Classif. (Jackson and Talbot, 1986)
Age of evaporite flow or deformation (when deformed)
Other comments Interpreted as an inverted diapiric structure thrusted towards the north during the Tertiary (see Camara, 2017). The evaporites of the Bilbao anticline core could be attributed to both the Upper Jurassic (Purbeck, see Abalos et al., 2008) and the Triassic age (Keuper, see Camara, 2017, 2020).
