Abstract

In the studied area, the Cabuerniga Group reaches its greatest known thickness, approximately 2.500 m. It is made up of 4 Formations (Aguilar, Arcera, Aroco and Loma Somera), laid down respectively in shallow lakes, alluvial plains, lagoons and tidal flats. The palaeogeographical evolution of the area is established through cartographic analysis of the relationships between these Formations. A substantial part of the succesion is probably jurassic, instead of Departamento de Geología. Facultad de Ciencias. Ap. 644. Bilbao. * 5 cretaceous as currently believed. During some intervals, the depositional processes were influenced by contemporaneous tectonics, notably in the vecinity of the diapiric anticline of Aguilar.
