Influence of Salt Diapirism on the Basin Architecture and Hydrocarbon Prospects of the Western Iberian Margin

Tectono‐sedimentary evolution of Jurassic–Cretaceous diapiric structures: Miravete anticline, Maestrat Basin, Spain

“…Recently, an increasing number of salt‐related structures were reinterpreted in the various Iberian fold and thrust belts as indicated by red circles in Figure 1 and discussed in Vergés et al (2019). These include the Basque‐Cantabrian Basin (1–4: Bodego & Agirrezabala, 2013; López‐Horgue et al, 2010; Poprawski et al, 2014; Poprawski, Basile, Jaillard, Gaudin, & Lopez, 2016; Quintà, Tavani, & Roca, 2012), the Pyrenees (5–9: Canérot, Hudec, & Rockenbauch, 2005; Jammes, Tiberi, & Manatschal, 2010; Lopez‐Mir, Anton Muñoz, & García Senz, 2014; McClay, Muñoz, & García‐Senz, 2004; Saura, Ardèvol i Oró, Teixell, & Vergés, 2016), the Iberian Range (10: Canérot, 1991), the Betics (11–16: Escosa, Roca, & Ferrer, 2018; Martínez del Olmo et al, 2015; Pedrera, Marín‐Lechado, Galindo‐Zaldívar, & García‐Lobón, 2014; Soto et al, 2017; Soto & Flinch, 2017), the Algarve Basin (17, 18: Ramos, Fernández, Terrinha, & Muñoz, 2016) and the Lusitanian basin (19, 20: Alves, Gawthorpe, Hunt, & Monteiro, 2003; Peno dos Reis, et al 2017).…”

The influence of halokinesis on prograding clinoforms: Insights from the Tiddlybanken Basin, Norwegian Barents Sea

“…However, its identification in salt‐related basins might be an issue since clinoforms could be eroded by post‐depositional diapir growth. Upper Jurassic deep‐water sediments deposited during a possible diapir‐induced force regression have been documented by Pena dos Reis, Pimentel, Fainstein, Reis, and Rasmussen (); Pimentel and Pena Dos Reis () in the Lusitanian Basin (Portugal), where outcrops show spectacular incised turbiditic channels occurring at one side of a large salt wall. Based on the forward models (Figures e, and d), diapir‐induced force regressions may be an important process of sediment delivery to the slope and basin floor in salt‐bearing basins.…”

Multi-layered salt-prone stratigraphy and its influence on rift-basin development; The Slyne and Erris basins, offshore NW Ireland

“…This leads to significant differences in the structural styles and evolution of salt-influenced basins relative to those unaffected by salt. Thick layers of salt have been encountered in several basins across the European Atlantic margin, including offshore Iberia (Alves et al, 2006;Pena dos Reis et al, 2017;Ramos et al, 2017;Zamora et al, 2017), offshore France (Chapman, 1989;Ferrer et al, 2012), on the United Kingdom Continental Shelf (UKCS) (Stewart et al, 1996;Jackson & Stewart, 2017) and offshore Norway (Jackson et al, 2019;Rojo et al, 2019). Salt is also present in basins on the conjugate margin of Atlantic Canada (Jansa et al, 1980;Deptuck & Kendell, 2017).…”
