Carbonate platform margin facies evolution: the Aptian of Mundaka (Bizkaia, Northern Spain)

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 carbona...

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
