Late Quaternary tectono-sedimentary processes on an isolated offshore high marg...
López-Pérez, A.E.; Rubio, B.; Rey, D.; Plaza-Morlote, M.; Pinheiro, L.M.Studies of the most surficial sedimentary record from passive continental margins provide crucial knowledge about sedimentary dynamics and its changes through recent geological times. These studies allow understanding in detail the influence of both tectonic activity and long-term bottom-current circulation over the Late Quaternary sedimentary dynamics. Using a large dataset of multibeam bathymetry, chirp and m...
Seismic characterization of fluid migration and Pockmarks formation in the Estr...
Duarte, D.; Magalhães, V.H.; Terrinha, P.; Ribeiro, C.; Pinheiro, L.M.; Benazzouz, O.; Jung-Hyun, K.: A field with more than 30 pockmarks was recently discovered in the Estremadura Spur outer shelf (Lourinhã Monocline). The processing of high-resolution seismic lines permitted the characterization of this pockmark field and of the seismic sequence of the Plio-Quaternary basin where they occur. Results show that this region has been affected by several episodes of fluid migration and fluid escape during the Pl...
