| Sumario: | The volcanic region of eastern Spain is badly known, mainly because of lack of subaerial exposures, which are restricted to the Cofrentes and Picasent outcrops. Moreover, these volcanic occurrences show somewhat compositional differences and their ages are clearly distinctive. The Picasent occurrence consists of alkaline rocks which have been dated at 8 Ma. These rocks constitute an on land representation of the volcanic activity developed in the Valencia Gulf during the Miocene. The Cofrentes occurrence is made up of ultra-alkaline volcanic rocks, ranging 1 -2 Ma in age, thus evidencing a second phase of volcanic activity in eastern Spain that can be related to the Campos de Calatrava volcanic area |
