RT Journal Article T1 Nuevos datos geocronológicos y geoquímicos de las manifestaciones volcánicas de Picasent y Cofrentes (Valencia) T1 New geochronological and geochemical insight on the volcanic occurrences of Picasent and Cofrentes (Valencia) A1 Ancochea, Eumenio A1 Huertas, María José AB 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 PB Sociedad Geológica de España YR 2002 FD 2002 LK http://hdl.handle.net/10272/9364 UL http://hdl.handle.net/10272/9364 LA spa DS Repositorio Institucional de la Universidad de Huelva RD 13 jul 2026
