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 carbonatic 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 Jberian Basin (lberian Chains).
