The Pb-Zn-Cu mineralization of Kadikalesi occurs in the Bodrum peninsula in SW Turkey, at the western end of the Taurides. This mineralization belongs either to the Taurus mineralized belt or to the younger mineralization of the Aegean province. The geology of the mineralized zone is described and the mineralization observed classed according to its mode of occurrence. Each type thus defined is studied and the paragenetic relationships among the different mineral phases are determined. Pyrite, sphalerite, tetrahedrite-tennantite, galena, bournonite, are the main primary minerals with chalcopyrite and hematite occurring as accessories, and boulangerite being quite rare. Covellite, pyrolusite, malachite-azurite and iron hydroxides are of secondary origin. In addition to the microscope studies, the reflectivity and microhardness have been determined on the primary phases, the compositions of which have either been verified or determined by micro- probe. On the basis of the data obtained, it is thought that this hydrothermal mineralization, which is limited to calcareous and volcanic rocks, were formed in mesothermic conditions. The genesis, age relationships and magmatic setting of this mineralization suggest that it belongs to the Miocene Aegean metallogenic province.
