Journal ArticleDOI
Solidus and liquidus profiles of chondritic mantle: Implication for melting of the Earth across its history
Denis Andrault,Nathalie Bolfan-Casanova,Giacomo Lo Nigro,Mohamed Ali Bouhifd,Gaston Garbarino,Mohamed Mezouar +5 more
TL;DR: In this paper, the melting properties of a synthetic chondritic primitive mantle up to core-mantle boundary (CMB) pressures were investigated using laser-heated diamond anvil cell.
Journal ArticleDOI
Thermal expansion of forsterite up to the melting point
TL;DR: The thermal expansion coefficient of forsterite increases smoothly from 2.8 to 4.5 K−1 from 400 K to 2160 K as discussed by the authors, indicating that defects do not make a large contribution to thermal expansion near the melting point.
Journal ArticleDOI
Melting of subducted basalt at the core-mantle boundary.
Denis Andrault,Giacomo Pesce,Mohamed Ali Bouhifd,Nathalie Bolfan-Casanova,Jean-Marc Hénot,Mohamed Mezouar +5 more
TL;DR: The melting properties of mid-oceanic ridge basalt (MORB), which can reach the lowermost mantle after subduction of oceanic crust, are explored and the major mineral phase of the lower mantle decomposes into two minerals are found.
Journal ArticleDOI
Metal–silicate partitioning of sulphur, new experimental and thermodynamic constraints on planetary accretion
A. Boujibar,A. Boujibar,Denis Andrault,Denis Andrault,Mohamed Ali Bouhifd,Mohamed Ali Bouhifd,Nathalie Bolfan-Casanova,Nathalie Bolfan-Casanova,Jean-Luc Devidal,Jean-Luc Devidal,Nicolas Trcera +10 more
TL;DR: In this paper, the authors show that if S is accreted along the accretion path, its distribution between core and mantle can lead to the observed S concentration of the mantle (200 ± 80 ppm ) and to the estimations of S content of the core (from its depletion in the mantle relative to the other elements with the same volatility).
Journal ArticleDOI
Convergence of Ni and Co metal-silicate partition coefficients in the deep magma-ocean and coupled silicon-oxygen solubility in iron melts at high pressures
TL;DR: In this article, metal-silicate partitioning experiments were performed for pressures up to ~ 52 GPa and ~ 3500 K to investigate the behavior of Ni and Co during terrestrial core formation using Laser-Heated Diamond-Anvil Cell (LHDAC) techniques.
