Results for the Os-Ir-Ru alloys, chromitites, and Hoba (IVB) processed through chemistry (as indicated). These data have been corrected using an assumed oxygen isotope composition [32] and correction for mass fractionation using ⁹⁹Ru/¹⁰¹Ru = 0.745075 and the isotopic species. Samples have been compared to the Ru Alfa Aesar standard analyzed during the respective analytical campaign.
