Tectónica sinsedimentaria en el Aptiense y Albiense de la región vascocantábrica occidental.

Abstract

The Urgonian materials of the Peri-Asturian domain were formed under conditions of marked differential subsidence the main effects of which, apart from the large thicknesses connected with throughs, were reef control with the creation of steep slopes, the appearance of growth faults connected xvith deltas and the development of salt domes perforations. At the same time and at a steady rate, severa1 tectonic pulsations were also produced, originating discordances and the rejuvenation of reliefs existing in the source area. It can be Departamento de Geología (Estratigrafía), Facultad de Ciencias, Bilbao. * 23 assumed that alí these displays of sinsedimentary tectonics proceed from a common origin, specifically the Biscay>s guíE opening within the formative process of the Northern Atlantic.
