Abstract: The Zn-Pb deposits occuring in Upper Permian-Triassic lower marbles and Bolkardağı marbles are strata-bound and epigenetic in character. Pyrite, sphalerite and galena are te main minerals within the hydrothermal sulfideore veins which are Upper Upper Paleocene-Lower Eocene in age.I The high average Sb and Ag concentration and high Zn/Pb ratio of the crude sulfide ores point to a hydrothermal origin and high formation temperature. High average Co, Ni, Ti, Cu and As concentration, high Co/Ni ratio and Co-NiMn relations of pyrite samples, high average Mns Cü and Fe concentration of sphalerite and low average Sb concentration of galena also support this conclusion.There is high correlation between Fe-Si, Ti-Fe, Cr-Fe, Si-Ca* Cr-Si, Cd-Zn, Ag-Pb and Sb-Cu element pairs of^sulfide ores and Co-Nit Co-Ti, Co-Ass Ni-Ti, Ni-As and Ti-As element pairs of concentrated pyrite samples.
