AB The Almadén district constitutes the largest and probably the most intriguing mercury concentration inthe world. This paper reports the first lead isotope compositions of cinnabar from the district. Wholesamples and stepwise leaching cinnabar aliquots display relatively homogeneous isotopic compositions(206Pb/204Pb = 18.112 - 18.460; 207Pb/204Pb = 15.635 - 15.705; 208Pb/204Pb = 38.531 - 38.826). Takentogether with Jébrak et al. (2002) pyrite lead isotope results, the new cinnabar isotopic data defines asteep array trend on the 207Pb/204Pb - 206Pb/204Pb diagram, suggesting a mixed contribution from bothancient upper continental crust and (enriched mantle derived) magmatic sources for the ores of the AlmadénHg deposits
