Abstract: Çolaklı-Elazığ mineralizations occur as vein type fillings in the fracture zones of diorite rocks of Coniacian-Camp onionElazığ magmatites. The veins strike N10-6Ö* W and dip vertically. They extend between 250-800 meters and their thicknessesvary between 0.5-3.5 meters on the surface. The ore mineral assemblage of the veins are galena, freibergite, pyrite, cubanite,chalcopyrite, tetralxedrite, barytine and secondaiy minerals derived there. The ore is massive or disseminated within thecarbonate minerals and quartz. The chemical analysis give high Pb, Ag, Zn andSb values. Ag takes places in the structure offreibergite which itself occurs always as enclosed in galena This is well demonstrated by high A g-Pb, Cu-Sb and A g-Sbvalues (r=0.82, r=0.73 and r=0.86 resprectively).Çolaklı mineralization appears to be fowned by the late phase magmatic solutions originated from granitic intrusionswhich followed the deformation and fractiuing of the dioritic rocks. This model is supported by the presence of aplite andquartz- filled veins within the ore veins.
