Environmental changes and historical occupation at Oued Laksar (Ksar Seghir), Morocco
Laksar is a small river near the village of Ksar Seghir, located between Tangier and Ceuta (Morocco), strategic points to control the Strait of Gibraltar over centuries. The river outlets at the western part of a sandy beach that can block the fluvial discharge in years of low precipitation/river flow. The area is densely occupied since the 5th century BC, during the roman period and Early Middle Age in the archaeological site of Dhar d’Aseqfane,…
Elementos Arquitetónicos Do Teatro Romano De Lisboa / Olisipo
Analisa-se um conjunto de elementos arquitetónicos de época romana recolhidos nas intervenções arqueológicas realizadas no teatro romano. Estas peças destacam-se pelo facto de o material em que são elaboradas não ser o biocalcarenito de idade miocénica, empregue em todos os elementos decorativos e estruturais do teatro mas antes um litótipo distinto, pouco homogéneo e exótico, quer na cor quer na composição. A singularidade destes elementos arqui…
The role of climate, marine influence and sedimentation rates in late-Holocene estuarine evolution (SW Portugal)
Estuaries are sensitive to changes in global to regional sea level, to climate-driven variation in rainfall and to fluvial discharge. In this study, we use source and environmentally sensitive proxies together with radiocarbon dating to examine a 7-m-thick sedimentary record from the Sado estuary accumulated throughout the last 3.6 kyr. The lithofacies, geochemistry and diatom assemblages in the sediments accumulated between 3570 and 3240 cal. BP…
Single events and century-scale evolution of the northern margin of the Tagus River before the Boavista landfill
In this work we present preliminary results of the study of one sediment core (EDP1), collected near Cais do Sodré, Lisbon downtown, close to the present day Tagus riverfront. The results allowed differentiation of 4 major sediment units that present a signature of increasing anthropic influence over time. The lowermost unit (Unit 1) corresponds to a subtidal flat accreting in low energy and brackish conditions. This sedimentation pattern is inte…
O Pliocénico de Pombal (Bacia do Mondego, Portugal Oeste)
No presente trabalho são apresentados dados palinológicos inéditos da importante sequência do Pliocénico português em Pombal. Em paralelo, conjugando os dados dos vários proxies paleontológicos estudados nesta sequência, é feito o ponto da situação do conhecimento sobre nanofósseis calcários e associações de fósseis de moluscos, nomeadamente no que concerne ao seu significado biostratigráfico, paleoecológico e paleobiogeográfico. No tocante à Pal…
Lateglacial and Holocene environmental changes in Portuguese coastal lagoons 2
Benthic foraminiferal, ostracod, calcareous nannoplankton and diatom assemblages have been analysed from the 25.45 sedimentary succession of a borehole drilled in the Santo André lagoon (southwestern Portugal). The zones and subzones recognized according to their microfossil content have been used to define six palaeoenvironmental stages extending from the Lateglacial to the present. Stage A and the lower part of stage B (14.2 to 10.0 ka) represe…
