dc.description.abstractDurante el Jurásico Medio, son comunes a lo largo del Tethys suroccidental las plataformas carbonatadas caracterizadas por facies granosostenidas, dominados por granos no esqueléticos. Las facies oolíticas y peloidales se desarrollaron ampliamente en la Plataforma Aragonesa (Cuenca Ibérica) durante el Bajociense-Bathoniense. El estudio de tres afloramientos localizados entre Obón y Ariño (Cordillera Ibérica) ha permitido la reconstrucción de los dominios sedimentarios de una plataforma dominada por facies oolíticas, peloidales y bioclásticas. Se ha caracterizado la transición entre las áreas someras agitadas (oolíticas) a áreas relativamente más profundas y poco agitadas (peloidales). La distribución de facies observadas a partir de la correlación de los tres perfiles permite discutir la influencia de las variaciones relativas del nivel del maren_US
dc.description.abstractDuring the Bathonian (Middle Jurassic), deposition of grain-supported oolitic facies was common in the shallow domains of the carbonate platforms found along the southwestern Tethys. Oolitic and peloidal facies were also developed in certain marginal areas of the Iberian Basin.A bed-by-bed study of three Bajocian-Bathonian successions in the southeastern part of the Aragonese Platform (NE Spain) allows analyzing the lateral variability of oolitic to peloidal grain-supported facies. Seven different facies have been identified, from oolitic grainstone (inner ramp) to peloidal and bioclastic packstone (middle ramp). The study of the lateral relations of these facies allows identifying the sedimentary environment where they were formed. Overall facies distribution was related to long-term relative sea level changesen_US
