Abstract
El presente trabajo analiza las relaciones entre la sedimentación
y la estructuración del Arco de Cazorla-Alcaraz (Prebético Externo)
durante el Mioceno superior en el saliente de Vianos (Albacete, España). Se describe la creación del depocentro local en la cuenca de
antepaís más tardío que se produce por avance del arco. El surco fue
delimitado por un pliegue en rodilla que tuvo expresión paleogeográfica y se colmató en condiciones marinas, en un episodio transgresivo posiblemente durante el final del Tortoniense. Se trata por
tanto de uno de los puntos con depósitos miocenos marinos más
jóvenes en el sector septentrional del Prebético Externo.
The present work analyzes the relationships between sedimentation and structuring of the Cazorla-Alcaraz Arc (External Prebetic) during the late Miocene in the Vianos salient (Albacete, Spain). The creation of the local depocenter in the foreland basin that occurs by the last arc advance is described. The foredeep was delimited by a fault-bend fold that had paleogeography expression and was filled in marine conditions, in a transgressive context, possibly during the end of the Tortonian. It is therefore one of the points with the youngest marine Miocene deposits in the northern sector of the External Prebetic
