Two fining-upward successions have been identitied in the unit by studies of vertical changes of lithofacies associations in tbe northern part of the basin. The Iower fining-upward succession corresponds to deposits of coalescent wet alluvial fans, changing to a braidplain witli local sinuosity. The upper succcssion records the transition from high slope braidplains with increasing sinuosity to fluvial-dominated deltaic deposits. Considering the available biostratigraphic data, the allocyclic controls on vertical changes of lithofacies assoeiations is discussed. It was inferred that the climate or a basin margin uplift were not the main control on system charaeter clianges. Furthermore, evidence in the offshore suggests that sea-level changes probably had a major influence. We believe that the onset of seafloor spreading in the Galician western margin and Bay of Biscay during upper Aptian to middle Albian have caused sea-level variations in the Lusitanian Basin, related to the thermal and isostatic adjustments. A relationship was admitted between the custatie curves of Haq et aL (1988) and the North Atiantie (Iberia included) geodynamic evolution. In the unit studied, the lower fining-upward succession probably corresponds to the supercycle LZB-4 and the upper tining-upward succession to UZA-i and part of the UZA-2 of Haq etal. (1988).
