Journal ArticleDOI
Isotopic fractionation and transport mechanisms of Zn in plants
Frédéric Moynier,Sylvain Pichat,Marie-Laure Pons,David A. Fike,Vincent Balter,Francis Albarède +5 more
TL;DR: In this article, the Zn isotopic composition of different components (seeds, leaves, and rhizome, stem and leaves) of lentils (Lens culinaris) and bamboos (Phyllostachys aurea), respectively, was analyzed by MC-ICP-MS.
Journal ArticleDOI
The origin of Zn isotope fractionation in sulfides
TL;DR: Isotope fractionation of Zn between aqueous sulfide, chloride, and carbonate species (Zn2+, Zn(HS)2, Zn ( HS ) 3 -, Zn S 4 2 -,ZnS(HS), ZnCl+ ZnHCO 3 +, and ZnCO3) was investigated using ab initio methods as discussed by the authors.
Journal ArticleDOI
Early Archean serpentine mud volcanoes at Isua, Greenland, as a niche for early life
Marie-Laure Pons,Ghylaine Quitté,Toshiyuki Fujii,Minik T. Rosing,Bruno Reynard,Frédéric Moynier,Chantal Douchet,Francis Albarède +7 more
TL;DR: The Isua Supracrustal Belt, Greenland, of Early Archean age represents the oldest crustal segment on Earth and its complex lithology comprises an ophiolite-like unit and volcanic rocks reminiscent of boninites, which tie Isua supracrustals to an island arc environment.
Journal ArticleDOI
Isotopic evidence for iron mobility during subduction
Baptiste Debret,Baptiste Debret,Marc-Alban Millet,Marie-Laure Pons,Marie-Laure Pons,Pierre Bouilhol,Edward C. Inglis,Helen M. Williams,Helen M. Williams +8 more
TL;DR: In this paper, the authors used Fe stable isotopes (δ56Fe) as a tracer of iron mobility in serpentinites from Western Alps metaophiolites, which represent remnants of oceanic lithosphere that have undergone subductionrelated metamorphism and devolatilization.
Journal ArticleDOI
Zinc isotope evidence for sulfate-rich fluid transfer across subduction zones
Marie-Laure Pons,Baptiste Debret,Pierre Bouilhol,Adélie Delacour,Helen M. Williams,Helen M. Williams +5 more
TL;DR: It is shown that the progressive decrease in δ66Zn with metamorphic grade is correlated with a decrease in sulfur content, which provides strong evidence for the release of oxidized, sulfate-rich, slab serpentinite-derived fluids to the mantle wedge.
