Sulfur and lead isotope investigations of the carbonate-hosted Pb-Zn deposits in the Yahyali region, Kayseri, Southern Turkey

Abstract

Carbonate-hosted Pb-Zn deposits are common in the Yahyali region (Taurus Belt) with galena the most abundant sulfide mineral. The mean ?34S values for Göynük, Celalda?i Desandre, Demircilik. Tekke, Havadan and Suçati deposits were +0.2±0.5, +9.3±0.8, +10.7±1.3, +10.8±1.3, +11.5±2.4, -4.2±0.4‰. respectively. The mean 206Pb/204Pb, 207Pb/204Pb and 208Pb/204Pb measurements for the studied deposits were 18.968±0.005, 15.741±0.005 and 39.074±0.016 for Göynük 18.702±0.006. 15.715±0.006 and 38.883±0.021 for Celalda?i Desandre, 18.618±0.020, 15.727±0.008 and 38.852±0.032 for Demircilik. 18.808±0.017. 15.751±0.028 and 38.983±0.166 for Suçati. The sulfur isotope systematics imply that sulfur originated from a mixture of different sources for the Göynük and Suçati deposits, but was probably derived from seawater for the others. The distribution of lead isotopic ratios had a well-defined cluster for each deposit but no linear trend defining enrichment in radiogenic lead. Copyright © TÜBİTAK.
