Marine terrace staircases of western Iberia: Uplift rate patterns from rocky li...

The Western Iberian Peninsula is undergoing compressive tectonic reactivation, resulting in spatial and temporal variations of surface uplift. Uplift quantification can be undertaken in coastal settings using staircases of shore platforms developed onto rocky headlands. This study analyses two marine terrace staircases in central Portugal: Cape Raso - Abano beach and Cape Espichel. Geomorphic and stratigraphic ...

Pegadas de terópodes da Formação de Papo Seco (Barremiano inferior, Cabo Espich...

RESUMO: Descrevem-se novas pegadas de terópodes encontradas na Boca do Chapim, a norte do Cabo Espichel (Formação de Papo Seco, Barremiano inferior). Quatorze pegadas de terópodes foram identificadas na primeira camada desta formação. Foram identificados dois tipos diferentes de pegadas de terópodes, que ocorrem em diferentes áreas e níveis desta camada. O primeiro tipo, constituído por pegadas mais pequenas e ...

Caracterização de pegadas de terópodes no Oxfordiano superior do Cabo Mondego, ...

RESUMO: São analisadas dez pegadas de dinossauros, ocorrendo em dois estratos do topo das “Camadas com Pholadomya protei” (Oxfordiano superior) do Cabo Mondego (Figueira da Foz), sector norte da Bacia Lusitânica. Trata-se de pegadas que podem ser observadas na superfície das camadas ou em seção transversal, por vezes representando estruturas que deformam muito o substrato. O material icnológico encontra-se dist...

Marine terrace staircases of western Iberia: uplift rate patterns from rocky li...

The Western Iberian passive margin is under compressive tectonic reactivation resulting in spatial and temporal variations in surface uplift. This uplift can be quantified in coastal settings using staircases of wave-cut platforms developed onto rocky headlands. This study focuses on two marine terrace staircases of central Portugal: Cape Raso (west of Lisbon) and Cape Espichel (western Arrábida mountain chain)...

Plio-Quaternary coastal uplift along the western Iberian margin: insights from ...

This study provides a detailed geomorphological study of the Peniche Peninsula, located in westernmost Iberia, a resistant rocky limestone headland subjected to high energy Atlantic Ocean coastal processes. We have used field mapping, surveying, sedimentary facies analysis, geochronology (electron spin resonance [ESR]; U-Series), but also identification of fossils and lithic artefacts, in order to: 1) reconstru...

Quaternary Earth-science and Palaeolithic conservation initiatives in the Tejo ...

Geoconservation measures in the River Tejo, the Portuguese reach of the Tagus, are compared with those in the Thames downstream of London (UK). Both are fluvio-estuarine reaches with staircases of Pleistocene depositional terraces, each with important sedimentary, palaeontological and archaeological records. In both rivers, conservation measures are in place that aim to protect these records, promote research a...

Aurochs roamed along the coast of SW Spain (Iberia) during Late Pleistocene

In the Iberian Peninsula the fossil record of artiodactyls spans over 53 million years. During the Pleistocene, wild cattle species such as Bison and especially Bos became common. In Late Pleistocene, the aurochs (Bos primigenius) was widespread and the only bovine living along the large river valleys of southern Iberia. Although commonly found in fossil sites and especially in cave bone assemblages, the trace ...
