Özet

As nonferrous metals, lead zinc is the most widely used ore after aluminum and copper. Considering the increasing demands in industry, it is understood that a sustainable mine supply is necessary to meet the Pb-Zn. In this context, the geochemical characteristics of the Erva lead zinc deposit in Yahyali (Kayseri) district were tried to be revealed. The study area, Yahyali district, is located in the Southeast of the Central Anatolia Region. The geological unit in which the Erva is located is the Yahyali Munzur Nappe, which tectonically overlies the Feke sequence. In this study, XRF (X Ray Fluorescence Spectrometry) and XRD (X-Ray Diffraction Analysis) geochemical analyzes were carried out in order to understand the lead zinc ore metal source. As a result of the XRF analysis, the average ZnO and PbO grade values (in %) were found as follows: 7.85 and 4.33. According to the XRD results, the mineral paragenesis that forms the ore is as follows: Galena, Cerussite, Smithsonite, Quartz, Gypsum, Hematite, Goethite, Anglesite, Kaolinite, Montmorillonite. Mineralization occurring in the region where geologically young formation aged rocks are present is not seen among large karst cavities. Instead, mineralization in the form of geological fillings is observed in the capillary cracks of the carbonates within the Yahyali Munzur Nappe.
