Palynologie du Permien et du Trias dans le Centre de la Péninsule Ibérique

Palinological data from the Carbonatic and siliciclastic sediments in Central System and Iberian Ranges has allowed us to make some age-dating for most of sediments unconformably overlying the lower Paleozoic metamorphic basement. Twelve palynological assemblages have been identified. They range in age from early Permian (Autunian) to late Triassic (Carnian). Early Permian consists mainly of grey-black sediments filling small isolated half graben basins. Saxonian facies unconformably overly Autunian or Early Paleozoic rocks. Paleontological data for Saxonian facies point to a middle to late Permian age. The overlying Triassic rocks (upper Buntsandstein, Muschelkalk and Keuper) contain several palynological assemblages. Anisian, Anisian-Ladinian, Ladinian s.l, Late Ladinian and Carnian. Some ages have been also compared with ammonoids and conodonts dating in some areas.Peer reviewe
