Abstract :Abstract. The Gürkuyu Sb mineralization is located in the western part of Anatolian tectonic belt, in southern part of İzmir-Ankara zone and in northern part of Menderes Massif. The mineralization located at west of the Koca hill in east of Gürkuyu village of Gediz (Kütahya-Turkey) has been characterized through the detailed examinations involving sulfur and oxygen isotope. Serpentinites of Dağardı melange and crystallized limestones of Budağan limestone were hydrothermally altered by hydrothermal solutions, come from fissures and fractures due to tectonic movement during the thrust of melange and occurred silicified zone. Gürkuyu Sb mineralization suggest that occurred in this silicified zone. In Gürkuyu mineralization, primary ore minerals are antimonite and pyrite, secondary ore minerals are senarmontite, valentinite, orpiment and realgar. Quartz and calcite are the most common gangue minerals. In Gürkuyu Sb mineralization, δ 34 S values of stibnite are ranged from 1.0 ‰ to 1.3 ‰. δ 18 O values of quartz are ranged is 15.8 ‰ in Gürkuyu mineralization. Sulfur and oxygen isotope values are similar to the values for magmatic rocks and to the values for fluids of magmatic origin.
