Hakkari Zn-Pb province is a newly discovered metallogenic province of the Neotethyan belt. The deposits of this province occur within Middle-Upper Triassic-Jurassic carbonates. Important deposits are Meskantepe, Karakaya and Üzümcü. More than one ore zone is observed parallel to each other along the province. The thickness of each ore zone varies from a cm scale to a few m (0.1 to 6 m). The primary ore was mostly in-situ oxidized and “non-sulphide” zinc deposits was developed. However, primary sulphidic ore lenses have been observed within non-sulphide ore zones. Non-sulphide ore zones consist of smithsonite, hemimorphite, zincite/hydrozincite, goethite, hematite, lepidocrocite, cerussite and anglesite. Primary ore include pyrite, marcasite, sphalerite and galena. This study details the sulphur and lead isotope characteristics of the province. The average δ34SCDTvalue of sphalerite, pyrite and galena (total 39 samples) of Hakkari province is 1.74‰ (from-3.43‰ to 8.78‰) indicating a large and relatively homogeneous sulphur source. Sulphur isotope data indicate that the source of sulphur most probably was marine sulphates and that TSR was effective in sulphur reduction processes. The lead isotope ratios of galena (206Pb/204Pb between 18.325 and 18.756;207Pb/204Pb between 15.579 and 15.700; and208Pb/204Pb between 38.421 and 39.034) of the Hakkari Zn-Pb province are slightly heterogeneous, relatively radiogenic and fall close to upper crustal growth curves, like SEDEX deposits globally rather than MVT deposits.
