Estratigrafía secuencial de sistemas deltaicos en cuencas de antepaís: ejemplos de Montserrat, Sant Llorenç del Munt, Montserrat y Roda (Paleogeno, cuenca de Antepaís surpirenaica).

After the sedimentological study of the Sant Llorenc del Munt, Montserrat and Roda deltaic systems, a stratigraphic subdivision based on three different scale transgressiveregressive sequences has been developed. This subdivision has been established on the coastal facies belts from the deduced shoreline (and associated facies belts) migration. These transgressive-regressive sequences are formed by a lower transgressive part with a deepening-upwards trend and a retrogradational staclung pattern and an upper regressive part, with shallowing-upwards trend and a progradational stacking pattern. The lowest scale sequences (metrical) have been named 'fundamental sequences'. A series of 'composite sequences', intermediate scale (decametric to hectometric), have been defined afier the study of the staclung pattem of the fundamental sequences. After the study of the stacking pattem of composite sequences there have been defined a series of large-scale (decametric to kilometric) 'composite megasequences'.
