Installation of the Neptune MC-ICPMS has been completed.
Nicolas Dauphas and Vincent Busigny have published 2 papers presenting new applications of Fe isotope systematics (see Articles section). In one of these papers, the authors showed that paleofluid circulations can be traced using variations in the isotopic composition of iron. In the other, iron isotopes were used to identify the protoliths of heavily metamorphosed chemical sediments (BIFs) in a recently discovered >3.75 Ga supracrustal belt located in Northern Quebec.
A Neptune MC-ICPMS has been delivered at the Origins Laboratory. We hope to have it fully operational by the end of January.
A review paper on Fe isotope systematics has been published. It contains a compilation of Fe isotope measurements in geostandards and theoretical developments on multiphase isotope distillation and the theory of isotopic fractionation during phase growth in a diffusion-limited regime. [Mass Spectrometry Reviews 25, 515-550].
After completion of his postdoc at the OL, Vincent Busigny went back to France. On April 10, he became the father of Lucas. On May 9, he obtained an assistant professor position at the prestigious Institut de Physique du Globe in Paris. Congratulations!
37th Lunar and Planetary Science Conference. Liping Qin reported new measurements of W isotopes in iron meteorites. Vincent Busigny showed how iron isotopes in hematite concretions can be used to infer the direction and scale of paleofluid flows. Nicolas Dauphas reported Fe isotope measurements in recently discovered >3.76 Ga BIFs from Northern Quebec.
68th Annual Meeting of the Meteoritical Society. Liping Qin reported new measurements of W isotopes in iron meteorites to estimate the timing of metal silicate differentiation in asteroids. Vincent Busigny showed how iron isotopes can be used to decipher the formation history of hematite spherical concretions from Utah, which are some of the best terrestrial analogues of martian blueberries. Nicolas Dauphas presented a new method to determine the age of the Milky Way and the U/Th production ratio in stars.
Vincent Busigny and Nicolas Dauphas went on a field trip in Utah to collect moqui marbles, which are spherical hematite concretions that share similarities with martian blueberries.
Nicolas Dauphas presented a new method to determine the age of the Milky Way (14.5 Gyr) and the U/Th production ratio in stars (0.571) based on measurements of meteorites and low metallicity stars from the halo of the Galaxy [Nature 435, 1203-1205].
Nicolas Dauphas and colleagues from Nancy (France) and Chicago (USA) reported Fe isotope measurements of controversial metamorphic rocks from southern West Greenland (Isua, Akilia, and Innersuartuut) dated at around 3.8-3.9 Gyr BP. These results show that the rocks are sedimentary in origin. The isotopic variations are compatible with the transport, oxidation, and subsequent precipitation of ferrous iron emanating from hydrothermal vents [Science 306, 2077-2080].
