Journal ArticleDOI
Melting of Peridotite to 140 Gigapascals
Guillaume Fiquet,Anne-Line Auzende,Julien Siebert,Alexandre Corgne,Alexandre Corgne,Hélène Bureau,Haruka Ozawa,Haruka Ozawa,Gaston Garbarino +8 more
TL;DR: Melting phase relations and element partitioning data show that these liquids could host many incompatible elements at the base of the mantle, such that seismically anomalous zones near the boundary between the core and the mantle may result from isolated pockets of melt.
Journal ArticleDOI
An experimental study of element partitioning between magnetite, clinopyroxene and iron-bearing silicate liquids with particular emphasis on vanadium
TL;DR: In this paper, vanadium partitioning is strongly dependent on oxygen fugacity, decreasing by approximately one order of magnitude with increasing oxygen fugancy, from 0.7 to 2.6 log units above the NNO buffer.
Journal ArticleDOI
Systematics of metal-silicate partitioning for many siderophile elements applied to Earth’s core formation
Julien Siebert,Julien Siebert,Julien Siebert,Alexandre Corgne,Alexandre Corgne,Frederick J. Ryerson +5 more
TL;DR: In this article, the effects of temperature, oxygen fugacity and silicate melt composition on superliquidus metal-silicate partitioning were investigated for a number of moderately siderophile (Mo, As, Ge, W, V, P, Ni, Co, Cr, Zn, Mn and W) and refractory lithophile (Nb, Ta) elements.
Journal ArticleDOI
Silicate perovskite-melt partitioning of trace elements and geochemical signature of a deep perovskitic reservoir
TL;DR: In this article, the authors determined the partitioning of a wide range of trace elements between silicate melts and MgSiO3 perovskites using both laser ablation-ICPMS and ion microprobe techniques.
Journal ArticleDOI
Spin transition and equations of state of (Mg, Fe)O solid solutions
Yingwei Fei,Li Zhang,Alexandre Corgne,Alexandre Corgne,Heather C. Watson,Heather C. Watson,A. Ricolleau,Yue Meng,Vitali B. Prakapenka +8 more
TL;DR: In this article, a series of experiments were performed to investigate the compositional effect on the compression behavior of (Mg, Fe)O solid solutions at high pressure and found abnormal volume contractions at about 40, 60, and 80 GPa.
