Abstract

The geochemistry of chromium spinel and platinum group elements (PGE) provides significant information about conditions in the mantle during the emplacement and genesis of ophiolitic complexes. The Elekdag ophiolite is a greenschist to amphibolite facies ophiolite that was emplaced onto the Sakarya Zone, in the central part of the Pontides of northern Turkey. NW-SE trending Elekdag ophiolite hosts small scale chromitite occurrences in serpentinized harzburgite and dunite, and have maximum resource of several thousands t Cr2O3.
