Abstract[ES] El estudio de perfiles sismicos de alta y media resolución permite diferenciar varios sistemas deltaicos holocenos situados en la plataforma continental catalana y edificados por los rios Llobregat, Besós y Foix. El sistema deltaico actual esta representado por facies prodeltaicas, estando solapadas las de los rios Llobregat y Besós. Su principal caracteristica es la de presentar en el prodelta proximal facies sismicas opacas, con apantallamientos acústicos debidos a la presencia de gas y materia orgánica en el sedimento. El prodelta del Rio Foix está separado de los dos anteriores y no presenta facies sismicas opacas
[EN] Two different deltaic iblocene systems have been identified in the Catalan Continental Shelf (Northwestem Mediterranean Sea), by high and medium resolution seismic rof files. These systems are built by Llobregat, Besos and Foix rivers. Recent deltaic system is represented by overlapping prodeltaic facies from the Llobregat and Besos rivers. Proximal prodelta is characterized by opaque seismic facies with acoustic maskings due to the presence of gas and organic matter within the sediment. Foix prodelta is isolated and does not show opaque seismic facies
