• Resumen

  • It has been carried out the first whole rock Rb-Sr and Sm-Nd isotopic characterization of the Valencia del Ventoso plutonic complex, Ossa Morena Zone (Badajoz). The obtained emplacement age is 349±28 my, with an 87Sr/86Sr i of 0.70662 and eNd349 Ma = -1.6 y -5.6. This age includes this massif in the magmatic event developed after the devonian subduction regime, so after the ocean closure and the first and main deformational event related with the variscan orogen.
