The study of the chemical composition ofthe piroxenes indicates a sub-alkaline to alkaline affinity for thjs magmatism}, publisher = {Sociedad Geológica de España}, title = {Petrología de diques doleríticos y basaltos, Pérmico superior, en el Macizo de Cinco Villas (Pirineo Navarro)}, title = {Petrology of Upper Permian doleritic dykes and basalts, in the Cinco Villas Massif (Navarra, Western Pyrenees)}, author = {Lasheras Adot, E. and Lago San José, Marceliano and García Bellés, J. and Arranz, Enrique}, }
