Modem metallogenic generalization concerning approximately the 1000 km long Platinum-bearing Belt of the Urals (PBBU) evidently testifies a close spatial and temporal connection of complicatedly composed zonal complexes, forming this belt, mainly of ultramafic content, with the deposits of platinum group metals, chromites, titanomagnetites, coppersulphide mineralization, and makes it possible to consider this association as a united ore-geochemical system. Analysis of the first obtained «in situ» U-Pb SHRIMP isotopic data for zircons extracted from plagiogranite of the Kytlym massif of PBBU, in combination with other geological facts, sets the additional age and isotope-genetic constrains on the available ideas of the evolution, at least, of the middle part of PBBU.
