(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 magmatic-related 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 pos thercynian hydrothermal activity covers a long span of timespaAtribución-NoComercial-SinDerivadas 3.0 Españahttp://creativecommons.org/licenses/by-nc-nd/3.0/es/Sm-Nd datingSpanish Central SystemF-Ba veinsjournal articleopen access
