Age of evaporite flow or deformation (when deformed)
Other comments Stratigraphic successions of Early Miocene age (Tórtola, Villalba de la Sierra and Valdeganga depositional systems) include interbedded deposits of playa-lake and meandering river environments. Middle-Late Miocene evaporites originated in the late functional stage of the Villalba de la Sierra fluvial fan.
