    El cabalgamiento de Valdesotos: consecuencias de la acomodación del acortamiento cenozoico en el zócalo del Sistema Central
    (Geotemas, 2004) Olaiz Campos, Antonio José; Vicente Muñoz, Gerardo de; Vegas, Ramón; González Casado, José Manuel; Muñoz Martín, Alfonso; Álvarez, J.
    We describe and study structural evidences concerning to Alpine tectonics at NE sector o f the Spanish Central System (SCS). In Valdesotos area, the Hercynian basement is uplifted over Mesozoic sediments, throughout a main SW verging thrust. Fault population analysis and geological mapping has been used to look at the relation between structures in the basement and in the cover. As a consequence of accommodation of strains in the basement, kink folds are developed, such as secondary thrust and folds in the tegument. All these meso- and macrostructures seem to answer to a shortening in agreement with the Cenozoic deformation.

    Los corredores de fallas de Regua-Verin y Vilariça: Zonas de transferencia de la deformación intraplaca en la Península Ibérica
    (Geotemas, 2004) Vegas, Ramón; Vicente Muñoz, Gerardo de; Muñoz Martín, Alfonso; Palomino, R.
    A substantial part of the intraplate deformation in the Iberian Foreland is transferred from the Cantabro-Pyrenean border by means of two strike-slip deformation belts, the Regua-Verin and Vilariça fault corridors. The Neogene and recent tectonic activity along these intraplate strikeslip belts is responsible for the onset of a geomorphic barrier between the Duero Basin and the Atlantic Margin.

    Reactivación intraplaca de un relieve apalachiano: Las Sierras de Guadalupe y Montánchez
    (Geotemas, 2004) Álvarez, J.; Muñoz Martín, Alfonso; Vicente Muñoz, Gerardo de; Vegas, Ramón
    In this work, we reconcile structural data analysis with géomorphologie observations to better constrain the morphotectonic evolution of the Guadalupe and Montánchez intraplate ranges located in western central Iberia. Fault slip data analysis and geological mapping suggest a global episode of uplift and northwest tilting during Pliocene times. The Hercynian basement was then uplifted by a NW verging thrust developing Plio-Quaternary syntectonic alluvial fans "Raña deposits". The present-day landscape of these ranges should be interpreted as a result of the interaction of (neo) tectonic forcing and longitudinal fluvial erosion.
