Nuevos datos petrológicos, geocronología (Rb-Sr) y geoquímica isotópica (Sr, Nd) del plutón de Ventosilla (Sierra de Guadarrama, Sistema Central Español)
Whole rock Rb-Sr Isotopic analyses on granites from Ventosilla pluton yield an age of 346 ± 63 Ma, and intercept at 0.708688 ± 0.00094. This age increases the time-span of the Hercynian plutonism in the area up to 70 Ma. The presence of a complex residual mineralogy and their Sr and Nd isotopic sign...

| Summary: | Whole rock Rb-Sr Isotopic analyses on granites from Ventosilla pluton yield an age of 346 ± 63 Ma, and intercept at 0.708688 ± 0.00094. This age increases the time-span of the Hercynian plutonism in the area up to 70 Ma. The presence of a complex residual mineralogy and their Sr and Nd isotopic signatures, overlapping the previous isotopic data on peraluminous granites from the Spanish Central.System, suggest melting of mainly crustal sources for the origin of this pluton. |
