• Hf-W thermochronometry: Closure temperature and constraints on the accretion and cooling history of the H chondrite parent body (2008, methodology): “Hafnium–tungsten chronometry has been applied widely to determine the timescales of differentiation of asteroids and terrestrial planets (Harper and Jacobsen,1996; Schoenberg et al., 2002; Yin et al., 2002; Halliday, 2004; Kleine et al., 2004b; Jacobsen, 2005; Nimmo and Agnor, 2006; Nimmo and Klei”
• The early differentiation history of Mars from 182W-142Nd isotope systematics in the SNC meteorites (2005, methodology): “Isolation of W was performed using a column chromatography procedure (Table 1) similar to that used by previous investigators (Kraus et al., 1955; Horan et al., 1998; Münker et al., 2001; Schoenberg et al., 2002).”
• A Perspective from Extinct Radionuclides on a Young Stellar Object: The Sun and Its Accretion Disk (2011, background): “However, these measurements were later shown to be erroneous (Kleine et al. 2002, Schoenberg et al. 2002, Yin et al. 2002).”
• The cosmic molybdenum–ruthenium isotope correlation (2004, background): “Core formation occurred while Hf (t1/2=9 Ma) was still alive (2e radiogenic W in the Earth’s mantle, relative to chondritic composition), within a few tens of million years of solar system formation [31,37–39].”
• Water and astrobiology (2007, methodology): “Earth was assembled in this violent fashion over a period probably no longer than 30–50Myr following the onset of nebular condensation, based on Hf-W isotopic evidence that Earth’s core had formed by this time (Schoenberg et al., 2002; Yin et al., 2002; Kleine et al., 2002; Jacobsen, 2005, Halliday ”
