• Resumen

  • High-grade metamorphic xenoliths occur in the Denuy-Ribera magmatism (Huesca, Central Pyrenees) representing materials from deep levels of the hercynian crust in the Pyrenees. These rocks, divided into two compositional groups —felsic and mafic compositions— > have been metamorphosed to granulite facies, as shown by their mineral assemblages and compositions.

    This study offers a complete petrological, textural and mineralogical characterization of posthercynian compositions in the lower Pyrenean crust.
