The sedimentological and stratigraphic study of the section, composed of up to 160 m of terrigenous, mixed (marls), coal and carbonate deposits, allowed characterizing three depositional environments: distal alluvial, lacustrine and palustrine. The stratigraphic arrangement of different facies reflects five 28-43 m thick sequences which are related to progradation and retrogradation of alluvial systems and consequent retraction and expansion of the lacustrine and palustrine wetlands. The alluvial deposits have been associated with the alluvial fans of the northern basin margin, which was activated by the compressive tectonics prevailing during the time of deposition. info:eu-repo/semantics/openAccess by-nc-sa https://creativecommons.org/licenses/by-nc-sa/4.0/deed.es 0.2 2024 0.168 2024 Geology 2024 Q4 0.4 2024 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Arenas, Concha Universidad de Zaragoza (orcid)0000-0002-4212-0524 Baceta, Juan Ignacio Murelaga, Xabier 2000 280 Universidad de Zaragoza Dpto.
