Rifting of the Southwest and West Iberia Continental Margins

Identification and characterization of geological formations with CO 2 storage potential in Portugal

“…During the Late Cretaceous-Late Miocene, important changes associated with the collision of the Iberia microplate with Eurasia or Africa led to the reactivation of extensional faults developed during the rifting stages (Fig. 4) (Terrinha et al 2019a).…”

Age of the basement beneath the Mesozoic Lusitanian Basin revealed by granitic xenoliths from the Papôa volcanic breccia (West Iberia)

“…The discussion on the nature of the Paleozoic tectonic unit that constitutes the pre-Mesozoic basement of the Lusitanian Basin is still ongoing, with a number of authors pointing to a range of possibilities: i) the CIZ (Terrinha et al, 2019); ii) the OMZ and CIZ (Oliveira et al, 1992;Pereira et al, 2016); iii) the OMZ and SPZ (Alves, 2011;Capdevila and Mougenot, 1988;Kullberg et al, 2013); iv) the SPZ (Ribeiro et al, 2007); and v) the CIZ, OMZ and SPZ (Pimentel and Pena dos Reis, 2016). However, there is a clue that may help to solve the puzzle.…”

The Late Pleistocene-Holocene sedimentary evolution of the Sines Contourite Drift (SW Portuguese Margin): A multiproxy approach

“…The Alentejo Margin is located in the West Iberian Margin, which was formed as a consequence of the breaking up of Pangaea during Triassic (Terrinha et al, 2019a) and subsequent Mesozoic rifting (Boillot et al, 1989;Pinheiro et al, 1996) that led to break-up during the Early Cretaceous (e.g., Terrinha et al, 2003). During Pliocene-Quaternary times, the SW Iberian Margin was subject to WNW-ESE oriented horizontal compression that favoured fault reactivation as evinced by offshore extensive seismicity (Terrinha et al, 2019b).…”
