Inclusion of osmium in golden items from the South Trans-Ural barrows as indicators of sourses of metal

During the searches of golden items from the south trans-Ural barrows the inclusions of minerals were exposed which represent alloys on osmium, iridium, and ruthenium. There was a conclusion in morphology and the difference in content that the source of metal for the ancient jewelers served osmium-placers confined to the hiper-bazit of the main Ural braking. There is a good convergence of the analysis' results made by X-ray-fluorescent and micro analyzer modes. There is a conclusion that the purposeful research of the content of golden items and conclusions in them will let define the ways of metal diffusion.
