A diamond-bearing core-mantle boundary on Mercury

Autor: Yongjiang Xu, Yanhao Lin, Peiyan Wu, Olivier Namur, Yishen Zhang, Bernard Charlier

Publikováno v: Nature Communications, Vol 15, Iss 1, Pp 1-9 (2024)

Abstract Abundant carbon was identified on Mercury by MESSENGER, which is interpreted as the remnant of a primordial graphite flotation crust, suggesting that the magma ocean and core were saturated in carbon. We re-evaluate carbon speciation in Merc

Compositional boundary layers trigger liquid unmixing in a basaltic crystal mush

Autor: Victoria C. Honour, Marian B. Holness, Bernard Charlier, Sandra C. Piazolo, Olivier Namur, Ty J. Prosa, Isabelle Martin, Rosalind T. Helz, John Maclennan, Marlon M. Jean

Publikováno v: Nature Communications, Vol 10, Iss 1, Pp 1-8 (2019)

This study seeks to tackle the question of why intermediate magmatic rock compositions are poorly represented on the Earth’s surface. The authors do so by tracking the evolution of the physical behaviour of immiscible Fe-rich liquids within a sampl

Immiscible hydrous Fe–Ca–P melt and the origin of iron oxide-apatite ore deposits

Autor: Tong Hou, Bernard Charlier, François Holtz, Ilya Veksler, Zhaochong Zhang, Rainer Thomas, Olivier Namur

Publikováno v: Nature Communications, Vol 9, Iss 1, Pp 1-8 (2018)

The origin of iron oxide-apatite deposits remains enigmatic and controversial. Here, the authors perform experiments on intermediate magmas and show that increasing aH2O and fO2 enlarges the two-liquid field thus allowing the Fe–Ca–P melt to sepa

Du chasseur au loup, du loup à l’«objet»

Autor: Bernard Charlier

Publikováno v: Swiss Journal of Sociocultural Anthropology, Vol 20 (2015)

This article aims at studying the relationships Mongolian herders who practice hunting entertain with a particular material object, that is a wolf’s ankle bone. I try to show through an ethnographic analysis of the cosmological status of the wolf a

Faces of the Wolf : Managing the Human, Non-human Boundary in Mongolia

Autor: Bernard Charlier

In his study of the human, non-human relationships in Mongolia, Bernard Charlier explores the role of the wolf in the ways nomadic herders relate to their natural environment and to themselves. The wolf, as the enemy of the herds and a prestigious pr

Melting relations for putative mantles of Mercury and the compositional diversity of the crust

Autor: Peiyan Wu, Yongjiang Xu, Yanhao Lin, Bernard Charlier

The compositional diversity of volcanic rocks revealed by NASA’s MESSENGER at the surface of Mercury has been interpreted to result from partial melting of a heterogenous sulfur-rich Mercurian mantle. However, melting relations and the composition
