La faille normale ductile du massif du Saint Barthélémy. Age et signification de l'extension crustale dans le zone Nord-pyrénéenne

Abstract : The first part of this work is composed of a synthesis about Alpine and Variscan orogenies in the Pyrenees. Recent works (ECORS profile), are presented and discussed. The second part is concerning with the Saint Barthelemy massif. The results of structural and petrological studies are shawn. The structure of the massif is interpreted to be the result of a single progressive deformation event. Structural analysis and thermobarometrical data confirm the existence of extensional tectonics. The singularity of the SBM, with the occurence of a major low angle shear zone, is shawn. In the third part, we proposed a thermotectonical madel which is integrated in the regional geological context.
