Astrophysics with Extraterrestrial Materials (2016, background): “…in various elements (e.g., Ca, Ti, Mo, Ba, Cr, osmium) seen at the scale of CAIs, bulk meteorites, and/or stepwise dissolution of bulk meteorites (Carlson et al. 2007 and references therein, Trinquier et al. 2009, Qin et al. 2010, Chen et al. 2011, Brennecka et al. 2013, Dauphas et al. 2014).”
Planetary and meteoritic Mg/Si and δ30Si variations inherited from solar nebula chemistry (2015, background): “t al. (2014) also reported Si isotope data of angrites and interpreted their measurements in terms of impact-induced Si volatilization on the angrite parent-body (APB). Based on our results (also see Dauphas et al., 2014b), we provide an alternative explanation and show that Mg/Si and variations in ”
The Non-carbonaceous–Carbonaceous Meteorite Dichotomy (2020, background): “This suggests that Earth predominantly accreted from material with an enstatite chondrite-like isotopic composition (Dauphas 2017; Dauphas et al. 2014), in which case the BSE’s Mo isotopic composition most likely reflects a mixture of this material with s- process–enriched material from the CC…”
