Reinterpretation de l'Histoire Stratigraphique et Tectonique de la Structure de Serra de El-Rei (Portugal)

Les travaux faits sur le terrain et les interprétations cartographiques de ces dernières années, montrant la pertinence des observations de Paul Choffat au siècle dernier, permettent de préciser l'échelle stratigraphique et de mieux distinguer les phases de l'histoire tectonique de la structure de Serra de EI-Rei. En attendant la publication d'une cartographie très détaillée mettant en évidence le détail des déformations tectoniques, il faut souligner la dissymétrie des deux flancs de cette structure ainsi que le rôle de certaines failles transverses. Sur son flanc nord, la série liasique, allant des dolomies du Lias inférieur au Toarcien inférieur ou moyen, est recouverte stratigraphiquement et en légère discordance par le "Lusitanien" qui remanie à sa base des éléments du Toarcien inférieur ou moyen. Sur son flanc sud, dans la partie centrale, la série stratigraphique liasique est comparable à celle de l'autre flanc, mais les dépôts du Toarcien, plus complets, sont affectés au cours de la zone à Meneghinii par des perturbations synsédimentaires avec fossiles brisés et/ou remaniés et des réductions d'épaisseur. Plus à l'Est, le Toarcien est très réduit et (tectoniquement?) en contact avec le Dogger. Au Sud-Ouest en revanche, prés de Bolhos, la série toarcienne est plus complète et couronnée par l'Aalénien inférieur, mais tronquée par un contact oblique N-S, repris par la tectonique récente. Sur ce flanc, le Bajocien inférieur est représenté mais peu épais; il est suivi par le Bajocien supérieur, le Bathonien et le Callovien très développés qui sont recouverts par un "Lusitanien" épais, très différent de celui du flanc nord. Cette série du Jurassique moyen et supérieur a été décrite dans la thèse de Christiane Ruget (1963). La structure de Serra de EI-Rei constitue une sorte de raccord E-W entre les importantes structures (diapiriques ?) méridiennes de Caldas da Rainha au NE et de Bolhos au SW. II s'agit d'une structure de tectonique distensive, en demi-graben, d'âge jurassique, qui est responsable de la dissymétrie des séries lithostratigraphiques sur ses deux flancs; au Miocène, pendant la compression bétique, cette structure a subi une inversion en constriction. Un modèle de l'évolution sédimentaire du secteur est présenté.

Mots(dits) écrits:formes et valeurs de la diffusion des idées au 18ème siècle, au Portugal

Les rapports complexes entre les différentes façons de faire circuler les idées et les informations ne datent pas de nos jours. A toutes les époques, les messages qui circulent emploient toutes sortes de véhicules et de langages, très souvent complémentaires. Ces véhicules et ces langages n'ont peut-être rien d'extraordinaire. Ils appartiennent au monde des gestes de tous les jours, des gestes qui se répètent et dont la répétition est elle-même importante pour la construction du sens de chaque message. Ces gestes qui sont répétés, qui sont attendus et qui sont reconnus incluent des sons, des images, des comportements, des mots, ou des citations. Il y a donc un rapport qui s'y établit entre répétition et nouveauté, rapport dans lequel la répétition fournit chaque fois une nouvelle information, même si elle est déjà attendue, tandis que leur absence peut représenter l'anxiété, ou même le scandale.

«Oír o galo cantar dúas veces» - Identificacións locais, culturas das marxes e construción de nacións na fronteira entre Portugal e Galicia

Uma obra sobre a cultura de fronteira, num tempo longo (1800-2008). Na primeira parte, abordam-se aspetos da cultura de orla, associados à relação entre a little community e a comunidade imaginada, conferindo centralidade ao fenómeno do contrabando e às mais recentes estratégias patrimonializantes. Na segunda parte, trata-se em profundidade o tratado de limites entre Portugal e Espanha, de 1864, inserindo-o num tempo de demarcação das nações, e interrogando os antecedentes, os participantes, as questões tratadas e os formatos de resistência à sua concretização. Na terceira parte, interroga-se a noção de “acontecimento”, sub-tratada na antropologia, através de dois estudos de caso, trágicos e marcantes, que ocorreram na fronteira.

Princípios orientadores da formação, ao nível do 1º ciclo: a cooperação Portugal/P.A.L.O.P.'s

Os Países Africanos de Língua Oficial Portuguesa (P.A.L.O.P.'s), tal como a grande maioria de todo o continente africano, apresentam graves deficiências quanto a alfabetização das suas populações, tomando-se, assim, o ensino primário uma prioridade absoluta. De entre todas as limitações que existem ao nível dos respectivos sistemas educativos, talvez, a mais grave seja a fraca preparação científica e pedagógica que a maioria dos professores apresenta, para além, evidentemente, do seu reduzido número. Assim, a formação de professores tornou-se numa das apostas mais fortes dos P.A.L.O.P.'s, no campo da educação. Portugal, na área da cooperação com estes países, participa num Projecto de Consolidação dos Sistemas Educativos, no âmbito do qual desenvolve um programa de Acções de Formação de Formadores.

