In order to provide further insights into the origin of Ru-Os-Ir alloys, this study presents new highly siderophile element (HSE: Re, Os, Ir, Ru, Pt, and Pd) abundance and 187 Re- 187 Os and 190 Pt- 186 Os isotope data for detrital grains of native Ru-Os-Ir alloys in placer deposits of the Kunar and...
