Zusammenfassung
The siliciclastic and carbonate deposits of the upper Albian to lower Cenomanian Oiartzun Formation, which crop out to the southeast of Donostia-San Sebastián (NE margin of the Basque-Cantabrian Basin), record the evolution of the coeval growth of salt-influenced forced-folds (anticlines), in an extensional rifting context. Facies analysis indicates the distinct spatial distribution of sedimentary environments in a braidplain delta depositional system over a relatively reduced area, due to the synsedimentary growth of the Txoritokieta and Oiartzun forcedfolds. The growth of these folds conditions the depositional relief and impact not only in the facies distribution but also in stratigraphic thicknesses in the fold limbs.
