| Sumario: | Platform margin as well as foreslope settings are heterogeneous and constitute key elements to understand carbonate platform system dynamics. Aptian outcrop exposures along the Mundaka cliffs in the Basque-Cantabrian basin were investigated to assess the development of a variety of facies in carbonate margin and foreslope settings. The measured Santa Catalina section displays a series of rudist-coral bioherms revealing changes in water depth together with significant variations in turbidity. Relative sea-level trends were inferred from facies associations, which helped indentify three transgressive-regressive cycles. This depositional record provides baseline data to predict margin and foreslope evolution, geometry and heterogeneity in sedimentary basins with prospective hydrocarbon targets |
