Biostratigraphie et paléoécologie des peuplements d'ostracodes dans le Domérien...
N'Zaba-Makaya, O.; Andreu, B.; Brunel, F.; Mouterde, R.; Rey, J.; Rocha, R. B.The Domerian sections from the Lusitanian Basin of São Pedro de Muel, Rabaçal and Tomar have provided us with more than 1100 Ostracods belonging from 18 genus and about 48 species. The faunal diversity and density of the associations decrease in space (from Tomar to Rabaçal and São Pedro de Muel) and time, with favourable environments for the proliferation of Ostracods at the lower part of the sections (Stokesi...
Stratigraphie du Dogger et crise lusitanienne dans la Serra de Candeeiros
Ruget, Ch.; Thierry, J.; Rocha, R. B.; Delance, J. H.; Laurin, B.; Mouterde, R.; Tintant, H.New elements about the stratigraphy of the Serra de Candeeiros Dogger and Lower «Lusitanian» are presented. The Lower Aalenian was recognized for the first time. Bathonian (more than 50 metres thick) is dated on brachiopods and foraminifera. It corresponds to a series of massive micritic, biodetritical, coral-reef, chaetetid, bryozoa and oolitic-limestones. Callovian (120 m) begins by whitish or yellowish limes...
Essai de biozonation du Domérien portugais
Mouterde, R.; Rocha, R. B.The biozonation of the portuguese Domerian is presented. This biozonation is based essentially on fauna from the following sections: S. Pedro de Muel, Peniche (Stokesi zone and lower part of the Margaritatus zone) and Brenha (Margaritatus and Spinatum zones). The distribution of the main fossil groups enabled an accurate division of the Stokesi zone into three horizons: Occidentale, Monestieri-Nitescens and Lus...
Sedimentation pelagique et encroûtements cryptalgaires: les calcaires gremeleux...
Elmi, S.; Rocha, R. B.; Mouterde, R.In Portugal, Carixian is generally represented by alternative layers of marly limestones characterized by nodule and lumpy levels. These layers are particularly developped [show preferential development] on passage areas to a sedimentary basin, particularly along the slope of tilted blocks between the Meseta and Berlenga's horst. This facies is included in the range of the «nodular limestone» and of the «ammoni...
Faciès, biostratigraphie et paléogéographie du Jurassique portugais
Mouterde, R.; Rocha, R. B.; Ruget, Ch.; Tintant, H.The facies distribution along the Jurassic stages in an already well established stratigraphic frame is defined for the three portuguese basins: North of Tagus, Santiago de Cacém and Algarve. The deposits are organized in two sedimentary cycles. The first one from the Liassic to Calovian shows, in the Tagus Basin, a transgression from NW which did not surpass the Meseta present limits. The iniatilly brackish de...
Les acanthopleurocératinés portugais et leurs relations avec les formes subboré...
Dommergues, J.-L.; Mouterde, R.The evolution of the Portuguese Acanthopleuroceratinae is similar to the celto-souabe succession such as it was described in the collects of the Cottards (Cher, France). A subspecies of one of the oldest Acanthopleuroceras (A. carinatum atlanticum) is abundant in the lower part of the Portuguese Ibex zone; this form is described here. The species is recognized in France by several nuclei associated with A. arie...
Toarcian GSSP candidate: the Peniche section at Ponta do Trovão
Elmi, S.; Mouterde, R.; Rocha, R. B.; Ruget, Ch.The Peniche section (Ponta do Trovão) in Portugal is presented as potential stratotype (GSSP) for the Pliensbachian/Toarcian boundary. The lithostratigraphic succession is described and the chronostratigraphy, based on ammonite assemblages, is presented; the change in foraminifera assemblages occurs later, only at the base of beds 16 (base of Semicelatum Subzone, Crosbeyi ? Horizon). An extensive bibliographica...
Atlas des fossiles caractéristiques du Lias portugais* III a) Domérien (Ammonites)
Mouterde, R.; Dommergues, J.-L.; Meister, C.; Rocha, R. B.This fascicle, dedicated to the Domerian (Late Pliensbachian) ammonites faunas, is the third part of the “Atlas des fossiles caractéristiques du Lias portugais“. It follows two previous publications about the Hettangian-Sinemurian and the Carixian (Lower fifty species are concisely described and illustrated. The other groups (nautilids, belemnites, brachiopods, bivalvia...) will be published afterwards. The pri...
Une succession de référence pour le Toarcien Moyen et Supérieur: les "Margas ca...
Elmi, S.; Mouterde, R.; Rocha, R. B.; Rulleau, L.The geological sections studied at the São Gião sector (Cantanhede region) have allowed the establishment of a clear succession of ammonite associations during the Middle and Upper Toarcian (“Margas calcárias de São Gião” and “Calcários margosos de Póvoa da Lomba” Formations). The fossil collections were gathered over the last 40 years and, in spite of the apparent facies monotony, come from a thick and fossili...
Henri Tintant face au problème "Science et Foi"
Ruget, C.; Mouterde, R.From an early age Henri Tintant was conforted with the problematic relationships between Science and Faith. After a traditional religious education, he took responsabilities within groups of teenagers and adults through scouting and the J. E. C. (an organisation of catholic students). In 1940 he was at Montpellier distributing unauthorised leaflets defending religious faith. But more significant is his intellec...
