AB The Puebla de Guzmán and Valverde del Camino Anticlines consist of fault-propagation folds linked to afrontal thrust system striking N110ºE. In the Puebla de Guzmán Anticline, the thrust system has a fan imbricatedgeometry and represents a ~40 km-long and 4-5 km-wide frontal ramp; its internal structure results fromthe tectonic stacking of thrust sheets with normal stratigraphic polarities. Some thrusts show relay geometries,as for example the Valdecascajos and the Sierra de la Estrella Thrusts. An antiform-sinform system is developedin the intervening thrust sheet. Fault-propagation folds are very conspicuous in the hanging wall of mostinternal thrusts, where a rather continuous reverse limb is present. Both thrust system and fault-propagationfolds, as well as a locally developed crenulation cleavage, were generated in a second tectonic phase
