Évolution de la végétation et du climat pendant le miocène au Portugal

These work presents the quantitative and qualitative inventory and the stratigraphic distribution of fossil plants (spores, pollens, sterns, leaves and seeds) recognized the Miocene of the portuguese part of Tagus basin. For each lithostratigraphic unit, associations with ecological (paleoclimatic) meaning are defined. It was also possible to follow the evolution of the vegetation and the climate during the considered cronostratigraphic interval which includes most of the Miocene (Aquitanian to lower-middle Tortonian).

Chromian spinels in the basalts from the Lisbon volcanic complex (portugal) and their petrogenetic implications

Chromian spinels are common in the late Cretaceous alkali basalts of the Lisbon volcanic Complex in Portugal. They occur as unzoned inclusions in magnesian olivines of all basalt types and as large spectacularly zoned grains in the groundmass of porphyritic basalts. Microprobe analysis indicate complex cationic exchange in the groundmass zoned spinels due to simple peritectic reactions and in response to changing composition of the basalt liquid. The variation of cationic distribution in zoned chromian-Spinels, reflects very accurately the changing chemistry of the cooling silicate melt and the paragenetical relations of mineral oxides and silicates. Crystallization of initial chromian spinels occurred at T~1200°C and fO2~10-8.5 atm. earlier or contemporaneously with magnesian olivine. The titanomagnetite mantles of zoned chromian spinels crystallized at T~1200°C and much lower fO2.

Educação e Relações Interinstitucionais no Brasil e em Portugal

Este artigo visa discutir, sob enfoque comparativo, a descentralização da educação no Brasil e em Portugal a partir da década de 1990, isto com base na revisão da literatura pertinente e dos marcos jurídicos que vieram regulá-la, procurando problematizar as relações interinstitucionais que medeiam este processo, no Brasil, sob a ótica do regime de colaboração e, em Portugal, segundo as relações estabelecidas entre os poderes central e local. Como conclusão mais geral, constata que, apesar de o poder central vir difundindo o discurso da descentralização nestes países, já há algum tempo, tudo leva a crer que o plano da retórica não logrou ser efetivamente superado, pois entre avanços e recuos deste processo as tentativas vêm se constituindo em movimentos de alguma desconcentração de poderes, ainda marcados pela mesma lógica centralizadora, herança histórico-social, em ambos os casos, dos seus respectivos períodos ditatoriais, agora também sob a modulação de políticas econômicas neoliberalizantes.

Particularités de la microfaune (Foraminifère) à la limite Carixien/Domérien de quelques gisements de la region de Coimbra (Portugal)

The Middle Liassic outcrops of the Coimbra region (Portugal) show, at Carixian-Domerian boundary, an unusual high frequence of the Falsopalmula, morphogenus,that is generally well represented in the Lower Toarcian. The study of the Nodosaridea association shows that the massive presence of this morphogenus excludes the Lenticulina s. st. genus. These faunistic particularities should be ascribed to the environment and to the sedimentation pattern. The development of the Falsopalmula morphogenus should have been simultaneous to that of the pelitic sedimentation.

Microfacies studies of carbonate rocks from Jurassic outcrops in the north of Faro, Southern Portugal

The Middle and Upper Jurassique limestones investigated were sub-divided into nine microfacies (MF) types. The firsts four represent Bathonian sediments with shallow water characteristics typical for carbonate platforms. They are comparable with Wilson's facies zones 6 to 8. Reef and reef debris, near-shore clastic-dominated limestones are not present. These MF-types are reiterated several times without cyclicity. The vertical development of the differentiated facies units indicates a close interfingering. The microfacies data are typical of inter to shallow subtidal environments; both authigenous quartz and low faunal and floral diversity of several layers point to temporary restricted conditions. The occurrence of Dictyoconus cayeuxi LUCAS and Callovian ammonites from the above lying strata argue for a Bathonian age. The MF-types 5-9 (Oxfordian-Kimmeridgian) show completely different sedimentation conditions. Fully marine nearshore recifal limestones alternate with pelagic sediments formed at deeper shelf areas. The pelagic micritic limestones of Oxfordian age are characterized by allodapic intercalations whereas the Oxfordian/Kimmeridgian limestones with tuberolithic fabrics often show intensive silifications. Only initial patch reef growth-stages were reached during the development of the Oxfordian and Kimmeridgian shallow water limestones.

Origin and evolution of Upper Triassic to Miocene clay-mineral associations from the eastern Algarve of Portugal

XRD-analyses of pelitic deposits of Upper Jurassic to Miocene age occuring in the eastern Algarve (Portugal), give evidence of the occurrence of detrital clay minerals of continental origin as well as of conspicuous neoformations of marine provenance. The vertical succession of clay-mineral associations indicates the existence of three distinctive evolutionary cycles which are thought to reflect tectonically controlled transgressive-regressive events.

Découverte de «Plesiochelys», Chélonien marin-littoral, dans le Kimméridgien d’Alcobaça, Portugal

The presence of Craspedochelys (Plesiochelys s.l.) at Romão, Portugal, indicates that, in that country, the Thalassemydid dispersal began with the first occurrences of the group in Europe, in the late Kimmeridgian: communications existed between septentrional, atlantic and mesogean seas. The review of the family is considered.

Le Crétacé terminal de Beira Litoral, Portugal: remarques stratigraphiques et écologiques,étude complémentaire de Rosasia soutoi (Chelonii, Bothremydidae)

The synthetic study of the uppermost Cretaceous of the Beira Litoral (fauna, flora) confirms its upper Campanian-Maastrichtian age. It shows the presence of a tropical to subtropical climate in an area constituted by a low coastal plain only occasionally linked to the sea, saturated with fresh water and possessing accordingly, a predominantely freshwater fauna (Viso, Aveiro); this plain changed towards the interior into a drier more forested zone with a more abundant terrestrial fauna which includes mammals (Taveiro). A thorough study of the chelonian Rosasia, abundant on the coastal plain, was made possible thanks to the discovery of a skull: it demonstrates that the genus belongs to the family Bothremydidae, revalided here. The composition of this family is presented, its phylogenetic and paleobiogeographic relation with the other pleurodires are analyzed, and its diagnosis established. The family is constituted of three groups; Rosasia belongs to one of these, the Bothremys group.
