Geochemistry of mantle–core differentiation at high pressure
Jie Li,Carl B. Agee +1 more
TL;DR: In this paper, it was shown that the absolute and relative abundances of Ni and Co in the Earth's mantle are consistent with alloy-silicate chemical equilibrium at high pressure, indicating that core formation may have taken place in a magma ocean with a depth of 750-1,100 km.
Journal ArticleDOI
Experimentally determined postspinel transformation boundary in Mg2SiO4 using MgO as an internal pressure standard and its geophysical implications
Yingwei Fei,J. Van Orman,J. Van Orman,Jie Li,Jie Li,W. van Westrenen,W. van Westrenen,Chrystele Sanloup,Chrystele Sanloup,William G. Minarik,Kei Hirose,Tetsuya Komabayashi,Michael J. Walter,Ken-ichi Funakoshi +13 more
TL;DR: In this article, the postspinel transformation boundary in Mg2SiO4 was determined by combining quench technique with in situ pressure measurements, using multiple internal pressure standards including Au, MgO, and Pt.
Journal ArticleDOI
Structure type and bulk modulus of Fe3S, a new iron-sulfur compound
TL;DR: In this paper, a series of experiments in the system Fe-FeS at a pressure of 21 GPa and temperatures between 950 and 1400 °C were performed, and two new iron-excess iron-sulfur compounds, Fe3S and Fe2S, formed at subsolidus temperatures.
Journal ArticleDOI
Pressure‐temperature phase diagram for the Allende meteorite
TL;DR: In this paper, Zhang and Herzberg showed that a terrestrial planet with a radius of ∼3000 km (maximum internal pressure of ∼30 GPa), and a bulk composition of carbonaceous chondrite, will upon magmatic differentiation form an FeO-rich silicate mantle with an Fe-Ni-S core.
Journal ArticleDOI
Electronic spin state of iron in lower mantle perovskite
Jie Li,Viktor V. Struzhkin,Ho-kwang Mao,Jinfu Shu,Russell J. Hemley,Yingwei Fei,Bjorn O. Mysen,P. Dera,Vitali B. Prakapenka,Guoyin Shen +9 more
TL;DR: Experimental evidence for spin-pairing transition in aluminum-bearing silicate perovskite (Mg,Fe)(Si,Al)O(3) under the lower mantle pressures is presented and it is demonstrated that as pressure increases, iron in perovkite transforms gradually from the initial high- spin state toward the final low-spin state.
