Segundo M. Varela Gomes, responsável pela escavação, em Março de 2000, de um dos dois silos postos a descoberto por trabalhos de construção civil, o enchimento inclui materiais arqueológicos - cerâmicas, moedas e outros artefactos metálicos - e restos de fauna. Indicam tratar-se de lixo, deitado para o silo depois de desactivado; datando dos primeiros tempos da ocupação cristã (segunda metade do séc. XIII), a j...
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...
Correlation between facies associations (marine, estuarine and distal fluviatile environments) and disconformities, observed between Foz da Fonte (SW of Setúbal Peninsula) and Santa Iria da Azóia (NE of Lisbon) are presented. The precise definition of the marine-continental facies relationships improved very much the chronology of the depositional sequence boundaries. Tectonic and eustatic controls are discusse...
Eight depositional sequences (DS) delimited by regional disconformities had been recognized in the Miocene of Lisbon and Setúbal Peninsula areas. In the case of the western coast of the Setúbal Peninsula, outcrops consisting of Lower Burdigalian to Lower Tortonian sediments were studied. The stratigraphic zonography and the environmental considerations are mainly supported on data concerning to foraminifera, os...
A synthesis about the Neogene and Quaternary of Algarve (Southern Portugal) is presented. New isotopic 87Sr/86Sr ages as well as biostratigraphic data about the Miocene deposits allow to present a new stratigraphic frame for the previously characterized units. The Lagos-Portimão Formation corresponds to deposits of temperate carbonate platform sedimentological type, developed during a long time span (Lower Burd...
The "Ostracoda: database for the Neogene of Portugal", prepared under the Project "POCTl/36531/PAL/2000 - Studies on Portuguese Palaeontology / Post-Paleozoic", is presented. It provides information about 158 especies that have been recognized in sections and boreholes concerning Neogene units in Portugal.
O achado de um dente de mastodonte, cf. Tetralophodon longirostris, em depósitos marinhos expostos na praia de Penedo Norte, na Península de Setúbal, permitiu datação rigorosa. Provém da camada 8 do corte, parte basal da sequência deposicional T1; data do início do Tortoniano, ca. de 11.6 Ma, com base em foraminíferos planctónicos (zona N14) e em 87Sr/86Sr e K/Ar. O dente de mastodonte parece pertencer a Tetra...
6º Simposio sobre el Margen Ibérico Atlántico MIA09 ; In Portugal mainland Cenozoic sedimentation occurred largely but allocated to several basins. Even in the same basin, the sedimentary record shows significant lateral changes in facies and thickness. However, the main sedimentary ruptures and overall lithologic characteristics of the infilling stages are quite similar in the several basins, reflecting the g...
Revista electrónica de Ciências da Terra,http://e-terra.geopor.pt,Geociences on-line journal, Vol. 6, nº1 ; In the Lower Tagus Basin (Setúbal Peninsula, Portugal), biostratigraphic data as well as isotopic dating allowed an age of 11.6 Ma to be ascribed to the lower boundary of the local depositional sequence T1 (Antunes et al., 2000; Legoinha, 2001). Hilgen et al. (2005) announced the new GSSP of the Tortonia...
Pela sua grande riqueza paleontológica, sobretudo no que diz respeito a fósseis miocénicos,as arribas litorais e ribeirinhas do Concelho de Almada merecem ser incluídas no Património Paleontológico Português, de acordo com critérios científicos, pedagógicos e culturais, entre outros. Enumeram-se razões justificativas dessa inclusão, para algumas jazidas seleccionadas, consideradas mais representativas da totali...
