• Resumen

  • From the structural study (using field, microstructural and anisotropy of magnetic susceptibility data) of the central traverse across the Lys pluton (Pyrenean Axial Zone), we propose that the emplacement of this pluton is synkinematic with the Variscan deformation of the Cambro-Ordovician schists that form its northern envelop. The late emplacement events involve a dextral transpressional deformation leading to the development of the Esera-Cistain and Caillaouas ductile shear zones. These Variscan shear zones were reactivated during the Pyrenean orogeny.
