Caracterización geoquímica y encuadre geodinámico de las anfibolitas y eclogitas del manto de Ojén, Complejo Alpujárride, Cordilleras Béticas
Amphibolite bodies with eclogite relics are found interlayered between the Ojen nappe´s crustal rocks, below the Ronda peridotites of the Betic Cordilleras (southern Spain). We present a geochemical study of such amphibolites and retrogressed eclogites, from which it is possible to deduce a gabbroic...

| Resumo: | Amphibolite bodies with eclogite relics are found interlayered between the Ojen nappe´s crustal rocks, below the Ronda peridotites of the Betic Cordilleras (southern Spain). We present a geochemical study of such amphibolites and retrogressed eclogites, from which it is possible to deduce a gabbroic origin for their protoliths. We propose that their intrusion in the continental crust took place in a rift setting of Jurassic to Lower Cretaceous age. The recognition of this rifting event in the Alpujarride Complex places an additional constraint for Mesozoic reconstructions of the Western Mediterranean |
