Abstract
Lead-zinc deposits in the Meixian area, Fujian Province, China, consist mainly of stratiform sphalerite-galena ores in the upper Proterozoic metamorphic rocks. δ34S values of sulfide minerals (sphalerite, galena, pyrrhotite, and pyrite) range from −3.3 to +4.2‰. These sulfur isotope values indicate that the sulfur was mainly derived from an igneous source rather than from a reduction of seawater sulfate. Lead isotope compositions of the ore minerals show relatively high207Pb/206Pb values, suggesting the contribution of crustal lead with high radiogenic components.