Pine processionary moth (Thaumetopoea pityocampa) and great tit (Parus major) in Portugal

In the present work, we studied a common outbreaking Lepidoptera species in Portuguese pine stands – Thaumetopoea pityocampa (Den. & Schiff.) - and one of its potential predators – Parus major (L.). The population dynamics of the immature stages of the Lepidoptera was studied in several types of Pinus pinaster (Aiton) plantations in three different areas: Setúbal Peninsula, Abrantes and National Pine Forest of Leiria. Location and plantation structure was the most important factors determining population density of T. pityocampa. Setubal and Abrantes was highly susceptible to attacks by the Lepidoptera, whereas Leiria had lower densities. Young and homogeneous pine stands was more susceptible to attacks than older and more heterogeneous pines stands. However, a desynchronized population of T. pityocampa, in which the larvae develops during summer instead of during winter, reached high densities also in Leiria. The impact of several mortality factors and climatic conditions on the immature stages of the insect (eggs and larvae), in normal and desynchronized populations are discussed, as well as possible evolutionary implications of the sudden appearance of the new version of T. pityocampa. The break of the pupa diapause and adult emergence times the annual life cycle of this insect. Adults from the desynchronized population emerged earlier than adults from the normal population, which in turn determined the change in the larvae development period. Different factors, potentially affecting the timing of adult emergence in both normal and abnormal populations are also discussed. To study P. Major, nest-boxes were placed in the areas of Setúbal and Leiria and they were monitored during three seasons. The nest-boxes increased the density of breeding and wintering birds in the studied pine plantations, indicating that a lack of natural holes are in fact a limiting factor for this populations. The earliest breeding start for this species was recorded in my study area, indicating that Portuguese coastal pines provide good breeding conditions earlier than in other areas of Europe and North Africa. This leads to an overlap between the end of the larvae stage of T. pityocampa and the beginning of the breeding season of P. major. Key-words: Thaumetopoea pityocampa, Parus major, Pinus pinaster, population dynamics, Portugal.

Les Hipparion du Portugal

This paper is concerned with Hipparion from Ribatejo, Portugal, and with the stratigraphy of the Neogene series of this region. The first two chapters are an introduction and an historical review. Paleontological study includes both a revision of the specimens accounted by ROMAN (1907) and the description of new material. Two forms were recognized, an early H. cf. primigenium, lower Vallesian in age, NM 9 mammal unit (from Archino, Vila Nova da Rainha, Aveiras de Cima), and a more advanced H. primigenium cf. melendezi. Upper Vallesian, NM 10 (possibly lowermost Turolian, NM 11) (at Azambujeira and Marmeleira). A synthesis of Middle and Upper Miocene from Ribatejo is also presented. Levels with H. p. cf. melendezi are somewhat older than «Upper Pontian», as it was previously acknowledged, they attain at the best the lowermost Turolian (approximately corresponding to «Upper Pontian»). Even higher levels may be Turolian in age, though they are not yet accurately dated. Almost all the localities are shown (tableau 11) according to its stratigraphical position; age, correspondance to mammal units from NM 5 to NM 10 (and may be also from NM 11 to NM 12), and correlation with marine formations near Lisbon are also taken in account. The stratigraphical position of localities such as Póvoa de Santarém, Quinta do Marmelal, Pero Filho, Azambujeira (lower levels), and Fonte do Pinheiro was revised; the stratigraphical position of Marmeleira was ascertained. The localities so far known correspond to NM 5 (?), NM 6, NM 8, NM 9, NM 10 and possibly to NM II and NM 12. A new interpretation (M. T. ANTUNES) of localities with oysters from Ribatejo allows a better correlation with vertebrate localities. Relationships with Serravallian transgression seem well established. Only two localities, Vila Nova da Rainha and Foz do Alviela, may possibly be correlated to V-b division of Lisbon (Langhian) with «Hispanotherium fauna». All the other localities are younger than Serravallian oyster beds. Undirect correlation shows that NM 6 localities are somewhat younger than the apogee ef Serravallian transgression (corresponding approximately to Blow's N 11 to N 13 zones based on planctonic foraminifera).

Premiers resultants d’une prospection paléontologique dans le Trias de l’Algarve (Portugal)

A three-week paleontological prospection in Triassic beds of the Algarve (southern province of Portugal) has revealed the presence of fossil vertebrates (stegocephalians for the most part, but also fishes and reptiles) in several localities and in at least 5 stratigraphical levels.

Ensaio de síntese crítica acerca do Cretácico terminal e do Paleogénico de Portugal

A synthetic essay about portuguese Late Cretaceous (Upper Campanian-Maastrichtian) and Paleogene is presented. This does include most of the so far known data, a critical approach to the problems of such formations, and to previous works on them. Our viewpoints (party original) are exposed in a shorter text in French where most of the discussion was suppressed (see reference in Resumo).
