The Eastern Black Sea Region of Turkey contains over 400 massive (Kuroko type) and vein type Cu-Pb-Zn deposits. The Inler Yaylasi lead-zinc deposits are typical examples of the vein type and have been economically mined for 15 years. Three ore veins were identified along E-W trending fault zones, hosted by extensively altered, Upper Cretaceous volcano-sedimentary rocks. A Tertiary granitoid intrusion occurs near the area of mineralization. The ore veins contain sphalerite, galena and minor amounts of pyrite, chalcopyrite, fahlore, chalcocite and covellite as ore minerals, with quartz and calcite as gangue minerals.
