Xauen seamounts, which are three aligned antiforms (Bourgois et al. 1992; Martínez-García et al. 2011, 2013; Estrada et al. 2018), and the Campo de Dalias folds
(Pedrera et al. 2015) (Figs. 6.7 and 6.8a, b). These last folds form three smooth,
elongate elevations (N50-60), located to the W of Chella Bank, which are 15–20 km
long and 30–80 m high (Vázquez et al. 2016). They are interpreted as anticlines
associated with blind thrusts affecting the recent sediments.
Faults are grouped into two main sets of N25
E sinistral and N130
E dextral
