Abstract
Une microflore d'âge Barrémienne ététrouvée dans les faciès terrigènes (Weald) du Crétacé inférieur du Nord de la Province de Valencia (Espagne), que manquaient une datation précise par l'absence des fossiles. La microflore de Villar del Arzobispo appartient indisputablement au Barrémien-Aptien, mais l'importance numérique des formes dérivés du Jurassique, la grande variété de formes de Cicatricosisporites et la rareté de pollen d'Angiospermes indiquent un âge Barrémien probable.
Cette découverte nous a permis établir les relations stratigraphiques eńtre ces faciès térrigénes de Villar del Arzobispo et le Weald daté dans autres parts de la Chaîne Ibérique, ainsi que donner une interprétation chronostratigraphique aux différents unités lithostratigraphiques du Crétacé inférieur de cette région.
A Barremian microflora is recorded in the terrigenous facies (Weald) of the Lower Cretaceous in the northern region of the Province of Valencia (Spain), these beds have been poorly dated up to now due to the absence of fossils. The Villar del Arzobispo microflora correspond unquestionably to the Barremian-Aptien period, but the numerical importance of derived forms from the Jurassic, the remarkable variety of forms of Cicatricosisporites, and the rareness of pollen of Angiosperms, indicate a Barremian age to be more likely. This discovery permits us to establish the stratigraphical relationship of this terrigenousfacies of Villar del Arzobispo with the dated “Weald” of other areas of the Iberian Chain and to give a complete chrono-stratigraphical interpretation to the different litho-stratigraphical units that constitute the Lower Cretaceous of this region.
