Abstract (in english)
   In the framework work of the Kola deep drilling project SG-3, complete compressional wave velocity patterns of five amphibolite samples with different fabric and composition were determined experimentally and modeled from the mineral textures to characterize the elastic behaviour of this rock type and to discover variations of bulk rock anisotropy. From the comparison between experimental and modeled data, information on the controls of elastic behaviour is expected. It was concluded, that lattice preferred orientation largely determines the anisotropic physical properties of the bulk rock. However, in addition of the mineral textures factors like open microcracks and open fractures control the elastic properties of bulk rock
