Abstract (in english)
   We model the structure of the lithosphere, its thickness and seismic anisotropy, of the French Massif Central (MC) and the Bohemian Massif (BM), from spatial variations of P-wave delay times and the shear-wave splitting observed at networks of mobile and permanent seismological stations. Joint analysis of anisotropic parameters of P and S waves provide a good resolution for identification of lithosphere blocks characterized by consistent orientations of olivine fabrics within the mantle lithosphere. We suggest that deep sutures, detected as boundaries between domains with different orientation of anisotropic structures, provided paths for mantle fluids participating in the LateVariscan metallogeny in both massifs. The sutures were partly rejuvenated in the Tertiary, predestined a space for rifts and provided channels for the magmas feeding the Cenozoic volcanism
