Résumé: The Iberian Chain is a wide intraplate deformation zone formed by the tectonic inversion during the
Pyrenean orogeny of a Permian –Mesozoic basin developed in the eastern part of the Iberian Massif. The N
– S
convergence between Iberia and Eurasia from the Late Cretaceous to the Lower Miocene times produced
signi cant intraplate deformation. The NW –SE oriented Castilian Branch of the Iberian Chain can be
considered as a “key zone ” where the proposed models for the Cenozoic tectonic evolution of the Iberian
Chain can be tested. Structural style of basin inversion suggests mainly strike slip d–isplacements along
previous NW –SE normal faults, developed mostly during the Mesozoic. To con rm this hypothesis, structural
and basin evolution analysis, macrostructural Bouguer gravity anomaly analysis, detailed mapping and
paleostress inversions have been used to prove the important role of strike slip deformation. In addition, we
demonstrate that two main folding trends almost perpendicular (NE SW t–o E W an–d NW SE) w–ere
simultaneously active in a wide transpressive zone. The two fold trends were generated by dierent
mechanical behaviour, including buckling and bending under constrictive strain conditions. We propose that
strain partitioning occurred with oblique compression and transpression during the Cenozoic.
Résumé: Este trabajo estudia el impacto que ha tenido la implantación de un sistema de gestión de la calidad, de acuerdo con los requisitos establecidos en la Norma Internacional ISO 9001:2000, en el Archivo General de la Universidad Complutense de Madrid. Para ello, se han analizado las opiniones del personal y de los usuarios del archivo antes y
después de obtener la certifi cación de dicho sistema de gestión. Los resultados presentados señalan que la certifi cación no produce ninguna modificación en la percepción que tienen los usuarios del archivo sobre la calidad de los servicios de transferencia
y búsqueda documental, así como sobre la calidad de la interacción entre el personal y los usuarios. En contraste, el personal valora muy favorablemente la certificación del archivo obteniéndose mejoras que son significativas en el área de gestión de los procesos de trabajo y, en concreto, en su documentación, coordinación entre procesos, definición de responsabilidades, o medición de su desempeño. Así mismo, y en opinión del personal, son significativas las mejoras que se producen con relación
a algunos aspectos del funcionamiento del archivo como son: una mayor participación en el establecimiento de objetivos en su trabajo, una mayor identificación con la organización,
y en la apreciación de que la mejora de la calidad del servicio es uno de los objetivos prioritarios que se deben conseguir. Estos resultados pueden servir como referencia para convencer a los directivos de otros servicios de información y de documentación, de las ventajas que tiene la implantación de un sistema de gestión de la calidad y su posterior certificación.[ABSTRACT]
This work studies the impact of the introduction of a quality management system, on the General. Archive of the Complutense University of Madrid in line with the
requirements of International Standard ISO 9001:2000. For this study, the opinions of the personnel and users of the archive before and after its obtaining certifi cation with
regard to the said management system were analysed. The results show that certification led to no change in user perception of the archive regarding the quality of document
transfer and search services, or regarding the quality of interaction between personnel and users. In contrast, the personnel valued archive certification positively, regarding it as providing important improvements in the area of work process management, and specifically in its documentation process, the coordination between processes, the definition of responsibilities, and the measurement of performance. In the opinion of the archive personnel, the improvements made with respect to certain aspects of the
functioning of the archive were signifi cant, e.g., greater participation in establishing objectives, greater identification with organisation, and the appreciation that improvement of the quality of service should be a key objective. These results can be used as a reference
tool to convince other information and documentation service managers of the advantages of introducing a quality management system and seeking subsequent certification.

Résumé: During the most active rifting stages in the northwestern sector of the Iberian Basin (Cameros Basin and Aragonese Branch of the Iberian Range), thick sequences of continental clastic deposits were generated. Sandstone records from Rift cycle 1 (Permo-Triassic) and Rift cycle 2 (Late Jurassic-Early Cretaceous) show similarities
in composition. Based on the most recent data, this paper
describes sandstone petrofacies developed during both rifting periods. Six petrofacies can be distinguished: two associated with Rift cycle 1 (PT-1 and PT-2) and four with Rift cycle 2 (JC-1 to JC-4). All six petrofacies can be classifi ed as sedimentoclastic or
plutoniclastic. Sedimentoclastic petrofacies developed during early rifting stages either through the recycling of pre-rift sediments or signifi - cant palaeogeographical changes. These facies comprise a thin succession (
