Carbon distribution in planet Mercury from magma ocean evolution to graphite crust and core composition

Olivier Namur, Bernard Charlier, Camille Cartier, Kaustubh Hakim et autres

MESSENGER observations revealed a primary graphite flotation crust on Mercury, implying substantial carbon retention in its magma ocean rather than sequestration into the core. To investigate the conditions enabling this retention, we conducted high-pressure, high-temperature metal–silicate partitioning experiments over a wide range …

Neodymium, Hf, Os, and U Pb isotope study of Permian Komatiites from Mashhad, Iran

M. Mobasheri, I.S. Puchtel, Maud Boyet, N.T. Arndt et autres

We present new Sm Nd, Lu Hf, Re Os, and U Pb zircon isotopic and highly siderophile element (HSE: Os, Ir, Ru, Pt, Pd, Re) abundance data for komatiites from the Mashhad–Fariman region in Iran, and use these data to constrain their …

The Moon-forming impactor Theia originated from the inner Solar System

Timo Hopp, Nicolas Dauphas, Maud Boyet, Seth A. Jacobson et autres

The Moon formed from a giant impact of a planetary body, called Theia, with proto-Earth. It is unknown whether Theia formed in the inner or outer Solar System. We measured iron isotopes in lunar samples, terrestrial rocks, and meteorites representing the isotopic …

How the Earth's Core and Mantle are Separated

J. Monteux, Maud Boyet

The separation of the Earth's core and mantle is a highly energetic process that took place during or just after the Earth's major accretionary stage. Petrological and geochemical data now enable us to better constrain the physical properties and chemical composition of …
