Datación por el método Sm-Nd del filón con F-Ba (Pb-Zn) de la mina San Eusebio (Sierra de Guadarrama, España)
Sm-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 magmatic...

| Sumario: | Sm-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. |
