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}, publisher = {Sociedad Geológica de España}, title = {Estudio de la composición isotópica (Pb-S-O) de las mineralizaciones Pb-Zn de Mazarambroz (Banda Milonítica de Toledo)}, title = {Pb-S-O isotopic study of the Mazarambroz Pb-Zn mineralization (Toledo Shear Zone)}, author = {Villaseca, Carlos and López García, José Ángel and Barbero, Luis}, }
