Estratigrafia e interpretação paleogeográfica do Cenozóico continental do norte de Portugal

Palaeogeographic and tectono-sedimentary interpretation of northern Portugal, in which previous studies (geomorphology, lithostratigraphy, mineralogy, sedimentology, palaeontology, etc.) were considered, is here proposed. Cenozoic shows different features according to its morphotectonic setting in the eestern region (Trás-os-Montes) or near to the Atlantic coast (western region, Minho and Douro Litoral areas). Although in the eastern region the sedimentary record is considered late Neogene, in some places Paleogene (?) was identified. This oldest record, represented by alluvial deposits, was preserved from complete erosion because of its position inside Bragança-Vilariça-Manteigas fault zone grabens. Later sedimentary episodes (upper Tortonian-Zanclean ?), represented by two allostratigraphical units, were interpreted as proximal fluvial braided systems of an endorheic hydrographic network, draining to the Spanish Duero Basin (eastwards); nowadays, they still remained in tectonic depressions and incised-valleys. Later on, eastern sedimentation becomes scarcer because Atlantic fluvial systems (e.g. the pre-Douro), successively, captured previous endorheic drainages. The proximal reaches of the allostratigraphic unit considered Placencian is recorded in Mirandela (western Trás-os-Montes) but the following fluvial episode (Gelasian-early Pleistocene ?) was already documented in east Trás-os-Montes, preserved in high platforms and in tectonic depressions. Placencian and Quaternary sedimentary records in the western coastal zone, mainly represented by terraces, are located in the Minho, Lima, Alverães, Cávado and Ave large fluvial valleys and in the Oporto littoral platform. In conclusion, northern Portugal Tertiary sedimentary episodes were mainly controlled by tectonics, but later on (Placencian-Quaternary) also by eustasy.

O Caloviano do flanco norte do Guilhim (Algarve oriental): biostratigrafia e paleobiogeografia

Stratigraphical study of Telheiro and Cancela sections (northern slope of Guilhim hill) allowed its dating: these may be reported to the Lower Callovian, as ammonite associations typical of Rehmanni and Pictava horizons have been collected there. Hence Gracilis zone can be recognized in Algarve. Ammonites are also associated to Dinoflagellates. These microfossils have been found for the first time in the Callovian of Portugal. Callovian paleogeogtaphy is reapprised, and the limits between mesogean submediterranean and mediterranean provinces are more accurately recognized. Algarve belongs to the mediterranean province according to the typically mesogean character of the fauna where Phylloceratidae are dominant.

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.

Gestão Litoral: integração de estudos de percepção da paisagem e imagens digitais na definição da capacidade de carga de praias. O Troço Litoral S. Torpes - Ilha do Pessegueiro

O litoral, espaço geográfico de interface entre o meio marinho e terrestre, reúne múltiplos recursos que têm vindo a ser explorados ao longo dos tempos de uma forma cada vez mais intensa. A crescente ocupação humana das áreas litorais nos últimos 50 anos é disso um claro exemplo, chamando cada vez mais a atenção de entidades e especialistas de vários domínios científicos, para a necessidade de disciplinar e ordenar a exploração dos sistemas litorais. As praias, enquanto parte integrante destes sistemas, não fogem à situação descrita, uma vez que o turismo, entendido como uma das principais indústrias do final do século XX (Nordstrom, 2000), as elege como espaço privilegiado de destino, promovendo o desenvolvimento dos aglomerados adjacentes que suportam todas as actividades complementares ao turismo balnear. As áreas litorais em geral e as praias em particular, são excelentes exemplos de pontos de suporte da actividade turística, muitas vezes, a principal fonte de rendimentos para alguns países, como se pode depreender das palavras de Clark; “Good beaches are worth bilions of tourist dollars. Degraded beaches are worth little” (1995: 17). Assim, a praia pode ser considerada como um factor produtivo limitante do crescimento de um destino turístico, que tem de ser respeitado, para não existir uma degradação de condições que ponha em causa as suas características atractivas, geradoras de toda a riqueza. Mas a degradação das praias é, apenas, um entre vários impactos negativos provocados pela exploração massiva dos sistemas litorais e daí o seu estudo e preservação serem considerados cada vez mais cruciais em processos de desenvolvimento de efectiva sustentabilidade (Pesme, 1997).

Depósitos continentais e marinhos na plataforma litoral da região do Porto. Importância da tectónica na sua organização espacial

One of the most common characteristics of Portuguese littoral is the existence of a planed surface (the so-called "littoral platform"), situated at different altitudes and bordered from the inland by a straight relief, strongly contrasting with that planed surface. This one is generally covered with several outcrops of the so-called Plio-Pleistocene deposits. Till the eighties this platform has been interpreted as stable staircase of old marine levels, registering in a passive way the eustatic variations. The rigid step bordering it easterly should be a fossil cliff. However, our study has proved that many of these deposits have a continental origin. These continental deposits have fluvial or alluvial fan facies and they are lying above 40 meters. Marine deposits seem to be quite rare and they only occupy a small western area, beneath the altitude of 40 meters and developing into three different marine levels. There is a rigid step between the two kinds of deposits. We think that the clear geometric separation between these deposits together with this rigid step, indicates a tectonic origin. It seems that the sea must have touched only the western part of this surface, when neotectonic movements lowered it down. There are more evidences for neotectonic movements: a) there are faults (mainly inverse faults) affecting the higher deposits of this littoral platform; b) the same marine level seems to appear at different altitudes, developing an irregular pattern with a general trend dipping from the North to the South.
