A new type of Pt-Pd mineralization has been established in the chrome ores of the Main Saranovskoye deposit. The palladium content in the studied chromitites reaches 7.7 ppm, platinum – 0.5 ppm. The minerals are represented by tellurides, arsenides and arsenido-antimonides Pt and Pd – kotulskite, temagamite, atheneite, sperrilite, isomertiite. Chromitites have a specific spotted structure and occur in the form of lenticular separations among the massive medium- and high grade ores of the eastern and western ore bodies of the deposit. As in other stratiform complexes, the formation of Pt-Pd mineralization is associated with the crystallization of residual melt, which penetrated into already crystallized chrome ores. The structural and textural features of chromitites suggest that the localization of platinum-palladium mineralization occurred under the influence of tectonic processes.
