Özet

Magnetite is a common mineral in paragenesis in many mineral deposits, and it is recognized that it covers the conditions of the environment in which it is formed due to its physico-chemical properties. For this reason, chemical compositions of magnetites are used in researches on the origin and formation of ore deposits. Gökçedoğan Cu-Zn massive sulfide deposit (VMS) in the Central Pontides is a syngenetic stratiform deposit observed in metamorphic rocks. The ore paragenesis contains pyrite, chalcopyrite, sphalerite, magnetite, hematite, covellite, malachite, and goethite respectively. Because of its physicochemical properties, in-situ laser-ablation inductively coupled plasma mass-spectrometry (LA-ICP-MS) analysis of magnetite in the ore zone was performed and a new perspective was promoted to the deposit. From analysis Fe is between 72.06-73.39% and O is between 20.78-21.15% respectively. V content is approximately higher than the other trace elements. Analyzes were checked out in both Cu/(Si+Ca)-Al(Zn+Ca) and Cu/Ca-Al(Si+Zn+Ca) diagrams and it was decided that they exhibit similar distributions to VMS deposits in the world. In the spider diagram drew up, it has been showed that Gökçedoğan VMS deposit is close to Besshi Type Windy Craggy deposit with its high Si values.
