“…As mentioned earlier, planetary-scale, stable isotope anomalies are found in meteorites for various elements (e.g., Cr, Ti, Mo, Ru, and Ba), including Sr, whereas isotope homogeneity can be observed for some selected elements (e.g., Cd, Te, Hf, and Os). Interestingly, the elements that exhibit isotope anomalies are moderately refractory elements with 50% condensation temperatures ranging from ∼1300 to ∼1600 K (Lodders, 2003), whereas moderately volatile elements (Cd and Te: Fehr et al, 2005;Wombacher et al, 2008) and ultrarefractory elements (Hf and Os: Sprung et al, 2010;Yokoyama et al, 2010) show no isotope anomalies, except for one ultrarefractory element, Zr (Akram et al, 2013). Further investigation with more precise and accurate isotope data for the elements in bulk meteorites with a wide range of condensation temperatures would provide clues for understanding the dynamic evolution of the dust grains and subsequent planetary formation in the early solar system.…”
