dc.description.abstractThe Lahanos volcanogenic massive sulfide (VMS) deposit is situated in the westernpart of the eastern Pontide tectonic belt. The deposit is hosted predominantly by a late Cretaceous felsic volcanic complex and is mined mainly for copper and zinc. The deposit is essentially stratabound, with characteristics of both Cu-Zn-and Cu-Zn-Pb-type stratiform VMS deposits. The deposit consists mainly of yellov ore (oko) and a zone that can be considered as semi-blackore. Ore mineralization occurs mainly as massive ore, and to lesser extent as disseminated andstochvork ore. Major ore minerals include pyrite, chalcopyrite, sphalerite, galena, tetrahedrite/tennantite, bornite, and minor to trace covellite, marcasite, chalcocite, and digenite. Gangue minerals are chiefly auartz and barite with minor calcite and dolomite. The deposit has aparagenetic seguence of pyrite (I, II) - chalcopyrite (I) sphalerite -galena tetrahedrite/tennantite digenite chalcosite pyrite (III) - chalcopyrite (II) bornite covellite. A great variety of intimate intergrowth ore textures including replacement, colloform, disseminated, and fragmental textures prevail throughout the deposit. The fine-grained nature of the Lahanos ore presents difficulties in beneficiation. Sphalerite, as in other VMS deposits of the region, is notably Fe-poor (< 0. 7 wt. %).
