Sedimentología y caracterización paleoambiental de la serie cretácica inferior de Antromero-Luanco (Asturias)

Abstract

A paleoenvironmental study for a Lower Cretaceuos (Late Barremian-Aptian) succession (Antromero-Luanco section, Asturian coast) is showed in this work based on stratigraphic, sedimentological and paleontological data. The lower part of the succession shows terrigenous deposits (the Peñaferruz Fm) recording fluvial and fan-deltaic sedimentation, while the upper part is characterized by shallow-water carbonates (the Antromero Fm) covering a broad carbonate platform environments from restricted to open marine zones. Fossil associations had been very helpful in order to interpret the main environmental features
