Classif. (Jackson and Talbot, 1986)
Age of evaporite flow or deformation (when deformed)
Other comments Structural and stratigraphic origin related to the Guarga thrust. Central External Sierras show a set of N-S to NW-SE anticlines, perpendicular to the structural trend of the Pyrenees, that become younger and smaller westwards (Pico del Águila, Bentué de Rasal, Gabardiella, Rasal; see Vidal-Royo, et al., 2013). Interpreted to have formed on oblique ramps of south-verging thrusts (e.g., Pueyo et al., 2002), or as a result of westward propagation of deformation during early Bartonian to Priabonian times (Labaume et al., 2016).
