mantle and core. He wrote: ``The resulting densities in the lower mantle are found to be in good agreement with shock-wave measurements on rocks having FeO contents in the range 10 +/- 2% by weight ... except for iron ...
Earth, third planet from the Sun and the fifth largest planet in the solar system in terms of size and mass. Its single most outstanding feature is that its near-surface environments are the only places in the universe known to harbor life. Learn more ab
structure of the Earth comprises an upper and lower mantle of similar composition, an Fe Ni core having between 5% and 15% of a low-atomic-weight element, and a mantle which, when compared to CI carbonaceous chondrites, is depleted in Mg and Si relative to the refractory lithophile ...
On the other hand, entry of Si and Mg is not favoured by thermodynamic arguments. Oxygen is the most abundant element in the Earth and would be a prime candidate if it could be shown to be extensively soluble in molten iron at core temperatures and pressures. New experimental data on the...

Iron makes up 5 percent ofEarth’s crust and is second in abundance toaluminumamong the metals and fourth in abundance behindoxygen,silicon, and aluminum among the elements. Iron, which is the chiefconstituentof Earth’s core, is the most abundant element in Earth as a whole (about 35 perc...
