New insights on the Hirnantian palynostratigraphy of the rio Ceira section, Buç...
Lopes, Gilda; Vaz, Nuno; Sequeira, A. J. D.; Piçarra, J. M.; Fernandes, Paulo; Pereira, ZéliaThe 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...
Resultados preliminares do registo isotópico de carbono orgânico (d13C org) do ...
Lopes, Gilda; Fernandes, Paulo; Goodhue, R.; Pereira, Zélia; Piçarra, J. M.A região de Barrancos apresenta uma das sessões mais complexas de Silúrico na zona da Ossa Morena.
The national inventory of geosites in Portugal
Brilha, J. B.; Alcalá, A.; Almeida, A.; Araújo, A.; Azerêdo, Ana; Azevedo, M. R.; Barriga, Fernando; Silveira, A. Brum; Cabral, J.; Cachão, M.During the last three years geoscientists of various institutions have developed a project aiming the setup of a geoconservation strategy in Portugal (Brilha, 2009). One of the main goals of the project was the establishment of an inventory of the most important Portuguese geosites, under the scientific point of view. In a near future, national authorities will consider this inventory as a technical support for...
Dados palinoestratigráficos preliminares do Gorstiano (Silúrico) da Formação de...
Lopes, Gilda; Vaz, Nuno; Sequeira, A. J. D.; Piçarra, J. M.; Fernandes, Paulo; Pereira, ZéliaNovos 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...
Palynomorphs from the Gorstian (Silurian) of the Sazes Formation (Buçaco Syncli...
Lopes, Gilda; Vaz, Nuno; Sequeira, A. J. D.; Piçarra, J. M.; Fernandes, Paulo; Pereira, ZéliaOccuring 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...
Silurian to Lower Devonian Palynomorphs from the Barrancos region, Ossa Morena ...
Lopes, Gilda; Pereira, Zélia; Fernandes, Paulo; Piçarra, J. M.; Oliveira, José TomásNew 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...

Bilha, J.; Andrade, C.; Azerêdo, Ana C.; Barriga, F.; Cachão, M.; Cunha, P. P.; Crispim, J. A.; Dantas, P.; Duarte, L. V.; Freitas, M.C.; Granja, M. H.This work constitutes the first contribution for the systematisation of the geological heritage knowledge in Portugal, following the international recomendations for the characterisation of geological heritage (IUGS, ProGEO). The application of the ProGEO methodology has resulted on the creation of fourteen frameworks with international relevance, established by consensus among the Portuguese geological communi...
