%X 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.
