M. A1 Lago San José, Marceliano A1 Vaquer Navarro, R. A1 Valenzuela Ríos, J. I. A1 Arranz, Enrique AB The study of olivine, plagioclase, clinopyroxene and opaque minerals from volcanic rocks, which are included in volcaniclastic deposits o f pre -m id d le Bajocian age from the Sierra o f Javalambre (Iberian Chain, Teruel), shows that this volcanism has an alkaline affinity. The compositional trend of this alkaline magma is recognized by studying the clinopyroxene composition PB Sociedad Geológica de España YR 1995 FD 1995 LK http://hdl.handle.net/10272/13371 UL http://hdl.handle.net/10272/13371 LA spa DS Repositorio Institucional de la Universidad de Huelva RD 14 jul 2026
