In the Uralian type of ores firstly connected with dunite members of the Urals Platinum Belt complexes on the base on mineralogical-geochemical and structural-geological criterions three discrete Pt-ore subtypes have been distinguished: chromite (with coarse and average metal), dunite (with small and average metal), pegmatite (with fine and dust-like metal). On the base of investigations of eguiponderant paragenesises of coexisting minerals of dunites and Cr-Pt-ores in mafic-ultramafic complexes of the Middle and Northern Urals a heterogeneous of dunites and Uralian type ores has been found. Placer ability of Pt-ores of the Uralian type towards to final stages of their formation (from chromite to pegmatite sub-type) is strongly decreasing. In general formation and trasformation of the Uralian type of ores has taken place in postmagmatic stage of their evolutuon.
