• Resumen

  • Trace elements of barite veins of the hercynian basement of the Unidad de Herrera (Eastern Iberian Chain) have been analysed. The results show the influence of the basement materials on the mineralizing fluids. The barite Sr-content shows the deposit evolution. Barite Sr87/Sr86 ratio ranges from 0.713 to 0.717, far from the seawater or evaporite values; this points to a crustal sources for the barite veins Sr, more likely from sedimentary rocks of the hercynian basement.
