This study presents the first Hf-isotope data for Precambrian zircons from platinum-bearing dunites of the Nizhny Tagil (Middle Urals) and Guli (Polar Siberia) massifs. The Hf-isotope values and Hf-model ages of the analyzed zircons identify similar Hf-isotope evolution of the silicate material studied. The Hf-isotope data for zircons at Nizhny Tagil and Guli located in different geodynamic settings (mobile belt and stable platform, respectively) are consistent with a global nature of their Neoarchean source.
