55 galena samples from 18 deposits. Volcanite-hosted deposits have a less radiogenic lead isotope composition than sediment-hosted deposits, while galena in quartz segregations and crack fillings shows the most pronounced radiogenic lead isotope composition. Application of the plumbotectonic model to the lead isotope data for the stratiform deposits suggests that the volcanite-hosted deposits show the most significant influence of a mantle-related source.--Modified journal abstract.
