AB Combined lead, sulphur and oxygen isotopes have been analysed in ore (galena and sphalerite) andassociated (quartz, barite) minerals from the Mazarambroz Pb-Zn mineralization. Lead isotopic model agesin galenas cluster around 121 ± 8 Ma in good agreement with previously suggested mesozoic age of thisPb-Zn mineralization estimated by apatite fission tracks in mylonitic wall-rocks. Isotopic composition ofMazarambroz mineralization suggests a high rock (metamorphic/granitic)/fluid interaction with minorparticipation of meteoric waters. These fluids circulated deeply along fragile cracks of the major shear zoneof Toledo
