11 pages, 8 figures The Valencia Fan developed in the Valencia Trough at the lower end of the Valencia Valley and the Blanes Canyon. The morpho-sedimentary features of the upper, middle and lower fan, studied from high-resolution sparker reflection profiles, indicate cyclic updip-downdip migrations of fan depocenters during the Plio-Pleistocene. These migrations were caused by changes of sediment input related to the Plio-Pleistocene climatic-eustatic sea-level variations. During periods of sea-level lowering, the system migrated downbasin and developed extensively on the deeper sectors of the Valencia Trough. During periods of sea-level rise, the fan sedimentation migrated updip, abandoning the deeper areas of the basin. The Valencia Fan is not affected by significant lateral migration because it developed in a basin constricted between two land masses. As a consequence, longitudinal progradation and retreat of fan deposition produced a vertical stacking of fanlobes displaced alternatively updip and downdip. These growth patterns reveal some differences with respect to classical deep-sea fans. © 1994
