Secuencias deposicionales de tercer orden en el Eoceno de la Cuenca de antepaís surpirenaica oriental

A basin analysis of the Eocene South-Eastern Pyrenean Foreland Basin shows a backstepped geometry of the basinfill made up of four main basin steps, each one infilled by a sedimentary sequence recognized as a third-order Depositional Sequence. This basin architectural stacking is due to a stepped ev...
