Subhorizontal materials of the southern part of the Ebro basin exhibit a remarkable degree of internal deformation, about 35 % shortening. Strain integration all along this section has to be considered in order to obtain a more reliable value of the shortening related to the Alpine deformationspaAtribución-NoComercial-SinDerivadas 3.0 Españahttp://creativecommons.org/licenses/by-nc-nd/3.0/es/StrainPyreneesEbro basinjournal articleopen access
