In the middle and upper Eocene strata of the South Pyrenean foreland basin, three sedimentary cicles have been distinguished. These cycles are bounded by angular uncorfirmities, each cycle being related to the development of a particular thrust system. The stiking of the thrust systems is recorded by rhe angular uncorformities that bound the cycles
Se han distinguido tres ciclos sedimentarios en los estratos del Eoceno medio y superior de la cuenca del cabo sur de los Pirineos. Los ciclos están unidos por discordancias angulares, estando cada ciclo relacionado con el desarrollo de un sistema particular de cabalgamiento.
