Galindo Francisco, Mª del CarmenDarbishyre, D.P.F.Tornos Arroyo, FernandoCasquet, César2023-06-202023-06-2019930213-683Xhttps://hdl.handle.net/20.500.14352/56935Sm-Nd dating of F-Ba (Pb-Zn) veins enclosed in adamellites of the Spanish Central System suggests an age of 752±25 M.a. (Late jurassic) for this hydrothermal stage. This age supports an unconformity-related origin for this style of mineralization and excludes any genetic relationship with a magmaticrelated hydrothermal activity related to the enclosing granites. It is consistent with K-Ar and Rb-Sr dating of other hydrothermal events in the Sierra de Guadarrama and strengthens the hypothesis that the late and posthercynian hydrothermal activity covers a long span of time.spajournal articlehttp://www.sociedadgeologica.es/publicaciones_geogaceta.htmlopen access550.93(234.1)Sm-Nd datingSpanish Central SystemF-Ba veinsGeoquímica2503 Geoquímica
