Abstract

Kure region is located in western part of the Pontide tectonic belt. The oldest rocks around Kure are Paleozoic metamorphic rocks constituting “Rhodope-Pontide” continent. Liassic-pre Liassic ophiolites and basaltic volcanics, which form Paleotethys Ocean Floor are situated on “Rhodope-Pontide” continent as Paleotethys Ocean Floor residuals. Massive sulfide deposits in Kure Region are closely associated with pre Liassic – Liassic basaltic volcanics and intercalating black shale. These deposits are considered to have formed during hydrothermal mineralization processes when basaltic volcanism had stopped and defined as “Black Smoker” today. Massive sulfide bodies in Magaradoruk copper deposits are lens shaped. Although ore lenses take place sometimes in basalts and black shales, they are generally located on basalts and are covered by black shales. In Kure region, fold structures are intensely observed, and Magaradoruk deposit is located on western flank of an overturned anticline. Magaradoruk deposit is formed by several small and a big ore body and by less developed, underlying stockwork disseminated ore. The big ore body is 600 m long, 250 m wide and nearly 40 m thick. As main ore minerals; pyrite and chalcopyrite are observed. In few amounts; marcasite, magnetite, hematite, sphalerite, covelline, neo-digenite, malachite, azurite, fahlers are seen. In fewer amounts; bravoite, lineiite (karolite), limonite, and in trace amounts; chromite, rutile anatase, chalcosine, cuprite, tenorite, pyrrhotite, valleriite, bornite, galenite, native copper and native gold are observed. Main gangue minerals are; quartz, siderite-ankerite calcite, dolomite and chlorite. Magaradoruk massive sulfide deposit within basaltic rocks resembles to Siirt Madenkoy, Ergani massive sulfide deposits, to “Cyprus” type massive sulfide deposits and modern Cyprus type massive sulfide deposits in terms of mineral contents; and to Ergani Mihrapdagi, Papuke, Pakotai and Parakoa deposits in terms of cover rocks, which are Cyprus type massive sulfide deposits, in New Zealand
