Résumé
A new stratigraphic section of 235 metres is logged in the Robayera peninsula,where Early Aptian units are represented by shallow-marine facies. The sedimentary record was controlled by early tectonic activity. Four transgressive-regressive cycles have been recognized. The Late Bedoulian San Esteban carbonate platform was karstified, tilted and drowned at the top of the first cycle, and was subsequently overlain by three transgressiveregressive cycles of the Rodezas Formation. The Rodezas Fm stratigraphic type-section is described in Robayera including five units. The first three units wedge updip towards the synsedimentary Usgo N-S fault. The activity of this fault influenced the facies and sedimentary record of both Early Aptian Formations.
