El enjambre filoniano básico intrusivo en el Complejo plutónico Táliga-Barcarrota (Ossa-Morena, Badajoz)

Two families of dykes are distinguished in the Taliga-Barcarrota area with directions NW-SE and E-W (the younger one). Chemical affinity is tholeiitic shifting from Ol+Hy normative in the first to Q+Hy normative in the second. A K-Ar whole rock age gives 250±5 M. A. (i.e. Upper Permian). Evolution b...
