Hinge movements influencing deposition during the Upper Devonian in the Esla area of the Cantabrian Mountains, Spain

Abstract

In the Upper Devonian succession the presence of allochthonous lithological elements and replaced fossils, a regular vertical alternation of layers of coral rubble and biostromes, and abundant indications of erosion and subareal exposure can be explained by application of a regional epeirogenetic model. Epeirogenetic movements governed sedimentation and led to a regressive and a transgressive depositional phase. The Portilla Limestone Formation and the Nocedo Formation have been mainly deposited during the regressive phase; the deposits of the Ermita Formation reflect the transgressive phase.
