The Kocadal base and precious
metal mineralizations are located in the southwest of Gümüşhane province of the
eastern Pontide orogenic belt. In the vicinity of the Kocadal mineralization,
Gümüşhane granite, lithologies of the Hamurkesen, Berdiga, and Mescitli
formations, dacite porphyry and andesite porphyry are present with abundant
alluvium. Based on geological, mineralogical, and geochemical features, three
mineralization styles have been recognized at the Kocadal area: (i)
Mineralizations around Batarya tepe include (ia) Zn mineralization within the
conglomerates and sandstones of the Hamurkesen formation and (ib) Zn-Pb-Ag-(Au)
mineralization associated with dacite prophyry, (ii) Au mineralization, which
occurs to the southwestern of Batarya tepe, and (iii) Cu mineralizations
related to quartz veins and veinlets at Gözelerin Dere. Mineralized gravels
within the conglomerates contains mainly sphalerite and pyrite, whereas
hydrothermal mineralizations associated with porphyritic dacite comprise pyrite
and sphalerite, with minor galena, chalcopyrite, pyrrhotite, arsenopyrite, marcasite,
fahlerz, pyrargyrite, and proustite. Alteration patterns of hydrothermal
mineralization in the field, from older to younger, are classified as: (i)
tremolite-actinolite±garnet, (ii) quartz-sericite-chlorite, and (iii)
carbonate-quartz. Mineralized gravels within the conglomerates contains mainly
sphalerite and pyrite, whereas pyrite, chalcopyrite, and galena are common in
quartz veins at Gözelerin Dere. Geostatistical studies based on the results of
geochemical analysis of core samples reveal the presence of the distinct
element associations for the different styles of mineralizations.
