dc.description.abstractTwo families ofdykes are distinguished in the Ta/iga-Barcarrota area with directions NW-SE and E-W (the younger one). Chemical affinity is tholeiitic shifting from 01+Hy normative in the first to Q+Hy normative in the second. A 1<-Ar whole rock age gives 250±5 M. A. (i.e. Upper Permian). Evolution by olivine and minor pyroxene fractionation is proposed. These dykes likely represent an earlier post Hercynian ensialic extensional magmatism which should be taken into a account in any geodynamic model of post Hercynian evolution of the Iberian Peninsulaes_ES
