- Calibração biostratigráfica das unidades sísmicas da Bacia offshore do Algarve: contribuição do core SWIM04-39Publication . Roque, Ana Cristina; Terrinha, Pedro; Cachão, Mário; Ferreira, J.; Legoinha, Paulo Alexandre; Zitellini, NevioEfectuou-se a calibração estratigráfica das unidades sísmicas mais recentes identificadas na Bacia offshore do Algarve recorrendo à análise biostratigráfica (Nanofósseis calcários e Foraminíferos) do core de pistão SWIM04-39. Obteve-se uma idade de cerca de 4.0 Ma (Pliocénico Inferior, Zancliano) para as associações fitoplanctónica e faunística presente nas amostras do referido core. Estes dados permitiram datar o início da intensa subsidência sofrida por esta Bacia como sendo Pliocénico Inferior.

- Morphostructure of the S. Vicente Canyon, Marquês de Pombal Fault and Pereira de Sousa Fault (SW Iberia margin)Publication . Cunha, D.; Roque, Ana Cristina; Silva, F.; Silva, E. A.; Lourenço, Nuno; Abreu, M. Pinto deThe S. Vicent Canyon (SVC), Marquês de Pombal Fault (MPF) and Pereira de Sousa Fault (PSF) are located along the SW Iberian margin. The SVC appears to be controlled by the S. Vicent Fault (SVF), a steep NE-SW striking fault that outcrops along the southeast flank of the canyon. To better understand the SVC, MPF and PSF structures and the Meso-Cenozoic morphostructural evolution of this sector it is important to identify the main tectonic phases from the Mesozoic up to Plio-Quaternary. To attain this objective, the main regional structures were mapped using 2D seismic lines and multibeam swath bathymetry data, allowing the mapping of the northern prolongation of PSF and the identification of faults that do not reach the sea floor.
