Lead isotopic model ages in galenas cluster around 121 ± 8 Ma in good agreement with previously suggested mesozoic age of this Pb-Zn mineralization estimated by apatite fission tracks in mylonitic wall-rocks. Isotopic composition of Mazarambroz mineralization suggests a high rock (metamorphic/granitic)/fluid interaction with minor participation of meteoric waters. These fluids circulated deeply along fragile cracks of the major shear zone of Toledo.spaEstudio de la composición isotópica (Pb-S-O) de las mineralizaciones Pb-Zn de Mazarambroz (Banda Milonítica de Toledo)journal articlehttp://www.sociedadgeologica.es/publicaciones_geogaceta.htmlopen access553.44(234.1)Pb-Zn mineralizationPb-S-O isotopesIberian Hercynian BeltPetrología
