摘要: Abstract 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 coincidence between ravinement surface maximum flooding surface. During stage, shoreface erosion prevailed over sedimentation, leading to development palimpsest relict facies. accumulation occurred only in areas with a steady supply sediment, favouring depositional mound Fluvia-Muga Ter prodeltas. Their distribution resulted from southward geostrophic current flow physiographic configuration area.
