Historical building dating: A multidisciplinary study of the Convento de São Fr...

Cross-dating of bricks and mortars from historical building, through thermal (TL) and optically stimulated (OSL) luminescence have achieved good accuracy and precision. However this approach is, in many cases, not exhaustive especially for buildings with different construction phases closely temporally spaced to each other. The uncertainties of experimental data added to the reuse of old bricks and/or the prese...

Characterization of the sedimentary record of the AD1755 tsunami in the Martinh...

This study addresses the Holocene sedimentary succession at Martinhal coastal lowland (Algarve), a site recording the AD1755 Lisbon tsunami. Data on twenty-four short cores and sixteen trenches, retrieved from both the literature and new field work were combined to improve the stratigraphic resolution and lateral correlation of sedimentary units accumulated in this lowland. Four fining-upward depositional seque...

Geomorphological constraining of tsunami (?) run-up in the Alcantarilha coastal...

The Alcantarilha lowland, partly barred by a well developed barrier, including foredunes covering Pleistocene-Holocene beachrock and aeolianite, develops across the Alcantarilha infilled estuary, the beach-dune extending further SE until the Salgados lagoon. A topographic and coring survey revealed a peculiar feature at the leeward toe of the dune ridge close to the inlet area: a sandy fan with location, shape ...

Detrital zircon geochronology of the Cretaceous succession from the Iberian Atl...

Vegetational composition of the Early Cretaceous Chicalhão flora (Lusitanian Ba...

A new Early Cretaceous flora is described from the Lusitanian Basin in the Estremadura region (western Portugal) based on a combined study of mesofossils and palynomorphs. The fossil specimens were extracted from samples collected in the Chicalhão clay pit complex, near the village of Juncal from sediments belonging to the Figueira da Foz Formation. The plant bearing sequence is considered to be of Late Aptian–...

Paleogeographic evolution of the Nazaré-Salgado coastal zone (Portugal) during ...

The Nazaré-Salgado coast develops NE-SW along 7km, some 100km north of Lisbon. About 5ka years ago, the Nazaré-Salgado coast formed the coastline of the Pederneira lagoon, with a rocky inlet connecting the sea and an inner basin that silted up in the late 17th century AD. Two cores were taken from the plains and four trenches dug in the southern dune ridges to validate GPR data; morphological changes since 1957...
