• Differentiated Planetesimals and the Parent Bodies of Chondrites (2013, background): “In support of this possibility, CK and CV meteorites overlap in their oxygen (Greenwood et al. 2010) and possibly their 54Cr/52Cr (Qin et al. 2010, Trinquier et al. 2007) isotopic compositions.”
• Nickel isotope heterogeneity in the early Solar System (2008, methodology): “Nucleosynthetic variations in 54Cr in bulk chondrites are somewhat larger than those in 62Ni (Trinquier et al., 2007), but accurate Cr isotope measurements can only be easily obtained for silicate meteorite types, since some irons contain little Cr, and spallation production of Cr from Fe…”
• EVIDENCE FOR MAGNESIUM ISOTOPE HETEROGENEITY IN THE SOLAR PROTOPLANETARY DISK (2011, background): “…and asteroids, most noticeably for neutron-rich isotopes of the iron-group elements such as 48Ca, 50Ti, 54Cr, and 64Ni (Birck 2004), and are interpreted as reflecting heterogeneous distribution of presolar components in the solar protoplanetary disk (Rotaru et al. 1992; Trinquier et al. 2007).”
• U-Pb chronology of the Solar System's oldest solids with variable 238 U/ 235 U (2010, background): “Recent studies in isotope geochemistry (e.g. Ranen and Jacobsen 2006; Carlson et al. 2007, and Trinquier et al. 2007, 2009, and many other) have established the difference in isotopic composition of many elements between the Earth and chondrites, and isotopic heterogeneity among the chemical…”
• Melting and differentiation of early-formed asteroids: The perspective from high precision oxygen isotope studies (2017, background): “It was pointed out by Warren (2011a,b), based on data from earlier studies (e.g. Shukolyukov and Lugmair, 2006; Trinquier et al., 2007, 2009; Qin et al., 2010a,b), that Solar System materials display a bimodal distribution with respect to a range of stable nuclides, including 54Cr, 50Ti and 62Ni.”
• Correlated accretion ages and ε54Cr of meteorite parent bodies and the evolution of the solar nebula (2014, methodology): “Positive anomalies in stable Cr and Ti isotopes in NWA 2976 reported by Trinquier et al. (2007b) suggest that the parent body has an affinity to carbonaceous chondrites.”
• The Non-carbonaceous–Carbonaceous Meteorite Dichotomy (2020, background): “…anomalies have now been identified for many elements, and it has been shown that they exist not only in bulk carbonaceous chondrites, but also in other groups of meteorites (e.g., Burkhardt et al. 2011; Dauphas et al. 2002; Leya et al. 2008; Regelous et al. 2008; Trinquier et al. 2007, 2009).”
• Heterogeneous accretion, composition and core–mantle differentiation of the Earth (2011, background): “Although primitivemeteorites are representative of early-accreted material, there is no single type of chondritic meteorite that would represent a suitable parental material for the Earth, neither with regard to chemistry nor isotopic composition (Drake and Righter, 2002; Simon and DePaolo, 2010; Tr”

• Stable-isotopic anomalies and the accretionary assemblage of the Earth and Mars: A subordinate role for carbonaceous chondrites (2011, methodology): “Chromium isotopic data are taken from Bogdanovski and Lugmair (2004), Yamashita et al.

• The origins and concentrations of water, carbon, nitrogen and noble gases on Earth (2014, background): “The oxygen (Javoy et al., 1986), chromium (Trinquier et al., 2007), titanium (Leya et al., 2008) and molybdenum (Dauphas et al., 2002) isotope signatures of the Earth point to a enstatite chondrite (EC) composition rather than to a CC ancestor.”
