Abstract: El análisis de facies realizado en el Jurásico superior de la Sierra de Aralar (Cuenca Vasco-Cantábrica oriental) ha permitido establecer nuevas precisiones en tomo a la evolución sedimentaria y a la distribución paleogeográfica de los dominios de sedimentación. Se han reconocido dos secuencias deposicionales. La Secuencia inferior, de edad Oxfordiense, está constituida por packstone de peloides y bioelastos que hacia los dominios más distales pasan a wackestone de esponjas, ammonites y belemnites. Estas facie… Show more

“…The depositional environment shows a high variability with marine to lagoonal or lacustrine deposits going from limestones to shale, anhydrite, and sandstones (Campos, 1979;Delfaud, 1970;Peybernes, 1978;Soler, 1971). In the Nappe des Marbres (north-east BCB), Late Jurassic (late Oxfordian-Kimmeridgian) clastic wedges interlayered with ramp carbonates were sourced from the N-NW, attesting for an emerged area (Aurell et al, 2003;Bádenas, 1996) that would correspond to the Basque massifs. In the Arzacq and Mauléon basins, authors (Delfaud, 1970;Puigdefàbregas & Souquet, 1986;Richard, 1986) suggest that these basins were related to basement subsidence accommodated along N°10E to N°50E and N°110E structures.…”
