In the Eastern Pontide Region of northeastern Turkey, volcanogenic Cu-Zn-Pb deposits of the Kuroko type are widespread within the dacitic series of the Liassic-Eocene volcano-sedimentary succession. Sulfide mineralization within the studied deposits shows four different depositional styles: disseminated ore; polymetallic stockwork ores; polymetallic massive ores; and disseminated pyrite in the hanging-wall tuff units. Only the stockwork and massive ores are economically important, and usually one or the other dominates in each ore body.
