Emplazamiento de sills y diques del Pérmico superior en el Macizo de Cinco Villas (Pirineo Navarro)

Abstract

The emplacement of basaltic sills and dykes outcropping in the Cinco Villas Massif (Western Pyrenees), northwards of the North-pyrenean fault, was controled by the hercynian main-phase cleavage (dykes) and by the orientation of three small half-graben permian basins (sills), unconformably overlain by the Buntsandstein conglomerates. Both types of magmatism are cogenetic and coeval.
