Abstract (in english)
   We evaluate 3D body-wave anisotropic parameters-shear-wave splitting (fast S polarizations and delay times of the split slow shear waves) and directional terms of relative P-wave residuals from data of passive seismic experiment BOHEMA II (2004-2005). Data from 34 temporary stations increased substantial density of observations in the Bohemain Massif (BM) and allowed us to scan in detail the upper mantle structure of its northern and eastern parts. For the first time, we delimit domains of the mantle lithosphere in this part of the BM and infer 3D self-consistent models of their fabrics by a joint inversion of the body-wave anisotropic parameters.
