Summary:The Tyndrum Pb-Zn veins, hosted by Late Proterozoic quartzites, are probably of Tournaisian age (360 m.y.). Twelve galenas have delta 34S values ranging from +3.55 to +6.38per mille (excluding one value of +11.21per mille from a large but nearly barren quartz vein). Other sulphides are enriched or depleted in 34S in the sense expected for isotopic equilibrium although there is no evidence for isotopic equilibrium between the vein minerals. The sulphide sulphur source was probably in the Dalradian metasediments where disseminated pyrite averages +6per mille. Baryte had delta 34S values averaging 14per mille and was therefore not in isotopic equilibrium with sulphides: a continental groundwater source is most likely. [L.G.L.]
