A1 Lago San José, Marceliano A1 García Bellés, J. A1 Arranz, Enrique AB The Upper Permian magmatism in the Cinco Villas Massif (Navarra, Western Pyrenees), is represented in two kinds ofcogenetic products: a) three reduced basins, with strongly altered basaltic sills and b) dolerite dykes, with two types (augite-rich and plagioclase rich), outcropping in Yanci-Aranaz area. The study of the chemical composition ofthe piroxenes indicates a sub-alkaline to alkaline affinity for thjs magmatism PB Sociedad Geológica de España YR 1998 FD 1998 LK http://hdl.handle.net/10272/18064 UL http://hdl.handle.net/10272/18064 LA spa DS Repositorio Institucional de la Universidad de Huelva RD 31 may 2026
