RT Journal Article T1 El magmatismo alcalino jurásico del sector SE de la Cadena Ibérica: composición y estructura T1 The alkaline jurassic magmatísm In the SE area of Iberian Chain: composition and structure A1 Martínez González, R. M. A1 Lago San José, Marceliano A1 Valenzuela Ríos, J. I. A1 Vaquer Navarro, R. A1 Salas, Ramón AB Jurassic volcanic rocks are well exposed in the Sierra de Javalambre (Teruel)., This multiepisodic volcanism is mainly volcaniclastic , showing a large variety of fragmentation and emplacement mechanisms, and it is intercalated between carbonade rocks spanning from Pliensbachian through Bajocian. The mineral and chemical composition indicates a volcanism with alkaline affinity and little magmatic differentiation. From a geotectonic point of view, this volcanism corresponds to a late-volcanism within the postrift thermal subsidence (lower and middle Jurassic) that took place during the mesozoic development of the Iberian Basin (Iberian Chains ) PB Sociedad Geológica de España YR 1996 FD 1996 LK http://hdl.handle.net/10272/13158 UL http://hdl.handle.net/10272/13158 LA spa DS Repositorio Institucional de la Universidad de Huelva RD 30 may 2026
