• Spinel–olivine magnesium isotope thermometry in the mantle and implications for the Mg isotopic composition of Earth (2009, result): “Ourmeasured δ25Mg values relative to DSM3 for olivine andwhole rocks representing two San Carlos mantle xenoliths are in good agreement with values for mantle xenolith olivine reported by Handler et al. (2009) and Bizzarro et al. (2005).”
• Prograde rotation of protoplanets by accretion of pebbles in a gaseous environment (2009, background): “Accumulation of differentiated meteorite parent bodies must occur while 26Al and 60Fe are still present in the solar nebula, constraining their formation time to at most a million years after the formation of calcium-aluminium-rich inclusions (Bizzarro et al. 2005; Yang, Goldstein, & Scott 2007).”
• Chronology of the Solar System’s Oldest Solids (2008, background): “…younger accretion age of the CR parent body that could be implied by lower peak metamorphic temperatures compared to that of the CV chondrite parent body (Scott 2007), assuming that 26Al was an important heat source for planetesimal differentiation (Bizzarro et al. 2005; Baker et al. 2005).”
• Hf-W chronology of the accretion and early evolution of asteroids and terrestrial planets (2009, background): “These are the parent bodies of some magmatic iron meteorites and possibly also the eucrites and angrites, as indicated by their 26Al–26Mg systematics (Bizzarro et al., 2005).”
• Hf–W mineral isochron for Ca,Al-rich inclusions: Age of the solar system and the timing of core formation in planetesimals (2008, background): “Based on the observation that several differentiated meteorites (including magmatic iron meteorites) exhibit a small deficit in (60)Ni, it was suggested that their parent bodies formed prior to the injection of (60)Fe that occurred 1 Myr after CAI formation (Bizzarro et al., 2007).
