Abstract: The paper presents the use of the acoustopolarization method for the study of elastic-anisotropic properties of the rock samples from the Kola (SG-3), German (КТВ-НВ) and Outokumpu (OKU) boreholes. Investigations showed that using this method one can reveal elastic anisotropy, evaluate the heterogeneity of rock samples and determine orientation of the elastic symmetry elements. It is possible to determine the type of the rock elastic symmetry without defining 3D distribution for compression and shear waves. In the rock samples from SG-3, КТВ-НВ and OKU the linear acoustic anisotropic absorption (LAAA) is rather common. The results obtained can be used for better interpretation of the palaeodynamic studies of formation conditions of metamorphic rocks.
