Özet

Three podiform-type deposits, namely Kahramanmaras, Ortaca and Kop, have been investigated for their chromite composition, Platinum-group elements geochemistry and mineralogy. The investigated chromitites are associated with the mantle sequence of ophiolites are remnants of Tethys Oceanic crust. Based on the composition of chromite, the analyzed chromites can be classified as refractory and metallurgical. As typical for mantle-hosted ophiolitic chromitite, the PGE contents are low (less than 541 ppb) with an enrichment in Os-Ir-Ru. The platinum group minerals (PGM) form small grains (generally less than 10 mu m in size) and most of them are Os-Ir-Ru phases, rarely accompanied by Pt and Pd minerals. These observations indicate that the investigated Turkish chromitites represent only a future potential target for PGE recovery.
