Abstract

Carbonate-hosted Pb-Zn deposits are common in the Yahyali region (Taurus Belt) with galena the most abundant sulfide mineral. The mean delta S-34 values for Goynuk, Celaldagi Desandre, Demircilik, Tekke, Havadan and Sucati 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 Pb-206/Pb-204, Pb-207/Pb-204 and Pb-208/Pb-204 measurements for the studied deposits were 18.968 +/- 0.005, 15.741 +/- 0.005 and 39.074 +/- 0.016 for Goynuk, 18.702 +/- 0.006, 15.715 +/- 0.006 and 38.883 +/- 0.021 for Celaldagi 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 Sucati. The sulfur isotope systematics imply that sulfur originated from a mixture of different sources for the Gobynuk and Sucati 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.
