Abstract

[ES] La distribución de espesores y facies del Cretácico medio de la zona central de la Cordillera Ibérica, permiten identificar un conjunto de umbrales, surcos y escalones. Estos elementos paleogeográficos parecen corresponder con algunos de los elementos tectónicos de la estructura Alpina, segun la dirección principal ibérica, NW-SE, la dirección catalánide, NNE-SSW, la controvertida dirección E-W y en menor medida la dirección NE-SW. Algunos de estos hechos conducen a cuestionar el modelo de aulacdgeno propuesto, para la evolución post-hercínica del dominio de la Cordillera Ibérica.

[EN] The facies and thicknesses distribution of the Middle Cretaceous in the Central area of the Iberian Range let us to identify several thresholds, furrows and steps. These paleogeographical elements are probably related to Alpine movements with two main trending: NW-SE (Iberian), NNE-SSW (Catalanide) and two secondary trending: EW and NE-SW. Some of these facts lead us to question the Aulocogen model proposed for the Post-Hercynian evolution of the Iberian Range domain.
