Other comments Upper part of the Beuda evaporites acted as a decollement during middle-late Eocene thrusting in the southern Pyrenees. Thick series of evaporitic rocks beneath the Ripoll Syncline (2000 m in the El Serrat-1 Well) interpreted as a stratigraphic unit passing laterally to turbidites (northwards) and shallow water carbonates (southwards), tectonically repeated into a duplex (see Carrillo, 2009).
