Past and Present Dynamics of the Iron Biogeochemical Cycle
Nicolas Dauphas, Andy W. Heard, Eric Siciliano Rego +5
This chapter investigates the complexities surrounding the iron biogeochemical cycle from the Archean to present, with a focus on assessing the balance between iron sources and sin…
Jupiter's influence on the building blocks of Mars and Earth
R. Brasser, N. Dauphas, S. J. Mojzsis
Radiometric dating indicates that Mars accreted in the first ~4 Myr of solar system formation, which coincides with the formation and possible migration of Jupiter. While nebular g…
Thulium anomalies and rare earth element patterns in meteorites and Earth: Nebular fractionation and the nugget effect
N. Dauphas, A. Pourmand
This study reports the bulk rare earth element (REEs, La-Lu) compositions of 41 chondrites, including 32 falls and 9 finds from carbonaceous (CI, CM, CO and CV), enstatite (EH and…
A general moment NRIXS approach to the determination of equilibrium Fe isotopic fractionation factors: application to goethite and jarosite
N. Dauphas, M. Roskosz, E. E. Alp +7
We measured the reduced partition function ratios for iron isotopes in goethite FeO(OH), potassium-jarosite KFe3(SO4)2(OH)6, and hydronium-jarosite (H3O)Fe3(SO4)2(OH)6, by Nuclear…
Neutron-rich chromium isotope anomalies in supernova nanoparticles
Nicolas Dauphas, Laurent Remusat, James Chen +6
Neutron-rich isotopes with masses near that of iron are produced in type Ia and II supernovae. Traces of such nucleosynthesis are found in primitive meteorites in the form of varia…
Nucleosynthetic osmium isotope anomalies in acid leachates of the Murchison meteorite
L. Reisberg, N. Dauphas, A. Luguet +3
We present osmium isotopic results obtained by sequential leaching of the Murchison meteorite, which reveal the existence of very large internal anomalies of nucleosynthetic origin…
