Late Pleistocene-Holocene sedimentary evolution of the northern Catalonia continental shelf (northwestern Mediterranean Sea)

The late Pleistocene-Holocene sedimentary evolution of the northern Catalonia continental shelf is interpreted as transgressive and highstand systems tracts, separated by an unconformity that seismically represents the coincidence between the ravinement surface and maximum flooding surface. During the transgressive stage, the shoreface erosion prevailed over sedimentation, leading to the development of palimpsest and relict facies. During the highstand stage, accumulation occurred only in areas with a steady supply of sediment, favouring the development of a depositional mound and the Fluviá-Muga and Ter prodeltas. Their distribution resulted from southward geostrophic current flow and the physiographic configuration of the area.
