we argue that the longevity of mantle plumes in the Earth is a consequence of the interactions between plate tectonics, core cooling, and dense, low-vis... AM Jellinek - 《Reviews of Geophysics》 被引量: 179发表: 2004年 Ab-initio chemical potentials of solid and liquid solutions and the ...
The composition of the Earth's core remains an open question. We know that the primary constituent is iron (Fe), but seismological profiles suggest that the density of the outer core is about 10% less than that of pure iron. To account for that, lower atomic weight elements have been sug...
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...
On the Composition and Temperature of the Terrestrial Planetary Core The existence of liquid cores of terrestrial planets such as the Earth, Mar, and Mercury has been supported by various observation. The liquid state of the core provides a unique opportunity for us to estimate the temperature of...
Fahrenheit. Moving from the inner core outward, the temperature of Earth's layers tends to decrease. The upper and lower mantle make up Earth's largest layer. The lower mantle is a solid but flows over very long periods of time due to the extreme temperatures radiating out of the core. ...
Composition of the Earth 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 th... B Mason - 《Nature》 ...
