Journal ArticleDOI
Tungsten isotopic compositions of iron meteorites: Chronological constraints vs. cosmogenic effects
TL;DR: In this article, high-precision W isotopic compositions are presented for 35 iron meteorites from 7 magmatic groups (IC, IIAB, IID, IIIAB, IIIF, IVA, and IVB) and 3 non-magmatic groups.
Journal ArticleDOI
Super-chondritic Sm/Nd ratios in Mars, the Earth and the Moon
TL;DR: High-precision 142Nd data for 16 martian meteorites are presented and it is shown that Mars also has a non-chondritic composition, similar to the putative endmember component ‘FOZO’ characterized by high 3He/4He ratios.
Journal ArticleDOI
New half-life measurement of 182Hf: improved chronometer for the early solar system.
Christof Vockenhuber,Felix Oberli,Max Bichler,I. Ahmad,Ghylaine Quitté,Martin Meier,Alex N. Halliday,Der-Chuen Lee,Walter Kutschera,Peter Steier,R. J. Gehrke,R. G. Helmer +11 more
TL;DR: The greatly improved precision of this half-life now permits very precise intercalibration of the 182Hf-182W isotopic system with other chronometers.
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
Correlated helium-3 and tungsten isotopes in iron meteorites: Quantitative cosmogenic corrections and planetesimal formation times
TL;DR: In this paper, the first experimental evidence of cosmogenic effects on W isotopes in two magmatic iron meteorites, Carbo (IID) and Grant (IIIAB), was presented.
