Se dispone discordantemente sobre el Permico o Carbonifero, y consta de las tres facies caracteristicas del Trias germanico. El Buntsandstein presenta un importante desarrollo, particularmente en la zona central o de Reinosa, donde alcanza casi 1.000 m de espesor, reconociendose en el mismo tres macrosecuencias deposicionales aluviales y fluviales (unidades 1, 2 y 3), todas de tendencia vertical positiva. Su sedimentacion tuvo lugar en una fosa tectonica de orientacion W-E y polaridad E, cuyas dimensiones fueron ampliandose con el tiempo a traves de la actuacion de fallas sinsedimentarias. El Buntsandstein es sucedido por un Muschelkak calizo-dolomitico de plataforma marina muy somera, y un Keuper de laguna o albufera arcilloso-evaporitico, en el que se intruyeron masas de ofitas localmente muy importantes. Inmediatamente despues de la sedimentacion del Keuper, movimientos de compresion N-S dieron lugar a pliegues E-W, parcialmente erosionados durante el Triasico terminal. Por ello, los carbonatos del Triasico finalprincipios del Jurasico se disponen localmente en discordancia sobre los materiales del Triasico. Las fallas limitantes de las fosas en las que se acumulo el Buntsandstein se pueden relacionar con un sistema mayor de esfuerzos de desgarre sinistral, localizados principalmente en las importantes lineas de fractura de Ventaniella y Bilbao (de orientacion NW-SE).

La pauta de desgarre invocada es compatible con el regimen de esfuerzos postulados en el rift triasico del Golfo de Vizcaya, asi como con los movimientos de individualizacion de la subplaca iberica que se suponen para aquellos momentos (ZIEGLER, 1982).","PeriodicalId":110220,"journal":{"name":"Journal of iberian geology: an international publication of earth sciences","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114795511","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The studied hay-fill deposits consist of \u0000units, with large-scale foresets that filled most of the depression topped by the \u0000younger sets of offlapping transition-zone units with an overall tabular shape. \u0000As a whole, they generated a Gilbert-type delta morphology that actually is \u0000a summatory of smaller-scale delta units deposited during successive highstands \u0000of sea level. We can observe only these highstand delta deposits. Lowstand \u0000wedges lay under the Present Mediterranean sea. \u0000According tothe sedimentological data, we deduce a deltamodel consisting \u0000of a river plain with rapidly shifting channels, a wave-worked delta front with \u0000gravelly reflective beaches, a sandy delta platform, and a steep delta slope. \u0000The input of sediment was episodic, and the delta remained inactive during \u0000long periods, subjected to wave reworking in the shallow areas.

The various parts afthe delta reacted \u0000differently to these sea-Ievel changes and generated variable facies associations. \u0000The rapid evolution of the bay-fill can be related to high-frequency \u0000fluctuations of sea-level already documented in SE Spain during Late Pliocene \u0000and Quaternary, superimposed on longer-lasting tectonic uplift. \u0000[RESUMEN] \u0000 \u0000La Bahia de Cuatro Calas se formo en el Plioceno superior cuando los \u0000materiales neogenos mas antiguos se flexionaron propiciando una subida \u0000relativa del nivel del mar y la inmersion de la nueva cuenca.
