The Lower Palaeozoic successions of Portugal are well represented in the Central Iberian Zone (Cll), one of the main tectonostratigraphic domains of the Iberian Massif. Located in the CIZ, the Bu<;aco Syncline presents one of its most complete Palaeozoic sequences. With a NW-SE orientation, the Lower Palaeozoic lithostratigraphic succession, includes several Ordovician units that ranges from the Lower Ordovicia...
A região de Barrancos apresenta uma das sessões mais complexas de Silúrico na zona da Ossa Morena.
Novos dados bioestratigráficos foram obtidos na sucessão estratigráfica do Paleozóico Inferior da região do Buçaco. A Formação de Sazes (Silúrico) está a ser estudada ao nível palinológico (miosporos e quitinozoários) e de macrofósseis (graptólitos), com o intuito de rever e complementar dados bioestratigráficos anteriormente descritos. Com base nos dados palinológicos, parte da Fm. de Sazes foi datada co...
Occuring in a complex syncline that extends from Buçaco to Penedo de Góis, the studied area is located in the Central Iberian Zone of the Iberian Massif. In this region outcrops a well-preserved and complete stratigraphic succession of Lower Paleozoic age. At the top of the Buçaco Syncline stratigraphic succession, the Silurian Sazes Formation (Paris, 1981), is currently being studied at a palynological (miospo...
New miospore results were obtained from the Palaeozoic stratigraphic succession present in the Barrancos region, Portugal. The studied formations comprise the Silurian carbonaceous shales intercalated with cherts and rare lenticular carbonates of the Xistos com Nódulos Formation, as well as, the dark shales that alternates with thin psammit beds of Late Silurian to Early Devonian age from the Xistos Raiados For...
