• Turbulent Mixing of Metal and Silicate during Planet Accretion – and interpretation of the Hf-W chronometer (2010, background): “Isotopic evidence from meteorites reveals that core formation is fast (∼1 Myrs) in some small (10 km) bodies (Chen andWasserburg, 1996; Lee and Halliday, 1996;Markowski et al., 2006).”
• Nickel isotope heterogeneity in the early Solar System (2008, methodology): “This is unexpected, given the rapid timescales of planetesimal iron meteorite formation implied byW isotope studies (Kleine et al., 2005; Scherstén et al., 2006; Markowski et al., 2006a).”
• Chondrules and the Protoplanetary Disk (2011, methodology): “When corrections are made for cosmic ray exposure effects in meteoroids, metal-silicate separation occurred 0.3 ± 1.5 Myr after CAIs formed (Kleine et al. 2005, Markowski et al. 2006).”
• Hf–W mineral isochron for Ca,Al-rich inclusions: Age of the solar system and the timing of core formation in planetesimals (2008, methodology): “…employed correction methods rely on the isotopic composition of noble gases and must make assumptions regarding several parameters including the pre-atmospheric size of the meteoroid and the shielding depth of a particular sample (Leya et al., 2003; Markowski et al., 2006a; Qin et al., 2008b).”
• Chronology of the angrite parent body and implications for core formation in protoplanets (2012, background): “As evident from strong (182)W deficits in most magmatic iron meteorites, core formation in their parent bodies must have occurred within 1 Myr after formation of Ca,Al-rich inclusions (CAI) (Kleine et al., 2005a; Markowski et al., 2006; Scherstén et al., 2006; Burkhardt et al., 2008; Qin et al., 200”
• Emergence of a Habitable Planet (2007, background): “The latest data for iron meteorites provide evidence that accretion and core formation were very short-lived (Kleine et al. 2005a; Markowski et al. 2006; Scherstén et al. 2006).”
