RT Journal Article T1 Datación por el método Sm-Nd del filón con F-Ba (Pb-Zn) de lamina San Eusebio (Sierra de Guadarrama, España) A1 Galindo Francisco, Mª del Carmen A1 Darbishyre, D.P.F. A1 Tornos Arroyo, Fernando A1 Casquet, César AB Sm-Nd dating of F-Ba (Pb-Zn) veins enclosed in adamellites of the Spanish Central System suggests anage of 752±25 M.a. (Late jurassic) for this hydrothermal stage. This age supports an unconformity-relatedorigin for this style of mineralization and excludes any genetic relationship with a magmaticrelatedhydrothermal activity related to the enclosing granites. It is consistent with K-Ar and Rb-Srdating of other hydrothermal events in the Sierra de Guadarrama and strengthens the hypothesis thatthe late and posthercynian hydrothermal activity covers a long span of time.
