Abstract

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 c1early distinctive. The Picasent occurrence consists of alkaline
rocks which have been dated at 8 Ma. These rocks constitute an onland 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 CampQs de Calatrava volcanic area.
