description [EN] The study of the Upper Jurassic-Lower Cretaceous deposits (Higueruelas, Villar del Arzobispo and Aldea de Cortés Formations) of the South Iberian Basin (NW Valencia, Spain) reveals new stratigraphic and sedimentological data, which have significant implications on the stratigraphic framework, depositional environments and age of these units. Moreover, these new data encourage revising the previously proposed stratigraphic correlations between the studied units and those deposited in adjacent areas of the Iberian Basin. The Higueruelas Fm was deposited in a mid-inner carbonate platform where oncolitic bars migrated by the action of storms and where oncoid production progressively decreased towards the uppermost part of the unit. The overlying Villar del Arzobispo Fm has been traditionally interpreted as an inner platform-lagoon evolving into a tidal-flat. Here it is interpreted as an inner-carbonate platform affected by storms, where oolitic shoals protected a lagoon, which had siliciclastic inputs from the continent. The Aldea de Cortés Fm has been previously interpreted as a lagoon surrounded by tidal-flats and fluvial-deltaic plains. Here it is reinterpreted as a coastal wetland where siliciclastic muddy deposits interacted with shallow fresh to marine water bodies, aeolian dunes and continental siliciclastic inputs. The contact between the Higueruelas and Villar del Arzobispo Fms, classically defined as gradual, is interpreted here as gradual and rapid, because the transition between both units comprises few meters. More importantly, the contact between the Villar del Arzobispo and Aldea de Cortés Fms, previously considered as unconformable, is here interpreted as gradual. The presence of Alveosepta in the Villar del Arzobispo Fm suggests that at least part of this unit is Kimmeridgian, unlike the previously assigned Late Tithonian-Middle Berriasian age. Consequently, the underlying Higueruelas Fm, previously considered Tithonian, should not be younger than Kimmeridgian. Accordingly, sedimentation of the Aldea de Cortés Fm, previously considered Valanginian-Hauterivian, probably started during the Tithonian and it may be considered part of the regressive trend of the Late Jurassic-Early Cretaceous cycle. This is consistent with the dinosaur faunas, typically Jurassic, described in the Villar del Arzobispo and Aldea de Cortés Fms.

Además, estos nuevos datos sugieren que se deberían revisar las correlaciones estratigráficas realizadas previamente entre las unidades estudiadas y aquéllas depositadas en otras áreas adyacentes de la Cuenca Ibérica. La Fm Higueruelas se depositó en la parte media de una plataforma carbonática en la que migraban barras oncolíticas por la acción de las tormentas y en la que la producción de oncolitos disminuía progresivamente hacia la parte alta de la unidad. La Fm Villar del Arzobispo suprayacente ha sido interpretada tradicionalmente como una plataforma interna-lagoon que evolucionó a una llanura mareal. En este trabajo se reinterpreta como una plataforma carbonática interna afectada por las tormentas y en la que se desarrollaban bajíos oolíticos que protegían un lagoon. Esta plataforma también estaba afectada por la llegada de material siliciclástico del continente. La Fm Aldea de Cortés ha sido interpretada previamente como formada en un lagoon bordeado por llanuras mareales y por llanuras deltaicas fluviales. En este trabajo se reinterpreta como depositada en un humedal costero en el que interaccionaban depósitos lutíticos, cuerpos de agua someros de salinidades dulces a marinas, dunas eólicas y descargas continentales de material siliciclástico. El contacto entre las Formaciones Higueruelas y Villar del Arzobispo, definido clásicamente como gradual, es interpretado en este estudio como gradual y rápido, ya que la transición entre ambas unidades ocupa muy pocos metros. De forma más importante, el contacto entre las Formaciones Villar del Arzobispo y Aldea de Cortés, considerado previamente como el resultado de una discontinuidad, es interpretado en este trabajo como un contacto gradual. La presencia de Alveosepta en la Fm Villar del Arzobispo sugiere que al menos parte de la unidad presenta una edad Kimmeridgiense, en lugar de la edad previamente asignada de Titoniense superior-Berriasiense medio. Consecuentemente, la edad de la unidad infrayacente, la Fm Higueruelas, asignada previamente al Titoniense, no sería más moderna que Kimmeridgiense. Por consiguiente, la sedimentación de la Fm Aldea de Cortés, atribuida previamente al Valanginiense-Hauteriviense, habría comenzado probablemente durante el Titoniense y debería ser considerada parte de la tendencia regresiva del ciclo Jurásico Superior-Cretácico Inferior. Todo ello está en consonancia con las típicas faunas de dinosaurios encontradas en las formaciones Villar del Arzobispo y Aldea de Cortés, que presentan afinidades jurásicas.This work was supported by the Spanish projects CGL2011- 22709, CGL2014-52670-P and CGL2013-41295-P DINOTUR of the Ministry of Economy and Competitiveness, the “Sedimentary Basin Analysis” Research Group of the Complutense University of Madrid and a FPU predoctoral contract of the Spanish Ministry of Education.Peer reviewedUniversidad Complutense de MadridMinisterio de Economía y Competitividad (España)Consejo Superior de Investigaciones Científicas [https://ror.org/02gfc7t72]201620162016info:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_6501Publisher's versioninfo:eu-repo/semantics/publishedVersionhttp://hdl.handle.net/10261/133032reponame:DIGITAL.CSIC.
