Abstract
The mineralogical and geochemical patterns of platinum-bearing vein–impregnated and massive chromitite from dunite of the Svetloborsky, Veresovoborsky, and Kamenushensky clinopyroxenite–dunite massifs (Middle Urals) are reported. Platinum is characterized by an extremely uneven distribution in chromitite and is concentrated in the form of Pt–Fe intermetallic compounds. The structural and textural patterns of chromitite from these massifs, the PGE distribution in it, and the composition of chrome spinels are similar to those in well-studied chromitite from the zoned clinopyroxenite–dunite massifs of the Urals (Nizhny Tagil) and Koryakia (Gal’moenansky).
