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  plasmamass-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
