El surco sedimentario de Elkuden (Albiense superior-Cenomaniense inferior, Navarra)

Abstract

7he Elkuden sedimentary succession comprises mainly silty and marly facies with scarce intercalated calcarenitic gullies and breccias. Integrated fades and biostratigraphic analyses provide the basis for sedimentary environment reconstructions during the late Albian-early Cenomanian. A small sedimentary trough (4x1 km.) neighbouring a carbonate platform was formed by synsedimentary activity of the strike-slip Bilbao fault
